Article Abstract
Herein, we report a catalytic defluorinative arylation of aldehydes with (per) A fluoroarenes facilitated by a pincer-based PheBox-Bi(I) under mild conditions. The protocol features various novel aspects in bismuth redox catalysis; namely, (1) a catalytic 1,2-aryl migratory insertion to forge a C─C bond, (2) an unprecedented example of multicomponent reaction through four elementary organometallic steps at a Bi center, (3) an unusual strategy for Bi(I) compounds regeneration via O─Si reductive elimination. Experimental and computational studies aided in dissecting the various mechanistic aspects of the bismuth redox cycle.

Fenton oxidation technology utilizing hydrogen peroxide is recognized as an effective method for producing reactive oxygen species (ROS) to facilitate the degradation of antibiotics. However, the requirement for strongly acidic conditions during this process significantly restricts its broader applicability. In this study, we synthesized black phosphorus (BP) nanosheets by exposing the {010} crystal planes and then constructed a 0D/2D BP/BiMoO (PBMO) heterojunction to function as a Fenton catalyst.

Despite its strong pollutant degradation capability, BV remains ineffective for hydrogen evolution, whereas CV, with favourable band position, actively participates in hydrogen evolution. BV shows a pollutant degradation rate of 90% in 1 hour but does not produce hydrogen, while CV exhibits a hydrogen evolution rate of 590.

The low catalytic efficiency of piezoelectric materials is a core limitation of piezocatalytic therapy. This study employed a dimensional engineering strategy to construct a two-dimensional (2D) zirconium-based metal-organic framework (U67-2D) with lattice distortion-enhanced piezoelectric properties for ultrasound-responsive tumor piezocatalytic immunotherapy. Structural analysis revealed that lattice distortion within the 2D structure significantly enhanced the piezoelectric polarization effect by reducing material symmetry, thereby improving charge carrier separation efficiency and boosting reactive oxygen species (ROS) generation efficiency.

Vacancy-ordered Bi-based perovskites, such as CsBiBr (CBB), exhibit relatively high Lewis acidity due to Bi⁺ centers, providing favorable acidic sites for organic transformations. Coupled with their tuneable optoelectronic properties, these features render CBB an efficient photocatalyst for various acid-catalyzed reactions. In this study, CBB is conjugated with a classical Ru(II)-polypyridyl photosensitizer (RuPS) to form a hybrid material, CBB/RuPS, capable of facilitating thermodynamically favourable inner-sphere electron transfer.

This study investigates the synergistic photocatalytic activity of mixed bismuth oxyhalides (BiOI and BiOCl) and the critical role of iron doping in enhancing the Cr(VI) reduction. By employing FeCl as both a chloride source and iron dopant precursor, we achieved in situ Fe incorporation into bismuth oxyhalides (BiOX; X = Cl/I) during a one-pot coprecipitation synthesis at room temperature. The resulting iron-doped BiOX formed flower-like particles integrated with NH-UiO-66, a zirconium-based metal-organic framework (MOF), creating a Z-scheme heterojunction composite.
