A highly active and stable palladium catalyst on a g-C3N4 support for direct formic acid synthesis under neutral conditions

Abstract

Graphitic carbon nitride (g-C3N4) is applied as a support of the Pd catalyst for direct HCOOH synthesis by CO2 hydrogenation under neutral conditions. The high CO2 affinity of g-C3N4 is responsible for the enhanced catalytic activity and stability relative to the inert support such as a carbon nanotube.
