Preparation of Pd-Pt alloy nanowire by potentiostatic pulse electrodeposition method and its hydrogen absorption properties

In chemical production,the in situ rapid accurate and quantitative monitoring of hydrogen has important significance for safety production because of its inflammable and explosive properties.In the study,we first prepared the Pd-Pt alloy nanowires with AAO as the template by potentiostatic pulse electrodeposition in the solutions of 0.2 mol/L H3BO3 containing 60 mmol/L PdCl2 and 40 mmol/L H2PtCl6·6H2O with pH value of 5.9.For pulsed electrodeposition,rectangular potential pulses were used.During each pulse,a potential of-0.4 V versus SCE was applied for 1 s,followed by a potential of 0 V versus SCE being applied for 3 s,with the effective electrodeposition time of 2 h.The energy spectrum suggested content of Pt was approximately 30%.
