Abstract

Oxidative energy generated by UV-irradiated TiO₂ photocatalyst was stored in Ni(OH)₂ that was 12.5-50 μm apart from the TiO ₂. It is likely that active oxygen species generated on TiO ₂ diffused into the gas phase and oxidized Ni(OH)₂. Loading the TiO₂ with Pt accelerated the remote energy storage by an order of magnitude. It was revealed that the stored energy could be taken out and used chemically or electrochemically. The oxidized Ni(OH)₂ was reduced by gaseous formaldehyde, formate, ethanol and H₂O ₂.
