In this work, we fabricated the poly(N-vinyl-2-pyrrolidone)(PVP)-stabilized ruthenium(0) nanoclusters by reduction of RuCl_3 using different reducing agents, and studied their catalytic activity in hydrogen generation from the decomposition of formic acid.It was demonstrated that N-vinyl-2-pyrrolidone(NVP), which is a monomer of PVP, could promote the reaction by coordination with Ru nanoparticles. The Ru nanoparticles catalyst reduced by sodium borohydride(NaBH_4) exhibited highest catalytic activity for the decomposition of formic acid into H_2 and CO_2. The turnover of numenber(TOF) value could reach 26113 h~(–1) at 80 °C. We believe that the effective catalysts have potential of application in hydrogen storage by formic acid.

The turnover of numenber (TOF) value could reach 26113 h ~ (-1) at 80 ° C. We believe that the effective catalysts have potential of application in hydrogen storage by formic acid.
