英文摘要: Ultra-high onset potential hinders the application of hematite for photoelectrochemical (PEC) water splitting. Herein, a hematite photo-anode with an unprecedentedly low onset potential of 0.50 V vs. the reversible hydrogen electrode for PEC water oxidation is reported. The drastically reduced onset potential is mainly ascribed to the passivation of the hematite surface states and the gradient structure made by H-2-O-2 flame at high temperature.
