Platinum(Pt)catalysts modified by other suitable metals significantly enhance their electrochemical activities for formic acid oxidation.In this work,a titanium-supported nanoporous network platinum(nano Pt/Ti)electrode was prepared using a hydrothermal method.The as-prepared nano Pt/Ti electrode was modified with a certain amount of lead by using cyclic voltammetry for different scan cycle numbers(n),namely,n=10,15,20 and 30,to synthesize the novel lead-modified nanoporous Pt(nano Pb_((n))-Pt/Ti)electrodes...
