The cover picture shows the construction of interfacial inorganic nanostructures and their application in electrocatalysis. In this review, we begin with the controllable synthesis of three classic configurations on interfacial nanostructured materials by briefly introducing some recent advances in interfacial engineering. More importantly, we concentrate on several typical model studies of inorganic heterogeneous nanostructured electrocatalysts for different energy conversion reactions, due to the special interface and synergistic effect. More details are discussed in the article by Xi et al. on page 772–782.
