  • Publication number: 20230192555
    Abstract: The present invention discloses a nitrogen-sulfur co-doped Ti3C2-MXene nanosheet and a preparation method and application thereof. Ti3C2-MXene is obtained by etching ternary layered carbides of MAX phase through hydrofluoric acid; and then, the nitrogen-sulfur co-doped Ti3C2-MXene nanosheet is synthesized by a simple one-step method by taking thiourea as a heteroatom source. The nitrogen-sulfur co-doped Ti3C2-MXene nanosheet has a unique two-dimensional layered structure, large specific surface area and abundant heteroatomic catalytic activity sites so that the material presents excellent peroxidase-like activity. The method of the present invention can successfully dope two elements of nitrogen and sulfur in one step on Ti3C2-MXene, and can effectively overcome the tedious problem of a step-by-step doping step and the secondary pollution problem of different doping sources to endow peroxidase-like activity for Ti3C2-MXene.
