Barrier is reacted, all kinds of catalyst materials are widely used in electroreduction carbon dioxide reaction process, to accelerate reaction rate.
It in recent years, is the New Two Dimensional nano material of representative because of its unique structure and excellent electrochemistry using graphene
Can, it is widely used in energy catalytic field.Two-dimension nano materials can promote electro-catalysis anti-with its high specific surface area
High-efficient contact during answering between catalytic media, to realize, quick charge transfer provides guarantee between interface, to be expected to
It designs to obtain the electroreduction carbon dioxide reaction catalyst of Cheap highly effective by specific structure based on this.As a special dictionary
The two-dimension nano materials of type, two-dimentional In2S3Nanometer sheet largely exposed active site and is being urged with its unique architectural characteristic
Good stability causes the interest of more and more researchers during change.Meanwhile the electronic structure of catalyst is in electroreduction
Also have the function of during carbon dioxide reaction particularly important.Excellent electronic structure can improve the absorption to gas molecule
Ability adjusts the adsorption strength that differential responses intermediate in interface is catalyzed during electrocatalytic reaction, so that it is guaranteed that efficiently
Journal of Molecular Catalysis transformation efficiency.And the property of nano material and the structure of catalyst, surface topography and component are closely bound up, therefore,
It how probes by two-dimentional In2S3The regulation of nanometer sheet electronic structure realizes it for CO2The active promotion of Journal of Molecular Catalysis has
Very important meaning.

Property；In addition, " German applied chemistry " (Angewandte Chemie International Edition57,6054-6059,
2018) it reports, introduces Lacking oxygen and the electronics near valence band is caused to increase, electronic transfer process is promoted, to promote
Oxygen-enriched defect ZnO nano on piece electroreduction CO2To CO product.These methods are focused on by interface or surface defect
Reason improves catalytic activity, needs to use the noble metal catalysts such as Au and preparation process is complicated, while being also required to special installation
And instrument is unfavorable for large scale preparation, and electronic-controlled effect is limited, needs to find accuracy controlling so that reaction cost is very high
The regulation method of component.
Up to the present, there has been no document reports under simple condition, and quick magnanimity is prepared ingredient controllable precise, is had
