Electrochemical continuous production of supported metal nanocatalysts with high-density step atoms and high activity [PDF]
, 2012 铂族金属是催化、能源、石油化工等领域广泛应用的催化剂。由于铂族金属储量稀少，价格昂贵，如何提高其催化活性、稳定性和利用效率一直是上述领域中的重大关键问题。提高铂金属纳米催化剂的活性和利用率的途径之一是减小催化剂的粒径，并尽可能分散地负载到载体表面。目前，商品碳载铂（Pt/C）催化剂中Pt粒子的尺寸为3nm左右，已基本趋于最优化的尺寸。我们课题组于2007年用电化学方法首次制备出Pt二十四面体纳米晶，开辟了一条调控纳米粒子的表面结构显著提升金属纳米催化剂性能的新途径。Pt二十四面体纳米晶由{730 ...

, 2014 具有明确表面结构的纳米晶催化剂在Pt单晶面模型催化剂(二维宏观尺度)与实际纳米催化剂(三维纳米尺度)之间架起了桥梁以跨越两者存在维度和尺度上的巨大鸿沟。相比于低指数晶面，具有低配位台阶原子的Pt高指数晶面单晶电极对有机小分子电氧化具有更高的催化活性。由{730}晶面围成的具有高台阶原子密度、开放结构的Pt二十四面体纳米晶对甲酸、乙醇表现出较好的催化活性。有机小分子电氧化是结构敏感的反应常会解离生成吸附态的CO(COads)，虽然有机小分子在铂单晶模型电催化剂上得到大量研究 ...
