NaCl Crystal Tuning Nitrogen Self-Doped Porous Graphitic Carbon Nanosheets for Efficient Oxygen Reduction

The demand on the highly efficient and low-cost cathodic electrocatalysts for commercialization of fuel cells is rapidly increasing. One smart route for obtaining these ideal electrocatalysts is extracting active carbon materials from natural and cheap biomass waste. Here, we prepared a novel nitrogen self-doped porous graphitic carbon nanosheets (NPGCNs-NaCl) derived from a nitrogen-rich pruning of Lycium barbarum L. using NaCl crystal as...
