  • Atomically Dispersed Co Atoms Stabilized by Nitrogen Species in Carbon Skeleton for Efficient Oxygen Reduction and Zn-air Batteries

    Rongrong Liu, Jizheng Feng, Tao Meng

    Atomically dispersed and nitrogen-coordinated single metal atom implanted into the carbon substrate holds great promise as Pt-liked catalysts for oxygen reduction reaction (ORR). However, the complicated synthetic procedures of single atomic catalysts heavily limit their widespread applications. Herein, the atomically dispersed Co stabilized by nitrogen species in carbon skeleton (Co-SAs/NC) is prepared by a controllable pyrolysis of the nano-confined Co-precursor, and further employed as alkaline ORR catalyst. The atomic configuration and electronic structure of Co-SAs/NC are systematic investigated by a wide range of advanced techniques, such as electron microscopic and X-ray absorption spectroscopy. As expected, Co-SAs/NC exhibites excellent ORR activity with a large onset and half-wave potentials, as well as good selectivity and favorable stability. More importantly, the outstanding ORR performances of Co-SAs/NC enable the assembled Zn-air battery to deliver a large specific capacity of 788.4 mAh•gZn-1, a maximum power density of 233.6 mW•cm-2, and a long cycle life.

  • Biomass-Derived Porous Carbon: Synthesis and Application for Energy Conversion and Storage

    Hong Liu, Shuai Liu, Lei Liu

    The conversion of biomass to carbonaceous materials have received wide attention these years. In particular, biomass-derived carbons demonstrate great potential as electrodes for different energy storage system due to their various architectures, low cost, and renewability. This review provided the recent progress in the synthesis and application of biomass-derived carbons and their hybrids as electrodes for energy storage. Various carbon structures including spheres, 1D fiber/tube, 2D sheets, 3D hierarchical porous carbon have been acquired from various biomass through different activation methods. Owing to their devise composition and morphology, the biomass-derived carbon materials are employed as electrodes for supercapacitors, metal-ion batteries and Li-S batteries. Finally, conclusions and outlook trends to the future development of biomass-derived carbons are proposed.
