Abstract

See full text

Disclosed herein are methods of producing photocatalysts for degrading NOx. According to some embodiments of the present disclosure, the method comprises mixing a transitional metal or its oxide with a bone powder or a shell powder, followed by heating the mixture for a least 12 hours to dehydrate the mixture, and calcinating the dehydrated product for 1-5 hours. Also disclosed herein are methods of degrading NOx by using the thus-produced photocatalysts. Materials used doped with the transitional metal or its oxide are bone powder and shell powder, which is derived from animals (a chicken, a cow, a pig, a duck, a sheep, a donkey, or a horse) and shells from different species of sea water (a shrimp, a crab, a clam, a barnacle, a snail, an abalone, or an oyster), respectively.
