Solution Grown Nanostructured Ceramic Coatings for Photocatalytic and Antibacterial Surface

摘要

Low-temperature solution growth of ceramic coatings provides unique opportunities for tailoring surface functionalities of base materials.It also enables the coating to be made on the surface of materials that mav not survive high processing temperatures.In this smdy.we fabricated a functional surface made of nanostrucmred coatings of TiO2 and ZnO via a hydrothermal method.In particular.TiO2(anatase)nanotexmred clusters and ZnO nanorods exhibited the ability to decompose organic dyes and toxic species,and also to inactivate harmful bacteria.To further explore a more effective way of using such a functional surface,we processed a'core-shell'structure consisting of a rutile nanorod core and a functionalized shell layer.Such hybrid structure exhibited a strong photocatalytic surface,thereby providing the opportunities for more targeted functional properties.
