Embodiment Construction

[0011] We have selected silver iodide and dibenzothiazole disulfide as the reaction raw materials, and ethanol and hydroiodic acid are both as the reaction raw materials and as the solvent, and the compound (Et 2 mbt)Ag 2 I 3 single crystal. Organic components (Et 2 mbt) 2+ It is generated in situ from the raw material dibenzothiazole disulfide. The property tests of the compounds showed that the properties of the organic and inorganic components were well preserved in the compound (Et 2 mbt)Ag 2 I 3 middle.

[0012] The idea of ​​reducing the Ag content in the AgI semiconductor catalytic material provided by the invention is simple, easy to operate, sufficient source of raw materials, and low synthesis cost.

[0013] The AgI-based inorganic-organic hybrid semiconductor photocatalytic material prepared by the invention effectively retains the excellent performance of the inorganic components, has a good photocatalytic degradation ability of methyl orange dye, and can u...

Abstract

The invention relates to an AgI-based inorganic-organic hybrid semi conducting material synthesis and an application for photocatalytic degradation of a dye. A purpose of the present invention is synthesis of an inorganic-organic hybrid semi conducting material (Et2mbt)Ag2I3 capable of effectively catalyzing and degrading a methyl orange dye, wherein Et is ethyl; mbt is 2-mercaptobenzothiazole. According to the invention, organic molecules containing N and S elements are introduced in inorganic AgI, so that inorganic AgI performance can be kept, and Ag content can be reduced. In the invention, silver iodide, dibenzothiazyl disulfide, ethanol and hydroiodic acid are taken as the reaction raw materials, and monocrystalline of the compound (Et2mbt)Ag2I3 can be obtained under heat condition of a solvent. According to the invention, excellent photocatalysis performance of the hybrid semi conducting material can be used for degradation of methyl orange pollutant in life and industrial sewage, and the semiconductor performance of the hybrid semi conducting material can be used for manufacturaing the semiconductor devices.

Description

technical field [0001] The invention relates to a molecular-based inorganic-organic hybrid semiconductor photocatalytic material, in particular to an AgI-based inorganic-organic hybrid semiconductor material (Et 2 mbt)Ag 2 I 3 The synthesis and application of Et = ethyl; mbt = 2-mercaptobenzothiazole. Background technique [0002] my country is a country seriously short of water resources, and the total amount of fresh water resources in our country is 2.8 trillion m 3 , accounting for 6% of the world's water resources, ranking fourth in the world. However, due to my country's large population base, the per capita water resources are very low, only 1 / 4 of the world's average level, and it is the poorest per capita water resources in the world. one of the countries. Therefore, while saving water, it is of great practical significance to study the degradation treatment technology of domestic and industrial sewage, so as to turn waste into treasure, purify it into non-toxic,...
