Description
Technical Field
The invention belongs to the technical field of micro-nano material preparation, and particularly relates to a preparation method of fourteen-surface cuprous oxide and the fourteen-surface cuprous oxide prepared by the preparation method.
Background
Cuprous oxide is a typical p-type semiconductor with a forbidden band width of 2-2.2 ev, and has good photoelectric properties and is applied to various fields. For example, the cuprous oxide nanowire is used as a photocathode to crack water to produce hydrogen; the cuprous oxide 50 surface body is used as an oxidation catalyst for catalyzing hydrogen generation by carbon monoxide. Huang's group [ JAm Chen Soc,2012,134 (2): 1261-1267] successfully synthesizes cubic, octahedral, rhombic dodecahedral, truncated dodecahedral cuprous oxide materials, and the study also proves that exposure of specific crystal faces has a key effect on the catalytic performance of the materials, and the catalytic reaction process is mainly influenced by the density of copper atoms on the surfaces of the materials. Similarly, pang et al [ CrystEngComm,2010,12 (2): 406-412] synthesized a series of cuprous oxide crystallites by a glycine-assisted double solvothermal reaction, and researches show that the catalytic properties of cuprous oxide are mainly influenced by the morphology of the cuprous oxide crystallites, so that the design and synthesis of cuprous oxide with special morphology is of great significance in the future catalytic field.
Theoretically, cuprous oxide with a specific crystal face is beneficial to improving the photocatalytic performance of the cuprous oxide. Geng Wangchang et al [ CN109485085A ] prepared hollow octahedral cuprous oxide using glucose and alkaline solution, tao Feifei et al prepared cubic cuprous oxide using anhydrous sodium acetate and anhydrous glucose. Li Yadong copper nitrate is used as copper source, potassium borohydride is used as reducing agent, and nanospheres with the diameter of about 250nm are obtained in an oil bath, but the surface is smooth, so that the specific surface area is relatively small. Sun Zuosong et al prepared a twenty-hexahedral cuprous oxide crystal by adding an additive to an organic solvent. In hexahedral cuprous oxide, the preferentially exposed crystal face is {100}, and in octahedral cuprous oxide, the preferentially exposed crystal face is {111}. Typically the (100) crystal plane has a lower surface energy than the (111) crystal plane. Thus, cuprous oxide spontaneously tends to form a hexahedron exposing {100 }. The surface energy of the {111} crystal plane group can be reduced by the crystal plane control agent to be lower than the energy of the {100} crystal plane group and exposed, so that an octahedral morphology can be formed. However, nucleation and growth kinetics during crystal growth are also affected by factors such as temperature, precursor concentration, etc. Thus, there is a great challenge to simultaneously expose fourteen planes having similar proportions of {100} and {111} planes. The cuprous oxide crystal with the morphology of fourteen planes is successfully prepared by controlling the proper reaction dynamics conditions.
Based on the analysis, a preparation method capable of producing uniform fourteen-surface cuprous oxide is urgently needed in the industry at present.
