摘      要：The synthesis of nanocrystals(NCs)with defined morphology and surface structure provides an effective way to investigate the structure-activity relationship of nanocatalytsts,and it will facilitate the design of nanocatalysts with excellent catalytic *** this paper,we developed a facile method to synthesize PdH0.43 NCs with the shape of cube,octahedron and rhombic dodecahedron(RD),whose surface facets are{100},{111}and{110},*** asprepared PdH0.43 NCs are highly stable and exhibit enhanced catalytic activity and extremely low overpotential towards electro-oxidation of formic acid compared with the commercial Pd black and three types of Pd *** specific activity of the cubic PdH0.43 NCs is more than five times that of the commercial Pd black and two times that of the cubic Pd *** the three types of PdH0.43 NCs with different surface structure,the activity order is followed by PdH0.43{100}PdH0.43{111}PdH0.43{110}.
