Microfluidics-enabled Rational Design for Ag-ZnO Nanocomposite Films for Enhanced Photoelectrochemical Performance

Abstract

Ag-ZnO nanocomposite film has been widely employed as a promising photocatalyst displaying the excellent charge separation and broadband absorption under illumination. Although a variety of synthetic methods have been proposed, the preparation of the nanocomposite film with controlled morphology in a single process has been rarely attempted. Here, we introduce a facile and rapid synthetic method to fabricate the Ag-ZnO nanocomposite films with controlled morphology by using microreactor-assisted solution deposition (MASD) process. The nanocomposite film could be formed in a single process within 10 min, which is enabled by rationally designing the MASD process. In addition, by simply tuning in-situ growth kinetics of ZnO nanostructures in the process, the morphology of the Ag-ZnO nanocomposite film is varied, including flower- and nanorod-structure. The enhanced photocatalytic activity of the Ag-ZnO nanocomposite film over the pristine ZnO counterpart is demonstrated by performing the photoelectrochemical (PEC) measurements.
