Problems solved by technology

However, the current research mainly focuses on the composite energy band regulation and microscopic morphology construction of graphene and carbon nitride, and there are few reports on the assembly form and related large-scale preparation of the two macroscopic materials.
Moreover, contemporary society has higher and higher requirements for portable devices. How to obtain light-weight, durable and easy-to-storage photocatalytic devices is also the current bottleneck.

Abstract

The invention discloses a metal-loaded carbon-nitride-doped graphene-based flexible non-woven fabric and a preparation method and application thereof. The method includes the following steps of injecting graphene oxide dispersion liquid into a coagulating bath with a certain amount of metal ions to obtain cross-linked gel fiber, using a swelling-fusing effect to obtain a graphene oxide non-woven fabric with metal ions, and then using a chemical vapor deposition method to generate metal-doped carbon nitride on the non-woven fabric in situ so as to obtain the metal-loaded carbon-nitride-doped graphene-based flexible non-woven fabric. The non-woven fabric has a certain bending-resistant property, has a quite high light response activity, and has a wide application prospect in a visual light catalysis field. The non-woven fabric promotes actual application of a graphene-based material, expands a photocatalysis device preparation method, and provides beneficial assistance for developing portable photocatalysis devices.
