Heterogeneous Semiconductors as Versatile Photocatalysts for Organic Synthesis

, 2022
Visible-light is a powerful “reagent” for sustainable synthetic organic chemistry. In particular, the combination of photo- and nickel catalysis (metallaphotocatalysis) has emerged as a valuable strategy for carbon–carbon and carbon–heteroatom cross-couplings. This research field is dominated by expensive homogeneous noble metal complexes that can only

Asymmetric Active Center Triggers Side‐On Photo‐Fenton‐Like Reaction Through Polar Charge Transfer and Self‐Adapting Sulfur Vacancies

Advanced Science, EarlyView.
The Cu‐Zn3In2S6 photocatalyst (Cu‐ZISV) with asymmetric Cu‐SV‐Zn sites was designed and synthesized to boost peroxymonosulfate (PMS) activation kinetics. The side‐on photo‐Fenton‐like reaction by the asymmetric Cu‐SV‐Zn site accelerated PMS activation and pollutant degradation, and the first‐order kinetic constant of Cu‐ZISV increased by 4.87 times ...
