Abstract

MoO₃ was characterized and compared with WO₃ as an energy storage material for TiO₂ photocatalysts. MoO₃ exhibits larger charging and discharging capacities than does WO₃ when electrochemically charged at -0.4V versus Ag/AgCl (photopotential of TiO₂). Self-discharging is also faster, reflecting greater ability for oxygen reduction. MoO₃ combined with TiO₂ is chargeable under UV light in a NaCl solution and in moisturized air.
