The environmental impact from the waste disposal has been widely concerned around the world. The conversion of wastes to useful resources is important for the sustainable society. As a typical family of wastes, biomass materials basically composed of collagen, protein and lignin are considered as useful resources for recycle and reuse. In recent years, the development of carbon material derived from...
Metal single‐atom catalysts are promising in electrochemical CO2 reduction reaction (CO2RR). The pores and cavities of the supports can promote the exposure of active sites and mass transfer of reactants, hence improve their performance. Here, iron oxalate is added to ZIF‐8 and subsequently form hollow carbon nanocages during calcination. The formation mechanism of the hollow structure is studied...
The growth of lithium (Li) dendrites and the huge volume change are the critical issues for the practical applications of Li‐metal anodes. In this work, a spatial control strategy is proposed to address the above challenges using lotus‐root‐like Ni–Co hollow prisms@carbon fibers (NCH@CFs) as the host. The homogeneously distributed bimetallic Ni–Co particles on the N‐doped carbon fibers serve as nucleation...
