Problems solved by technology

However, most of the currently reported TOCs belong to alkyl organotin complexes, which are toxic to human body and cause serious environmental problems.
In addition, since the organic tin source is directly used in the synthesis reaction, and the Sn-C bond is relatively stable, it is difficult to obtain terminal coordination points by breaking the Sn-C bond, and it is also difficult to introduce additional functional organic ligands to modify the tin-oxide cluster.

Embodiment 1

[0039] A kind of synthetic method of non-alkyl tin oxygen cluster compound, concrete steps are as follows:

[0040] Put tin tetrachloride pentahydrate (1.0 mmol) and pyrazole (29.38 mmol) in a 20ml glass bottle, mix well at room temperature, keep constant temperature in a 100 ℃ oven for 4 days, take out, naturally cool to room temperature, and separate the solid phase Rinse with ethanol again to obtain the target product in colorless strip state, with Sn as the reference, the yield is 25%.

Embodiment 2

[0042] Tin tetrachloride pentahydrate (1.0mmol), pyrazole (29.38mmol) and imidazole (2.94mmol) were placed in a 20ml glass bottle, mixed evenly at room temperature, kept at a constant temperature in a 100°C oven for 2 days, taken out, and cooled to room temperature naturally , the solid phase was separated and rinsed with ethanol to obtain the target product in colorless bulk crystalline state. Taking Sn as the reference, the yield was 47%.

Abstract

The invention provides a non-alkyl tin oxide cluster compound, a synthesis method and application thereof, and the molecular formula of the tin oxide cluster compound is C 48 H 56 Cl 12 N 32 O 20 Sn 14 (excluding free molecules), Mr is 3488.30; the tin-oxygen cluster compound is a pure-phase crystalline substance; the crystal system of the tin-oxygen cluster compound is a tetragonal crystal system, and the space group is P- 421c, the unit cell parameter a is b is c is α is 90°, β is 90°, γ is 90°, V is the synthesis method of the cluster compound is simple in process, easy to repeat, low cost of raw materials and easy to produce. Since the non-alkyl tin oxide prepared by the invention has good stability and electrocatalytic carbon dioxide reduction performance, it can be well applied in the fields of environmental protection and the like.

Description

technical field [0001] The invention belongs to the technical field of crystal material preparation, and in particular relates to a non-alkyl tin oxide cluster compound and a synthesis method and application thereof. Background technique [0002] Tin oxide (SnO 2 ) as an important component of metal oxide materials, has been widely used in transparent electrodes, gas sensors and solar cells and other fields. Recently, many studies have been devoted to the development of SnO 2 base CO 2 Reduction electrocatalysts, which will contribute to the realization of a carbon-neutral energy cycle with economical and environmental significance. In principle, tin-oxo clusters (TOCs) with precise interfacial structures can be used to control CO at the molecular level. 2 The reduction mechanism is experimentally and theoretically understood. Tin oxide clusters (TOCs) as SnO 2 Atomically accurate models of , which can not only provide opportunities for mechanistic studies, but also ex...
