Laser Ablation Nanoarchitectonics of Au-Cu Alloys Deposited on TiO Photocatalyst Films for Switchable Hydrogen Evolution from Formic Acid Dehydrogenation.

The regulation of H evolution from formic acid dehydrogenation using recyclable photocatalyst films is an essential approach for on-demand H production. We have successfully generated Au-Cu nanoalloys using a laser ablation method and deposited them on TiO photocatalyst films (Au Cu /TiO). The Au-Cu/TiO films were employed as photocatalysts for H production from formic acid dehydrogenation under light-emitting diode (LED) irradiation (365 nm).
