Nano- and micro-structural control of WO photoelectrode films through aqueous synthesis of WO·HO and (NH)WO precursors.

Nano- and micro-structured tungsten trioxide (WO) photoelectrode films were prepared through an aqueous solution route. WO precursor layers were deposited on glass substrates through heterogeneous nucleation from (NH)WO aqueous solutions at 50-60 °C. The crystal phase of the precursors changed from WO·HO to (NH)WO with increasing (NH)WO concentration (), which involved a morphological change from micron-scale plates to nano-scale fine particles.
