Lactose, the characteristic carbohydrate of milk, is a high-value product applied as an excipient in pharmaceutical formulations and as a carrier in dry-powder inhalers when purified. Usually, lactose is in...
Preparation of ZnWO4/Cu2O composite materials by environmental protection experimental method. ZnWO4 nanorods were prepared by a simple hydrothermal method, and then ZnWO4/Cu2O composites were prepared by chemical precipitation method. The experimental method is simple and clean. Due to the unique structural characteristics of Cu2O, the wide band gap of ZnWO4 was improved and the ZnWO4/Cu2O composite with better catalytic performance was generated. Various tests show that the catalytic performance and stability of ZnWO4/Cu2O is not lower than that of ZnWO4. Among them, ZnWO4/Cu2O-5 has the best catalytic degradation effect. The Cu-H generated during the degradation of 4-nitrophenol (4-NP) prevents the oxidation of Cu+, and the neutral product 4-aminophenol (4-AP) is easier to fall off, which improves its recycling efficiency. These encouraging results show that the ZnWO4/Cu2O composites have great potential to degrade 4-NP.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
