Influence of Surface Morphology and Conductivity on Photocatalytic Performance of Solution-Processed Zinc Oxide Film.

Solution-processed ZnO films with various structures have been fabricated and the influence of surface morphology and conductivity on photocatalytic performance, including improvement of conductivity, hydrogen production, and photodegradation of rhodamine B, has been investigated. Surface morphology was controlled by solution conditions, and as-fabricated films had rod, dense, and flower-like structures. Improved conductivity was revealed by the photocatalytic activity of ZnO, the influence of surface morphology on the photodegradation of rhodamine B, and the relationship with conductivity and hydrogen production.
