Growing three-dimensional biomorphic graphene powders using naturally abundant diatomite templates towards high solution processability

Mass production of high-quality graphene with low cost is the footstone for its widespread practical applications. We present herein a self-limited growth approach for producing graphene powders by a small-methane-flow chemical vapour deposition process on naturally abundant and industrially widely...

This work thus puts forward a practical route for low-cost mass production of various powdery two-dimensional materials.
