Summary: The study found that partially replacing La with Ca and Ce in Rh/perovskite catalysts can improve the specific surface area of the support and activate oxygen mobility, leading to enhanced catalytic performance. However, for Rh/LaCeAlO3 0.3% catalyst, although it showed low carbon accumulation and longer reaction time, deactivation occurred after 14 hours.

Summary: Most photodynamic therapeutics (PDTs) used in cancer treatment require oxygen to efficiently terminate cancer cells, but they are not effective in hypoxic conditions. Rh(III) polypyridyl complexes have been found to have photodynamic therapeutic effect in hypoxic conditions when exposed to UV light. This study proposes the coordination of a BODIPY fluorophore to a rhodium metal center to enhance the reactivity of rhodium under visible light.

Summary: Here, we present a visible-light enabled platform for the photochemical reduction of 1,2-dicarbonyl compounds to alpha-hydroxy carbonyl derivatives using diisopropylethylamine as a reductant. This reaction shows tolerance towards various fragile groups such as methylthio, halogens, cyano, and heterocycles. Experimental studies and DFT calculations confirm a double hydrogen atom transfer (HAT) pathway.

Summary: Bifunctional oxygen-doped graphitic carbon nitride (OCN) was fabricated to activate peroxymonosulfate (PMS) for degrading imidacloprid (IMD). The modulated electronic structure of OCN promoted the adsorption, electron transfer, and formation of the redox site of PMS, leading to improved removal efficiency. Additionally, the PMS oxidation and reduction pathways on OCN, as well as the multiple reactions of superoxide radicals, contributed to the generation of singlet oxygen as the main active species.

Summary: An effective strategy combining defect engineering and heteroatom doping was developed to expand the visible light response range and construct an active surface for TiO2. A binary core-shell structure with an outer defect-layer shell and an inner crystalline anatase TiO2 core was achieved through plasma-induced carbon doping. The narrowed bandgap and improved photo-induced charge separation contributed to the outstanding photocatalytic activity, while the outside oxygen-vacancies layer and interstitial carbon doping enhanced the photoelectrochemical performances significantly.
