摘　　要：In this work, we fabricated the poly（N-vinyl-2-pyrrolidone） （PVP）-stabilized ruthenium（0） nanoclusters by reduction of RuC13 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 （NaBH4） exhibited highest catalytic activity for the decomposition of formic acid into H2 and CO2. The turnover of numenber （TOF） value could reach 26113 h-1 at 80 ℃. We believe that the effective catalysts have potential of application in hydrogen storage by formic acid.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.
