Summary: TiO2 nanotube (TNT) photoanodes demonstrate effective oxygen evolution reaction (OER) in photoelectrochemical water oxidation. This study reveals that beta-PbO2 nanoparticles are selectively deposited on the catalytic site of the upper part of the TNT array with a length of around 1 μm, resulting in photocurrent decay. The deposition of PbO2 nanoparticles on both inner and outer surfaces of the tube walls is consistent with the charge separation mechanism at the space charge layers. The position of the OER site varies with the incident light wavelength due to the change in light penetration depth.

Summary: In this study, a facile surface treatment method using Fe2+ ions was demonstrated to enhance the photo-electrochemical water oxidation of nanostructured tungsten oxide (WO3) film. The optimized WO3 film with a Fe:W ratio of -1:25 showed a 3 times higher and more stable photocurrent under back illumination compared to untreated WO3, indicating the success of the surface treatment. The improved performance was attributed to the enhanced charge transfer process at the interface, resulting in the reduction of unwanted recombination.

Summary: The effectiveness of electrochemical WO3 modification on improving the photoactivity of native air-formed TiO2 layers was studied. Laser treatment was found to result in smaller and better dispersed WO3 particles on the surface, as well as enhanced oxygen deficiency and absorptivity. These features, combined with the narrower bandgap, higher donor density, and lower flat band potential of the laser-treated WO3/TiO2 systems, enabled faster oxygen photoanodic evolution and a cathodic shift in onset potential. Additionally, the laser treatment significantly enhanced the photoelectrocatalytic performances for UV-assisted methanol anodic oxidation.

Summary: V- and W-containing oxide-phosphate layers were formed on titanium through plasma electrolytic oxidation. The replacement of vanadate with tungstate was studied to understand its effect on voltage-time responses, surface morphology, composition, optical and photocatalytic properties. The incorporation of V and W into the coatings was mainly attributed to thermolysis of vanadungstophosphate hetero-polyoxoanions, while high concentrations of polyphosphate species contributed to the amorphization of coatings and the formation of a titanium phosphate matrix. The formed coatings showed photocatalytic activity in the degradation of methyl orange.

Summary: Nanocomposites with outstanding visible light photoelectrochemical characteristics have been synthesized. Ternary chalcogenides (TC) are excellent components in forming nanocomposites with classic semiconductors like TiO2 due to their narrow bandgaps and efficient visible light absorption. TiO2/AgBiS2 binary nanocomposite was successfully synthesized and deposited on FTO via EPD technique in this study. The nanocomposite showed enhanced visible light absorption and reduced bandgaps, confirmed by XRD, FESEM, mapping, and UV-DRS results. Electrochemical characterization and photocatalytic degradation experiments demonstrated its excellent performance in PEC application.

Summary: Harnessing solar energy for clean and sustainable fuel production through photoelectrochemical water oxidation has been extensively studied. However, the efficiency of the light-driven reaction in artificial photosynthesis is limited. In this study, we experimentally analyzed the effect of electrolytic pH on photoelectrochemical syngas production by adjusting the pH of KOH and NaOH electrolytes. The highest photocurrent of 13.80 mA cm(-2) and a photon-to-current conversion efficiency of 43.51% were achieved at pH 13 in the aqueous NaOH electrolyte.

Summary: WO3@ZnO core-shell nanoarrays with a Z-scheme heterojunction structure were fabricated by combining electrodeposition and dropping process and used as photoanodes for the production of hydrogen peroxide (H2O2). The WO3@ZnO nanoarray photoanode exhibited a significantly higher photocurrent density (1.57 mA·cm(-2)) compared to the pure ZnO nanoarray photoanode. Under AM 1.5 G (100 mW·cm(-2)) conditions, the WO3@ZnO photoanode achieved a high photoconversion efficiency of 0.53% and Faradic efficiency of 33% for H2O2 production. This work provides an effective approach for the application of Z-scheme heterojunction in the photoelectrochemical synthesis of H2O2.

Summary: Semiconducting heterojunction-based devices using transition metal oxides like tungsten (WO3) and titanium (TiO2) exhibit the best photocatalytic performance currently, due to the ability to optimize electron/hole injection barriers through size, morphology, and composition adjustments. However, this approach requires a deep understanding of structure-property relationships that are difficult to access through experiments.

Summary: The study showed that modification of Ti0.97Ru0.03O2/Ti electrodes with WO(3) improves efficiency and stability in electrochemical treatments. Increasing the amount of WO(3) in the oxide layer enhances the number of active sites and electron transfer rates. Furthermore, even a small addition of WO(3) can prolong the electrode's lifetime.

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.
