All-Metal Nanoporous Materials as Highly Active Electrocatalysts

该项目旨在为控制良好的大规模合成分级纳米孔铂基结构开辟新的途径，并为所得到的新型电催化剂开发应用。开发新型的高性能、低成本、长寿命的电极催化剂可以提高能量转换技术的效率、成本和耐用性。该项目计划利用定义明确的纳米结构的独特性质来降低铂含量，并提高电催化性能。电催化剂中的纳米孔系统可以提供更多的活性中心和有效的表面渗透性，这应该会提高催化活性。项目成果也有助于我们理解形貌、孔结构、表面原子结构和催化活性之间的关系，以指导其他类型的高性能纳米孔催化剂的开发。

This project aims to create new avenues for well-controlled large-scale synthesis of hierarchical nanoporous platinum-based architectures, and develop applications for the resultant new electrocatalysts. Developing novel high-performance, low-cost, and long-life electrode catalysts can improve the efficiency, cost, and durability of energy conversion technology. The project plans to use the unique properties of well-defined nanoarchitectures to reduce platinum content and to improve electrocatalytic performance. Nanoporous systems in electrocatalysts can provide more active sites and effective surface permeability, which should enhance catalytic activity. Project outcomes may also contribute to our understanding of the relationships among morphologies, pore structures, surface atomic structures and catalytic activities to guide the development of other kinds of high performance nanoporous catalysts.
