摘要:
The highly dispersed and ultrafine carbon-supported Pd nanoparticles (Pd/C) catalyst is synthesized by using an improved precipitation-reduction method, which involves in Pd-II -> PdO center dot H2O Pd-0 reaction path. In the method, palladium oxide hydrate (PdO center dot H2O) nanoparticles (NPs) with high dispersion is obtained easily by adjusting solution pH in the presence of 1,4-butylenediphosphonic acid (H2O3P-(CH2)(4)-PO3H2, BDPA). After NaBH4 reduction, the resulting Pd/C catalyst possesses high dispersion and small particle size. As a result, the electrochemical measurements indicate that the resulting Pd/C catalyst exhibits significantly high electrochemical active surface area and high electrocatalytic performance for formic acid electrooxidation compared with that prepared by general NaBN4 reduction method.
