This paper describes a novel process which is used to prepare well-dispersed Pt nanoparticles on zeolitic imidazolate framework-90(ZIF-90).The electrocatalytic activity of Pt/CN is evaluated by cyclic voltammetry(CV).Compared with the commercial Pt/C catalyst,the so-prepared Pt/CN composite materials show higher electrotrocatalytic cativity.These properties recommend Pt nanoparticles-functionalized ZIF-90 as a promising catalyst for direct methanol fuel cells.
