Abstract Scope |
Bicontinuous nanoporous materials are emerging as a new class of multi-functional materials in view of their large surface areas and superior mechanical rigidity which traditional porous materials, such as metal foams, do not have. Coupled with excellent electric/thermal conductivity and rich surface chemistry for functionalization, the nanoporous materials show great promises for energy and environment related applications. In this presentation I will introduce our recent works in the development of nanoporous metals, metalloids, metallic compounds and 2D materials (graphene and transition metal dichalcogenides) by dealloying, selective phase dissolution and nanoporous metal based chemical vapor deposition. These novel nanoporous materials with 3D nanoarchitecture and tunable surface and electronic structures have been successfully employed as the catalysts, catalytic electrodes and active materials for electrochemical and photoelectrochemical hydrogen production, CO2 reduction, solar energy conversion and high-energy-density batteries. |
