Abstract:Sm3+ doped SiO2@TiO2 nanospheres with diverse morphology have been successfully prepared. The size of SiO2 could be adjusted not only by changing the etching time but also through varying the coating method of TiO2. Sol‐gel and solvothermal methods were adopted to investigate the effect of coating conditions on morphology and properties of the products. Photocatalytic results showed that core‐shell structures obtained by solvothermal method possess the highest photodegradation efficiency, which reached 98% for… Show more
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.
