Since the discovery of continuous oxidation on the surface of TiO2 can occur in the water reduction reaction,photocatalytic materials as the representative has been studied extensively.In this experiment,the TiO2 nanotubes were prepared by hydrothermal synthesis method,on the formation of the nanotubes were characterized and analyzed.Nano and prepared for the tube photocatalytic reduction of CO2 solution to produce methanol,successfully simulated the organism photosynthetic CO2 fixation.Forefront of the development of this research based on CO2 this topic on photocatalytic reduction,TiO2 nanotubes for photocatalytic water solution of CO2 reduction,thus the preparation of methanol is an important chemical product,provides a new way for the utilization of CO2.At the same time,through the analysis of the prepared nanotube aqueous solution of CO2 reduction to produce methanol effect,explore the effect factors of the catalytic effect,catalytic reaction mechanism of the reduction process,has carried on the beneficial exploration enrich the theoretical system of photocatalytic reaction.And the TiO2 photocatalytic prospect
