| titleOfInvention | Preparation method of visible light photocatalyst with tight connection |
| abstract | The invention belongs to the field of preparation of photocatalysts, in particular to a preparation method of a visible light photocatalyst with close connection, which solves the problem that pure g-C is adopted at present 3 N 4 The photocatalyst has the technical problems of low catalytic activity, narrow spectral response range and CdS photo-corrosion. The invention comprises the following steps: (1) g-C 3 N 4 The material is synthesized by a high-temperature thermal polymerization method with melamine as a precursor; (2) the hollow microsphere CdS is synthesized by a hydrothermal method by taking thiourea as a sulfur source; (3) CdS/g-C 3 N 4 The composite photocatalyst is synthesized by a low-temperature calcination method. The invention provides CdS/g-C 3 N 4 The composite photocatalyst can realize high-efficiency degradation of organic pollutants, has good settling property and is beneficial to separation and recovery of the composite photocatalyst. Because the two are closely connected, the separation and transfer of photo-generated charges at the connecting interface of the composite photocatalyst can be accelerated, the photocatalytic activity of the composite photocatalyst is enhanced, and the cycle stability of the composite photocatalyst is improved. |
