Description	Journal: Nanotechnology Engineering of electrocatalysts with high performance for cathodic and/or anodic catalytic reactions is of significant urgency for the development of direct methanol fuel cells. Pt-based bimetallic alloys have recently received considerable attentions in the field of fuel cells because of their superior catalytic performance toward both fuel molecule electro-oxidation and oxygen reduction. In this work, bimetallic PtCo mesoporous nanospheres (PtCo MNs) with uniform size and morphology have been prepared by a one-step method in a high yield. The as-made PtCo MNs show superior catalytic activities for both oxygen reduction reaction and methanol oxidation reaction relative to Pt mesoporous nanospheres (Pt MNs) and commercial Pt/C catalyst, attributed to its mesoporous structure and bimetallic compositions.
