Problems solved by technology

[0003] At present, the research on photocatalytic degradation of organic dye wastewater mainly focuses on oxygen-containing semiconductor photocatalysts such as titanium dioxide and zinc oxide. However, these catalysts tend to form stable intermediates during the degradation of some organic dyes and cannot be completely degraded. Organic dyes, therefore, it is necessary to prepare and optimize new catalysts according to the photocatalytic degradation mechanism of different types of organic pollutants
In addition, oxygen-containing semiconductor photocatalysts generally have a large band gap (for example, the band gaps of titanium dioxide and zinc oxide are 3.20eV and 3.37eV, respectively), and only in the ultraviolet range (less than 5% of the total solar energy) Responsive, but non-responsive in the visible light range (about 43% of the total solar energy), which greatly limits their photocatalytic applications under visible light irradiation

Embodiment 1

[0022] 1. Compound Preparation

[0023] InCl 3 0.0179g (0.07936mmol), Te0.0057g (0.04467mmol), MgCl 2 ·6H 2 O0.0206g (0.1015mmol) and 3ml of diethylenetriamine were added to a hard glass tube, and the two ends of the glass tube were sealed. Keep at 170°C for 7 days, then cool down to room temperature naturally. Blocky crystals appeared. The crystal sample was taken out, washed with ethanol three times, and dried in a desiccator to obtain 0.0390 g of diethylenetriamine monohydrate indium telluride crystal. Yield 40% (based on tellurium).

Description

technical field [0001] The invention relates to a compound with photocatalytic performance and its preparation, in particular to an organic hybrid telluride with photocatalytic performance and its preparation. Background technique [0002] Since Japanese scholars Fujishima and Honda discovered in 1972 that titanium dioxide photocatalysts can actually split water to produce hydrogen, people have been interested in photocatalytic technology. Photocatalytic technology not only shows attractive applications in photocatalytic decomposition of water to produce hydrogen and photocatalytic reduction of carbon dioxide to prepare organic matter, but also it is a new type of modern environmental pollution control technology, because it has obvious effects on the main organic pollutants in the environment. Excellent degradation effect, easy control of operating conditions, strong oxidation ability, no secondary pollution, has obvious advantages. Therefore, photocatalysts with photocata...
