Abstract

The invention provides an attapulgite / C 2 The preparation method of N1D / 2D composite materials, using in-situ chemical reaction to combine 2D C 2 A thin layer of N loaded on the surface of one-dimensional attapulgite can effectively suppress C 2 N thin layers re-aggregated to effectively expose the active sites while increasing their specific surface area, resulting in a novel attapulgite / C with excellent optical and electrical properties 2 N 1D / 2D composite materials.

Description

technical field [0001] The invention belongs to the field of new materials, in particular to an attapulgite / C 2 Preparation method of N one-dimensional / two-dimensional composite materials. Background technique [0002] In recent years, carbonitride-based nanostructured materials have attracted great attention in the field of photocatalytic water splitting due to their abundant resources, good thermal and chemical stability, adjustable electronic structure, non-toxic and harmless, and low cost. s concern [13,14] . where C 2 N is the latest reported graphite-like carbon nitride, which has a two-dimensional layered structure, and theoretical predictions show that its band gap is 1.96 eV. in C 2 In the two-dimensional thin-layer planar structure of N, there are periodic small holes, and the boundaries of the holes are composed of nitrogen atoms, resulting in the enrichment of electrons in nitrogen atoms; and C 2 The force between the N sheets is weak, and it has the charac...
