title: Remote energy storage in Ni(OH)2 with TiO2 photocatalyst.
abstract: Oxidative energy generated by UV-irradiated TiO2 photocatalyst was stored in Ni(OH)2 that was 12.5-50 microm apart from the TiO2. It is likely that active oxygen species generated on TiO2 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 H2O2.
