WO3 Nanowires: Iluminado ao sol do Novo Mundo! The cover picture illustrates a tungsten oxide photoanode and a counter electrode that generate oxygen and hydrogen gas by water splitting under solar irradiation. The semiconductor properties of tungsten oxide are excellently suited to the design of a photoelectrochemical cell. On page 2341 of this issue, the Full Paper by Edson Leite and co-workers from the Federal University of Sao Carlos (Brazil) outlines a strategy for the production of photoanodes with excellent photoelectrochemical performance based on deposition of tungsten oxide nanowires. In situ TEM experiments are used to understand morphological transformation phenomena that occur during the sintering process.
