Summary: In this study, a waxberry-like CeO2 photocatalyst with enhanced visible-light-driven photocatalytic performance was achieved through Sm doping and Ag quantum dots anchoring. The doping increased the concentration of oxygen vacancies in CeO2, resulting in a narrower bandgap and improved visible light utilization efficiency. The captured electrons by the vacancies effectively restricted the recombination of photo-excited carriers, leading to enhanced photocatalytic activities.

Summary: In this study, a nontrivial excitonic transition regulation strategy was proposed to achieve sub-bandgap light absorption in low-dimensional semiconductor-based photocatalysts. By introducing bismuth vacancies, the light absorption cut-off edge could be effectively extended up to 500 nm. The broadening of light absorption was attributed to the promotion of excitonic transition caused by bismuth vacancy-induced excited-state symmetry breaking.

Summary: This work involves tuning the band gap of titanium dioxide (TiO2) nanoparticles through carbon doping during sol-gel synthesis. By using polydiallyldimethylammonium chloride (PDADMAC) as the carbon source, the band gap energy of TiO2 was reduced significantly. The interaction between carbon, titanium, and oxygen atoms was found to contribute to the reduction in band gap energy, resulting in structural modifications and enhanced photocatalytic activity of the TiO2 nanoparticles, as demonstrated in the detailed investigation of the photodegradation kinetics and thermodynamics of methylene blue.

Summary: In order to address global warming and energy crisis, the development of photocatalysts with broad-range light-absorption and efficient carrier transfer is urgently needed for artificial photosynthesis and green chemical production. In this study, novel CsPbBr3 nanocrystal coupled NiFe-LDH (CPB/NiFe-LDH) Z-scheme photocatalysts were constructed for efficient photocatalytic CO2 reduction. The unique CPB/NiFe-LDH Z-scheme heterojunction allowed tailored photogenerated carrier transfer behaviors, resulting in significantly improved carrier transfer ability and reduction potential compared to pristine NiFe-LDH. By precisely controlling the CPB/NiFe-LDH ratio, tunable Z-scheme photocatalytic reduction capability and charge separation efficiency were achieved, with the optimal CPB/NiFe-LDH-2 photocatalyst showing a 2-fold increase in electron consumption rate compared to pristine NiFe-LDH. This work provides an innovative approach to construct photocatalysts with tunable Z-scheme charge transfer behavior, which can be applied in various solar energy conversion applications.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
