Bismuth in Radical Chemistry and Catalysis

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 63(8)

Published: Nov. 22, 2023

Abstract Whereas indications of radical reactivity in bismuth compounds can be traced back to the 19 th century, preparation and characterization both transient persistent bismuth‐radical species has only been established recent decades. These advancements led emergence field chemistry, mirroring progress seen for other main‐group elements. The seminal fundamental studies this area have ultimately paved way development catalytic methodologies involving intermediates, a promising approach that remains largely untapped broad landscape synthetic organic chemistry. In review, we delve into milestones eventually present state‐of‐the‐art Our focus aims at outlining intrinsic discoveries inorganic/organometallic chemistry contextualizing their practical applications synthesis catalysis.

Modulating the doping state of transition metal ions in ZnS for enhanced photocatalytic activity

Chemical Communications, Journal Year: 2023, Volume and Issue: 59(75), P. 11280 - 11283

Published: Jan. 1, 2023

Transition metal ions (M = Ag+, Cu2+, Co2+, and Cr3+) are surface or homogeneously doped into ZnS via facile cation-exchange reaction, while Ag+ Cu2+ doping does not induce sulphur vacancies (Vs) zinc (VZn), Co2+ Cr3+ induces Vs. The catalysts exhibit greatly higher activity than the homogenous for H2 evolution CO2 reduction. important role of state on affecting photo-absorption, carrier separation efficiency, photoreaction kinetics has been systemically investigated proposed. This work sheds light future design fabrication high-performance photocatalysts by element doping.
