Summary: Novel Mo/Mo2C/CoAl-LDH photocatalysts were fabricated and applied for efficient PMS activation and degradation of typical pollutants. The exceptional performance of the Mo/Mo2C/CoAl-LDH/PMS/Vis system was attributed to the synergism of the Mo-Co dual active components and the involved photocatalysis. The toxicity assessment indicated that most of the degraded intermediates became more eco-friendly to the environment.

Summary: Two-dimensional catalysts with photothermal effect are being researched to catalyze the release of H2 from NaBH4 in energy saving systems. This study explores oxygen vacancy enriched CoFe-LDH derivatives for NaBH4 hydrolysis catalyzed by photo-thermal synergy. The CoFe-300 degrees C with the highest concentration of oxygen vacancy shows the best photo-thermal synergistic catalytic performance, achieving a hydrogen production rate of 1877.5 mmol g-1 h-1 and maintaining high efficiency after 5 cycles. This study reveals an enhanced photo-thermal synergistic catalytic mechanism for the hydrolysis of NaBH4.

Summary: The photo-catalytic degradation of a textile azo-dye Methyl Orange was studied in an innovative unit with a titanium dioxide catalyst layer, activated by UVB irradiation. Various parameters such as TiO2 dosage, dye concentration, pH, flow-rate, hydraulic load, and irradiation power were found to influence degradation rates. An increase in flow rate led to higher degradation kinetics, while further increase associated with modification of hydraulic load resulted in lower rates. Additionally, the kinetic rates increased with higher UVB intensity.

Summary: Designing and controlling heterostructures, such as the Cu2O/WO3 heterostructure studied in this work, can effectively improve the photoelectrochemical performance. The thickness of the Cu2O layer was found to play a crucial role in the performance enhancement of the heterostructure. By analyzing various characteristics, it was revealed that the built-in electric field at the interface dominated the efficient separation of electron-hole pairs in the heterostructure.

Summary: This article reports on a novel Cu2O/g-C3N4 heterostructure that exhibits both photocatalytic and electrocatalytic functions for water splitting. The heterostructure shows lower overpotential and higher photocatalytic hydrogen evolution compared to g-C3N4, thanks to increased catalytically active sites and reduced charge transfer resistance.

Summary: Carbonylation of ethanol with CO2 as carbonyl source is significant and challenging due to the harsh conditions for activating inert CO2. In this study, a photo-thermal cooperative strategy is proposed to activate CO2 to reactive CO through photo-catalysis with the assistance of *H from alcoholic O-H bond dissociation. An interfacial site and oxygen vacancy rich Cu2O-SrTiCuO3-x catalyst is designed to achieve high selectivity for targeted O-H activation. The photo-driven activation of CO2 decreases the activation energy and suppresses the cleavage of alpha-C-H bond.

Summary: Designing efficient catalysts for photo-Fenton organic contaminant degradation is crucial in addressing environmental deterioration and energy crises. In this study, we successfully synthesized a highly effective and stable Z-scheme NiFe LDH/Bi4O5I2 catalyst for tetracycline (TC) photodegradation. The optimized catalyst demonstrated over 95% TC degradation efficiency under visible light irradiation. It exhibited excellent stability, low metal ions leaching, and wide pH applicability, making it a potential candidate for TC elimination. The enhanced performance can be attributed to the Z-scheme heterojunction and accelerated H2O2 decomposition, facilitating the synergy between photocatalysis and Fenton reaction. This work provides insights for designing Z-scheme catalysts for photo-Fenton degradation of organic contaminants and other solar energy applications.

Summary: This study investigates the mechanisms of CO2 reduction through density functional theory calculations on Cu2O photocatalyst. The results reveal the interfacial charge transfer and bond dynamics under plasmonic excitation, showing that oxygen vacancies assist in reducing the activation barrier of C-O bond cleavage. Furthermore, the integration of Cu2O with plasmonic metals can further decrease or eliminate the remaining barrier at plasmon-excited states.

Summary: In this study, density functional theory calculations were performed on Cu2O to investigate the interfacial charge transfer and bond dynamics during CO2 reduction under plasmonic excitation. The presence of oxygen vacancies lowers the activation barrier for C-O bond cleavage, and this barrier can be further reduced or eliminated by plasmon-excited states when Cu2O is integrated with plasmonic metals.

Summary: In this study, Cu2O@Cu composites were synthesized using a two-step liquid-phase reduction method for adsorption of methyl orange pollutant. The adsorption process followed pseudo-first-order kinetic and Freundlich isotherm, with the maximum capacity of the adsorbent being 498 mg/g. The adsorption mechanism was identified as electrostatic attraction between the positively charged adsorbent and the sulfonic acid group of MO.
