The Development of Better Photocatalysts through Composition- and Structure-Engineering

Semiconductor photocatalysts that can effectively utilize solar irradiation hold great potential for harnessing renewable-energy sources, as well as for environmental protection and -remediation. Exploring advanced photocatalysts that have improved performance has been a central theme in photocatalysis research. Herein, we review the recent developments in the design-and fabrication of photocatalysts with an emphasis on composition-and structural control over multiple length scales. This Focus Review will be of value for researchers in the area of photocatalysis, in particular, in the aspects of material design that lead to the synthesis of better photocatalysts.
