Formic acid (HCOOH) is taken as a promising H2 carrier, which has attracted wide concern as a result of high hydrogen content, low toxicity, high stability and simple byproducts. In this paper, we review the catalytic activity of Pd nanoparticles and Pd alloy metal nanoparticles loaded with inert carriers, reduced oxides, metal organic framework materials, carbon materials, as well as molecular sieves. Further, we summarize the reaction mechanism of the HCOOH dehydrogenation reaction driven by thermal energy, photo energy and photo-thermal energy. Finally, we provide the prospects to the challenges faced by HCOOH dehydrogenation reaction from the view of improving the utilization of active metals, using theoretical calculations to deeply understand coupling effects, utilizing advanced techniques to explore reaction mechanisms and realizing carbon cycling.
