A Borocarbonitride Ceramic Aerogel for Photoredox Catalysis
Angewandte Chemie - International Edition, 2019AbstractBorocarbonitride (BCN) is a new type of photocatalyst, but bulk BCN shows a large band gap, and low surface area, and moderate activity for photocatalysis. Here, a three‐dimensional (3D) porous ceramic BCN aerogel was developed as an effective photocatalyst for relevant reactions.

Metal‐Free Carbonylations by Photoredox Catalysis
Angewandte Chemie International Edition, 2014AbstractThe synthesis of benzoates from aryl electrophiles and carbon monoxide is a prime example of a transition‐metal‐catalyzed carbonylation reaction which is widely applied in research and industrial processes. Such reactions proceed in the presence of Pd or Ni catalysts, suitable ligands, and stoichiometric bases.
