Team work: Mesoporous Pt-Ru alloy particles with uniform sizes are synthesized by controlled chemical reduction with ascorbic acid using mesoporous silica as a hard template. Elemental mapping shows uniform distribution of Pt and Ru particles. The electrochemical activity and stability of the alloys towards methanol oxidation much higher than that of mesoporous Pt and commercial Pt catalyst.
团队合作
通过使用介孔硅作为硬模板，用抗坏血酸进行可控化学还原，合成了具有均匀尺寸的介孔 Pt-Ru 合金颗粒。元素映射表明 Pt 和 Ru 颗粒分布均匀。与介孔 Pt 和商业 Pt 催化剂相比，合金对甲醇氧化的电化学活性和稳定性要高得多。
