Hierarchical Mesoporous Materials for Energy Conversion and Storage XIAOCHANGLONG 2019 The aim of this project is to develop hierarchical and mesoporous materials based on earth-abundant transition metals via a variety of technologies including templating, hydrothermal approaches, electrodeposition and solution-based methods. The project seeks to exploit the high surface area of the materials, synergistic effects and morphology control to produce catalysts with excellent performance in chemical reactions that are relevant for energy conversion and storage including hydrogen production, ammonia synthesis and supercapacitors.
