A photofuel cell comprising titanium oxide and silver(<scp>i</scp>/0) photocatalysts for use of acidic water as a fuel

Abstract

A photofuel cell comprising two photocatalysts TiO2 and Ag-TiO2 is demonstrated. The open circuit voltage, short circuit current, and maximum electric power of the PFC were 1.59 V, 74 μA, and 14 μW, respectively. The electron flow was rectified due to the Schottky barrier between TiO2 and Ag nanoparticles.
