摘要

The quickly expanded energy consumption based on traditional fossil fuels has resulted in energy crises and severe environmental problems.Developing sustainable energy conversion technology is an important issue confronting the global energy security and consumption.Electrochemical energy storage and conversion is one of the most perspective renewable ways to produce carbon-free fuels via water splitting, and convert chemicals into electricity by fuel cells and metal-air batteries.A recent class of porous materials,metal-organic frameworks (MOFs), has been extensively explored as electrocatalysts or precursors to derive efficient composites in virtue of their large surface area, high porosity,tunable structures, and uniform dispersion of components [1].Because most MOFs are formed by inexpensive transition metals and commercial organic ligands, they have been regarded as promising earth-abundant electrocatalyst alternatives to conventional expensive benchmark noble-metalbased materials (Figure 1).
