| Research Abstract |
Various aromatic ketones such as acetophenone derivatives were photocatalytically hydrogenated on titanium dioxide under UV light irradiation. The desired secondary alcohols were obtained with excellent chemical efficiency(almost 100% yields) by choosing ethanol as a sacrificial hole scavenger, which was oxidized into acetaldehyde. On the other hand, tantalate photocatalysts(NaTaO_3 and Ta_2O_5) exhibited simultaneous redox coupling reactions including reductive formation of formic acid from carbon dioxide and oxidative production of acetic acid from ethanol.
