چکیده انگلیسی
To fabricate a composite modified with uniformly dispersed metallic particles, in this paper, electrical conductive porous alumina (CPA) was firstly pre-treated with mixed acids followed by deposition of Pt nanoparticles via reductive reaction. Crystal structure of uniformly deposited Pt nanoparticles was confirmed to face centered cubic (fcc). Based on characterization results, selective surface modification was achieved by surface pre-treatment, by which various functional groups were grafted onto three-dimensional conductive networks. The electrochemical behaviors of as-fabricated composites conducted in acidic electrolyte confirmed their improved activities, which merited from novel structure of designed electrode.
