Because water is involved in the formation of furfural (FFR), aqueous-phase selective hydrogenation of FFR to furfuryl alcohol (FOL) has the potential for industrial applications, but it has not yet been well exploited. Here, partially reduced TiOx-modified Ni nanocatalysts were studied. The Ni–TiO2 interaction adjusts the Ni electron structure and affects the catalyst adsorption properties. FFR is adsorbed on the TiOx oxygen vacancy (OV) by C═O, and the FOL selectivity is positively correlated with the surface OV content. The active H atoms dissociated on Ni spillover to the TiOx surface and then attack the adsorbed FFR C═O. The precise synergistic effect of Ni and OV improves the comprehensive performance of FFR hydrogenation. Under mild conditions, FFR conversion can reach 92.5% and FOL selectivity can be as high as 96.8%. This is an extremely excellent performance of aqueous-phase FFR selective hydrogenation, and thus, the TiOx-modified Ni nanocatalyst is a very promising candidate for industrial applications.

糠醛在高效 TiOx 修饰的 Ni 纳米催化剂上的工业应用水相选择性加氢
由于水参与糠醛 (FFR) 的形成,因此 FFR 水相选择性加氢制糠醇 (FOL) 具有工业应用的潜力,但尚未得到很好的开发。在此,研究了部分还原的 TiO x修饰的 Ni 纳米催化剂。Ni-TiO 2相互作用调节Ni电子结构并影响催化剂吸附性能。FFR通过C= O吸附在TiO x氧空位(O V)上,并且FOL选择性与表面O V含量正相关。活性 H 原子在 Ni 溢出时离解到 TiO x表面,然后攻击吸附的 FFR C=O。Ni和O V的精确协同效应提高了 FFR 加氢的综合性能。在温和条件下,FFR转化率可达92.5%,FOL选择性可高达96.8%。这是水相FFR选择性加氢的极其优异的性能,因此,TiO x修饰的Ni纳米催化剂是非常有前途的工业应用候选者。
