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.Read moreRead less
