Research Progress of Homogeneous Catalyst for the Dehydrogenation of Formic Acid

Formic acid (HCOOH) has great potential as liquid hydrogen storage materials and for clean hydrogen production. In the past decade, researchers have not only made significant progress in developing more active, stable, and selective catalysts, but also proposed the concept of the reversible system of hydrogen release and storage. This review covers the latest progress of homogeneous catalysts in this field, focusing on the noble metal based catalysts represented by ruthenium, rhodium, and iridium, as well as the non-noble metal based catalysts such as iron, cobalt, nickel, copper, aluminum and so on. It is hoped that this review will provide some insights and idea for developing better catalytic systems for the dehydrogenation of formic acid in the future.
