燃料电池因其环保高效受到工业、交通等领域的青睐。铂是燃料电池重要的催化剂，但铂储量少且价格昂贵，提高铂基催化剂的活性和降低铂用量成为研究热点。我们课题组在2nm左右铂纳米线催化剂方面做了有益探索（JACS, 2012），最近国内外科学家聚焦亚纳米电催化剂合成，特别指出材料特征尺寸小于1nm时表面原子比例接近100%，催化性能会极大提高。本项目将致力于长度达微米级直径小于1nm的铂基合金纳米线、亚纳米(sub-1 nm)铂基合金外壳核壳结构纳米线，亚纳米管壁铂基合金纳米管的合成。利用类淀粉蛋白稳定的纤维化特性控制合成形貌均匀的一维铂基合金催化剂。通过合金化降低铂的用量，通过亚纳米化提高其催化活性。研究合金元素的影响规律以及多元掺杂时的协同效应。通过氧还原、甲醇氧化等测试及材料的组分结构等表征，探究其生长机理、亚纳米尺度电催化性能的控制规律，将催化剂的活性和稳定性提高到新高度。

Fuel cells are favored by industry, transportation and other fields because of their environmental efficiency. Platinum is an important catalyst for fuel cell, but the platinum reserves are low and the price is expensive. Our team has made beneficial exploration for around 2 nm platinum nanowires catalyst (JACS, 2012). More recently, scientists both at home and abroad focus on the nanometer catalyst synthesis, especially point out that surface atomic ratio is close to 100% in the material size less than 1 nm. These materials can greatly improve the catalytic performance. This project will aim to length up to micron level and less than 1 nm in diameter platinum alloy nanowires, and subnanometer (sub-1nm) platinum-based alloy shell nanowires core-shell structure, and the synthesis of subnanometer platinum-based alloy tube wall nanotubes. A one-dimensional platinum-based alloy catalyst with uniform morphology will be controlled by the stable fibrosis properties of the amyloid protein. Reducing the amount of platinum by alloying, the catalytic activity can be improved by subnanometer. The influence rule of alloy element and the synergistic effect of multivariate doping are studied. By oxygen reduction and methanol oxidation test and material composition structure characterization, we explore its growth mechanism, the control law of nanoscale electric catalytic properties. The catalysts with high activity and stability will be obtained.
