Abstract

The invention provides a basic cobalt phosphate nanoneedle composite LTON photocatalyst and its preparation method and application. The method first uses a polymerization complexation method and a high-temperature ammonia gas post-treatment method to synthesize LaTiO 2 N; then in LaTiO by hydrothermal method 2 In situ growth of Co on N 3 (OH) 2 (HPO 4 ) 2 Nano-needles, the target product is obtained. The basic cobalt phosphate nanoneedle composite LTON photocatalyst prepared by the invention has a special morphology, and the LaTiO 2 N and Co 3 (OH) 2 (HPO 4 ) 2 A special heterojunction is constructed between the nanoneedles, making Co 3 (OH) 2 (HPO 4 ) 2 Nanoneedle composite LaTiO 2 N photocatalyst compared to pure LaTiO 2 N has better visible light catalytic oxygen production performance, achieving the best performance for pure LaTiO 2 Improvement of N visible light catalytic oxygen production performance.
