Abstract

The invention provides an activated carbon loaded cuprous oxide photocatalyst, which can be used for degradation of organic pollutants such as phenols, purification of air and organic synthesis of epoxidation of alkenes. The activated carbon loaded cuprous oxide photocatalyst is prepared by reducing surface modified activated carbon as well as room temperature solid phase copper sulfate and sodium hydroxide by C6O12O6 under the action of a bit of initiator also serving as a protective agent so as to have room temperature solid phase self-propagating reaction. According to the preparation of the activated carbon loaded cuprous oxide visible light photocatalyst, copper sulfate is taken as the raw material, activated carbon is taken as a carrier, and the activated carbon is loaded with cuprous oxide through solid phase self-propagating reaction at room temperature. The catalyst has a simple, convenient and economical preparation method, and has good stability and high photocatalytic activity. The catalyst can be used for catalytic oxidation of phenol waste water, purification of indoor aldehyde air, and epoxidation organic synthesis of alkenes, can be directly used under the ultraviolet-visible light condition, is easy to operate, has mild reaction conditions, has a high pollutant removal rate, and has good selectivity in organic synthesis.
