Graphene fibers non-woven fabrics (GFFs) are a new type of carbon-based fabrics formed by the overlapping and fusion of graphene fibers, which have good structural stability, flexibility and excellent electrical and thermal properties. However, the pure GFFs are usually poor electrocatalytic without fire-retardant properties due to the dense structure of graphene fibers and few functional groups on the graphene sheet. Here we report a N, P co-doped GFFs (N, P-GFFs) prepared by wet-fusing assembly graphene oxide fibers containing hexachlorocyclotriphosphazene (HCTP) and pyrolysis of the mixture. The introduction of N and P atoms increases the active sites of GFFs, which significantly enhances its electrocatalytic activity, and also makes GFFs with high flame-retardant performance. The newly developed multifunctional refractory nonwoven fabrics are promising great potential in real-world applications.
