Clay-Supported 2-Phenyl-1H-imidazole Derivatives for Heterogeneous Catalysis of Henry Reaction.

Six derivatives of 2-phenyl-1H-imidazole were tested as catalysts of Henry reaction. Two types of catalysis, homogeneous and heterogeneous, were examined and compared. Clay minerals Ca-MMT and Cu-MMT were used as solid supports for ...

Surface oxidation of Ti3C2Tx enhances the catalytic activity of supported platinum nanoparticles in ammonia borane hydrolysis

, MXenes are rarely used in heterogeneous catalysis and, to our knowledge, there are no reports on the use of oxidized MXenes in catalysis. Here we used Ti3C2Tx-derived materials as supports for platinum nanoparticles and s...
