We demonstrate that films with different morphologies can be synthesized by simply adjusting the pH of this precursor solution using different mineral acids such as HCl and HC1O4, and that this control of film texture represents a way of optimizing photocurrent yield. The best films produced using these methods generated anodic photocurrents of 3.8mA/cm2 for oxidiation of methanol and 2.2mA/cm 2 for water splitting, under AM1.5 simulated solar illumination.
