Abstract

Hierarchically porous films as catalysts or supports are fascinating electrode materials for the electrochemical conversion and storage of energy due to the short transportation paths of electrons and ions. A novel and feasible method to construct 3D porous films is developed by direct electrodeposition on a gas–liquid–solid (GLS) three-phase interface. The formation mechanism of the porous structure is discussed based on bubble behavior and electrocrystallization. The progress toward the preparation of porous metals/alloys on cathodes and metal oxides/polymers on anodes is reviewed. The surface decoration of porous metal films by noble metals or non-metal compounds is summarized. The promising energy applications of porous films are highlighted.
