在无金属和无氢条件下，考察了糠醛在2-戊醇悬浮液中的光催化加氢反应。观察到高化学选择性，即，只有FAL的羰基被还原成羟甲基，导致几乎定量地转化成糠醇（FOL），表观量子效率为17%。2-戊醇同时转化为2-戊酮满足高的化学计量与FAL到FOL，表明双升级的FAL和醇是可能的，通过光催化过程。
Photocatalytic hydrogenation of furfural (FAL) was examined in 2-pentanol suspensions of TiO2 under metal-free and hydrogen-free conditions. High chemoselectivity was observed, i.e., only the carbonyl group of FAL was reduced to a hydroxymethyl group, resulting in almost quantitative conversion to furfuryl alcohol (FOL) with an apparent quantum efficiency of 17%. 2-Pentanol was simultaneously converted to 2-pentanone satisfying a high stoichiometry with FAL to FOL, indicating that double up-grading of FAL and alcohol was possible via a photocatalytic process.
