Description
Summary:Developing low cost and efficient anode and cathode materials toward electrocatalysis are regarded as one of the most desirable yet challenging research directions, which are intimately related to the pressing energy, environmental and human health issues. Currently, 3 D foam (such as Ni foam, Cu foam, and graphene foam) based heterogeneous catalysts have been intensively explored for actively catalyzing the electrode reactions. Their inherent characteristics of stereo‐network structure, high specific area and large pore volume not only provide better mass transport of reactants to electrode surfaces, but also pave 3 D electron transport pathways. Herein, recent significant progress and rational design of foam‐based electrocatalysts are reviewed. In addition, some insights into current challenges and future directions of foams for efficient electrocatalysis are proposed and discussed. Foam is versatile: 3 D foam based heterogeneous catalysts have been explored to catalyze various electrochemical reactions. This review outlines recent progress of design and application of foam for electrocatalysis. Current challenges and future research directions are also discussed.
