Problems solved by technology

[0003] For a long time, research on photocatalytic degradation of organic dye wastewater has mainly focused on oxygen-containing semiconductor photocatalysts, which generally have a large bandgap (bandgap greater than 3.0eV), and only in the ultraviolet range (less than the total sunlight). 5% of the energy), but no response in the visible light range (about 43% of the total energy of sunlight), which greatly limits their photocatalytic applications under visible light irradiation

Embodiment 1

[0022] 1. A preparation of organic hybrid manganese stannate:

[0023] SnCl 4 ·5H 2 O (0.0150g, 0.04mmol), Mn (0.0171g, 0.31mmol), Se (0.0161g, 0.20mmol) and 2ml of ethanolamine were added to the hard glass tube, and the two ends of the glass tube were sealed. Keep it under the condition of 170 degrees Celsius for 7 days, then cool down to room temperature naturally. Orange blocky crystals appeared. The crystal samples were taken out, washed 3 times with ethanol, and dried in a desiccator. Yield 52%.

[0024] 2. Confirmation of compounds

[0025] The prepared six (ethanolamine anion) combined two (selenostannoic acid) heptamanganese crystals were placed on the Bruke smart APEXIIICCD diffractometer, and the Mo Kα (λ=0.071073nm) ray monochromated with a graphite monochromator was used to measure ω-θ way to scan. At 173K, a total of 18417 diffraction spots were collected. By the full matrix least squares method for F 2 The modified structural analysis was done with the S...

Abstract

The invention discloses organic hybrid (Mn7(ea)6(SnSe4)2)n and a preparation method thereof. Organic hybrid (Mn7(ea)6(SnSe4)2)n is chemically named as hexa(ethanolamine anion)bis(selenostannate) heptamanganese and is prepared from SnCl4.5H2O, Mn and Se as raw materials. Organic hybrid (Mn7(ea)6(SnSe4)2)n has the advantages of easily available raw materials, simple process, high yield, good repeatability and the like, and is not susceptible to dissolving in common solvents.

Description

technical field [0001] The invention belongs to the technical field of organic heterocompounds. Specifically relates to an organic hybrid manganese selenide stannate and a preparation method thereof. Background technique [0002] Photocatalytic technology is a green technology with important application prospects in the field of energy and the environment. It not only shows attractive applications in the photocatalytic water splitting to produce hydrogen and photocatalytic reduction of carbon dioxide to prepare organic matter, but also it has great impact on the main organic matter in the environment. The pollutants have obvious degradation effect, the operating conditions are easy to control, the oxidation ability is strong, and there is no secondary pollution, which has obvious advantages. Therefore, catalysts with photocatalytic activity have important applications in pesticide removal, automobile exhaust treatment, photochemical conversion, dye treatment, air purificati...
