Description

technical field [0001] The invention belongs to the technical field of preparation of crystal materials, and in particular relates to a non-alkyl tin oxide cluster compound and its synthesis method and application. Background technique [0002] Tin oxide (SnO 2 ), as an important part of metal oxide materials, has been widely used in transparent electrodes, gas sensors, and solar cells. Recently, many studies have been devoted to the development of SnO 2 Base CO 2 Reductive electrocatalysts, which will help realize carbon-neutral energy cycles with economical and environmental significance. In principle, tin-oxo clusters (TOCs) with precise interfacial structures could be used to target CO at the molecular level 2 The reduction mechanism is experimentally and theoretically understood. Tin oxide clusters (TOCs) as SnO 2 An atomically accurate model of this not only provides opportunities for mechanistic studies but also expands its potential applications through structu...

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.
