Microwave-assisted fabrication of porous hematite photoanodes for efficient solar water splitting

Porous hematite photoanodes with wormlike networks were prepared by microwave-assisted rapid annealing of β-FeOOH grown directly on a FTO glass. The enhanced electrochemical characteristics such as large surface area and good permeation of an electrolyte lead to the excellent photoelectrochemical performance toward the solar-driven water splitting for hydrogen production.
