Summary: A portable photocatalytic fuel cell (P-PFC) with a simple structure and high performance was proposed. The P-PFC had a photoanode composed of F-doped tin oxide (FTO)/TiO2 seed layer/TiO2 nanorods, which expanded the absorption range of solar light. The cathode consisted of a printed silver paste on a waterproof and breathable layer, enabling efficient oxygen absorption from the air. Encapsulated in a hot-melt film, the P-PFC could be easily replaced and was compatible with all types of fuels. Under UV light of 30 mW/cm2, the P-PFC achieved a photocurrent of 2.8 mA/cm2 and a power density of 0.49 mW/cm2 using 1 mol/L methanol as fuel. The system remained functional even at a low power density of 2 mW/cm2. Additionally, the P-PFC demonstrated a maximum degradation efficiency of 74.3% for methylene blue (MB), indicating its potential for simultaneously degrading organic pollutants and generating electricity.

Summary: A new semiconductor/cocatalyst, Ni2P sensitized TiO2 nanotube arrays photoanode (Ni2P/TiO2-NTAs), is developed for photoelectrocatalytic urea oxidation reaction (PEC-UOR) with high efficiency. The 1D TiO2-NTAs structure accelerates urea molecules diffusion and promotes CO2 gas release at the electrode interface. Meanwhile, Ni2P is also beneficial to urea molecule absorption and CO2 desorption and enables to lower the energy barrier for amine (N-H) dehydrogenation. Furthermore, the robust interfacial charge transfer pathway between Ni2P and TiO2 interface promotes the separation of photogenerated electrons and holes.

Summary: In this study, a polyaniline/g-C3N4/Bi2O3/Ti photoanode was successfully prepared and assembled with a Cu cathode to construct a visible light responsive photocatalytic fuel cell (PFC) for the simultaneous decomposition of rhodamine B and electricity generation. The PFC exhibited a degradation rate, maximum photocurrent density, and maximum power density of 91.23%, 0.086 mA cm-2, and 4.78 mu W cm-2, respectively. These values were significantly higher than those of PFCs with g-C3N4/Bi2O3/Ti and Bi2O3/Ti photoanodes. The improved performance was attributed to the type II heterojunction structure formed among polyaniline, g-C3N4, and Bi2O3 in the polyaniline/g-C3N4/Bi2O3/Ti photoanode. The 7c-7c conjugated structure of polyaniline facilitated the rapid transfer of electronic charge, leading to enhanced spatial separation efficiency and extended visible light response wavelength.

Summary: A multi-species transport model considering electron/hole transport, organic/hydroxyl ion transport, and photoelectrochemical reaction was developed for one-dimensional TiO2 nanotube array photoanode. The simulated results are in good agreement with experimental data. Increasing organic/hydroxyl ion concentrations and illumination intensity improves the performance of the photoanode, while decreasing the wavelength decreases the performance. Thinner nanotube wall thickness yields better performance, with an optimum nanotube layer thickness for optimum performance.

Summary: In this study, a nitrogen-rich carbon nitride (C3N5) modified TiO2 nanotube arrays (TNAs) photoanode was constructed to enhance the photocatalytic performance for tetracycline degradation under visible light. The introduction of C3N5 improved the photoconversion efficiency and reduced the recombination efficiency of photoinduced carriers. Radical capture experiments revealed the predominant reactive species involved in tetracycline degradation in the photoelectrocatalytic system, and density functional theory calculations and HPLC-MS spectra provided insights into the possible degradation pathway. Furthermore, the toxicity estimation showed a decrease in the overall toxicities of tetracycline after degradation in the photoelectrocatalytic system.

Summary: The performance of the photocatalytic fuel cell is mainly determined by the photoanode, and the g-C3N4/WO3/TiO2/Ti photoanode significantly improves the maximum photocurrent density. The excellent performance is mainly attributed to the co-doping of TiO2/Ti with g-C3N4 and WO3, which expands the light absorption range and improves carrier mobility.

Summary: To address the issues of rapid recombination, limited optical response range, and single transmission path in electron-hole pairs, a polydopamine (PDA)/WO3 and TiO2 composite photoanode was prepared. The performance of this photoanode was significantly enhanced, with a maximum photocurrent density of 2.03 mA cm(-2) and a maximum power density of 18.68 μW cm(-2). This was attributed to the good carrier mobility of PDA and the stepped heterojunction structure formed by PDA-11.5%/WO3/TiO2/Ti, which promoted the separation and utilization of electron-hole pairs.

Summary: Ammonia is a promising fuel for solid-oxide fuel cells (SOFCs), and there is a pressing need to develop stable anodes for direct-ammonia SOFCs (DA-SOFCs). In this study, a novel DA-SOFC anode was developed using nickel and iron nanoparticles supported on a lanthanum titanium oxynitride support, mixed with copper and gadolinium-doped ceria. The anode showed excellent electrochemical activity and stability, with no signs of physical degradation or gas production during operation. These results suggest that oxynitride-based materials are a stable and active choice for DA-SOFC anodes.

Summary: This study successfully synthesized various types of thiolated-graphene quantum dots (GQDs) and utilized them in a one-droplet microfluidic paper-based analytical device for the simultaneous multi-sensing of heavy metal ions. The GQDs were functionalized and stabilized on the surface of hydrophobic fiber-glass, enabling colorimetric chemosensing of ions including iron, copper, cobalt, mercury, chrome, manganese, and nickel. The results were confirmed using fluorescence spectrometry, and the platform showed potential for facile metal ion detection in human urine models and environmental fluids.

Summary: Laboratory illumination is strong enough to create a photostationary state (PSS) of amphiphilic azo-benzene compounds in water. The [cis]PSS/[trans]PSS ratios were observed to be 0.33-1.2 in D2O and 0.37-3.8 in dimethyl sulfoxide-d6. ortho-Fluoroazobenzene amphiphiles show higher cis-isomer concentration at equilibrium compared to non-fluorinated compounds due to differences in optical absorption profiles. The kinetics of isomerization were measured using UV-Vis spectroscopy and the ratio of trans-to-cis rates does not directly correlate with the observed PSS. The half-life for PSS formation is 40 minutes for fluorinated compounds and 80 minutes for non-fluorinated compounds.

Summary: This study designed an integrated structure of Cu2O@Au/Cu2O heterostructure particles, which achieved significantly enhanced photocatalytic performance by simultaneously considering the integrated structural characteristics and localized surface plasmon resonance (LSPR) effect. Experimental characterization and theoretical simulation confirmed the three-in-one synergy of the integrated heterostructure, including the LSPR effect of Au nanoparticles, the light scattering based on core-shell heterostructure, and the effective charge separation based on inter-embedded heterostructure. The concept of integrated heterostructure cooperated with LSPR effect provides a new strategy for designing future catalysts.

Summary: In this study, the recombination of separated ion-radical states (SIRS) in PAPh films was analyzed, and it was found that the contribution of X-SIRS recombination to total luminescence varies with different environments. It was also shown that the recombination of labile SIRS is independent of the nature of the atmosphere. The study theoretically substantiated that SIRS recombination can occur via the transfer of both positive and negative charges, and the efficiency of thermal activation of recombination processes depends on the ratio of radiant and conductive channels of energy transfer.

Summary: Bifunctional hybrids containing photochromic indolyl(thienyl) diarylethenes and an ionochromic rhodamine moiety connected by a dimethylene spacer were synthesized. These hybrids exhibit absorption at 450-455 nm and fluorescence at 560 nm in toluene. UV light triggers ring-closed non-fluorescent diarylethene formation, which can be reversed under visible light or in the dark. In the presence of H+ cation, a naked eye effect is observed with the opening of the rhodamine-spirolactam ring and a pink-crimson coloration at 561 nm accompanied by intense long-wavelength emission at 586 nm. This process is reversible by exposure to triethylamine, as confirmed by NMR experiments. The light-induced isomerizations and proton-induced transformations were explained using computational methods. Reversible switching of fluorescent properties can be achieved by light irradiation and proton.
