Summary: Inspired by natural photosynthesis, we constructed a Z-scheme heterojunction with an N-doped C layer as an electron bridge to effectively improve photocatalytic hydrogen production performance on TiO2/ZnIn2S4. The T@NC-A/ZIS-72 heterojunctions exhibited significantly higher hydrogen production activity, approximately 12.1 and 97.9 times higher than ZnIn2S4 and TiO2@NC-A, respectively. The excellent electron migration ability of the carbon layer accelerated photocatalytic hydrogen production. Our design introduces a component to provide a dedicated charge transport pathway, offering a new perspective for enhancing photocatalytic performance.

Summary: In this study, a C/N co-doped rich-defect TiO2 photocatalyst (C/N/DBD-TiO2-x) was prepared for the first time by DBD plasma discharge treatment in the mixed atmosphere of CO, N2 and H2. The introduction of oxygen defects, C doping and N doping was successfully achieved through DBD plasma discharge treatment. This led to a reduction in the forbidden band width and efficient separation and transfer of electron hole pairs. Additionally, the DBD plasma discharge treatment increased the specific surface area, pore volume and pore size of TiO2. The visible light catalytic performance evaluation showed a degradation rate of 98.05% for MB solution. The new plasma discharge method overcomes the limitations of traditional modification methods, providing a new and more convenient technology for TiO2 modification.

Summary: In this research, Ru-doped TiO2 nanotube arrays were prepared and the effects of annealing temperature, Ru content, and test temperature on their electrocatalytic performances for hydrogen and oxygen evolution reactions were investigated. The results showed that the unannealed Ru-doped TiO2 nanotube arrays had superior activity for hydrogen evolution reaction, and the annealed arrays at 450 degrees C showed excellent activity for oxygen evolution reaction. The Ru content significantly affected the electrochemically active surface area and the charge transfer resistance. The optimal performance was achieved when the Ru content was 6%. Furthermore, the electrocatalytic activity of Ru-doped TiO2 nanotube arrays improved with increasing test temperature.

Summary: This study investigates the effect of N and Pt co-dopant on the modification of TiO2 photocatalyst and compares different mode preparations. The results show that the NPseq-TiO2 photocatalyst prepared in sequential mode exhibits higher photocatalytic activity than unmodified TiO2 and PNrev-TiO2 photocatalyst. This is attributed to the incorporation of N elements and the formation of oxygen vacancies defects, which enhance the surface properties of the photocatalyst.

Summary: The study investigates the formation of nanocomposites by incorporating TiO2 (at two different loadings) with plasmonic RuO2 nanoparticles (with an average size of (3 +/- 0.7) nm). XRD results show the formation of RuO2 in the rutile phase, with high levels of TiO2 forming the rutile phase and lower levels forming the anatase phase. The TiO2 incorporation significantly enhances the reactivity of RuO2 in the artificial photosynthesis reaction under visible light, leading to increased catalyst activities and changed reaction selectivity.

Summary: Supported nickel nanoparticle catalysts with different morphologies were studied in the non-thermal plasma-promoted dry reforming of methane. Catalysts with dendritic and flake-like particles, which had a higher ratio of (111) lattice planes and surface structures in the nanoscale, showed higher conversions and yields compared to spherical analogues. This is attributed to the favorable (111) faces for methane dissociation and the potential for microdischarges formation around their small surface features. All tested materials exhibited higher methane conversion and hydrogen production compared to reactions conducted without a catalyst.

Summary: This paper investigates the degradation of perfluorooctanoic acid (PFOA) using a photocatalyst (bismuth oxyiodide, BiOI) and a fungal biocatalyst (Cunninghamella elegans). Both the photocatalyst and biocatalyst can degrade 35-40% of 100 ppm PFOA individually, with 20-30% defluorination. However, a combination of the two treatments results in a higher degradation rate of 90% and defluorination rate of 60%. The study also identifies the products formed during the degradation process and reveals the mechanism of PFOA biodegradation.

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.
