Modification of titanium dioxide (TiO2) photocatalysts with chiral reagents was evaluated by the hydrogenation of aromatic ketones. The strong adsorption of chiral mandelic acid (R)-MA on TiO2 was confirmed by comparing the inhibition effect IR values. The enantioselectivities were affected by not only the chiral reagents but also the TiO2 crystalline samples, suggesting that the interaction between aromatic ketones and MA on TiO2 should depend on the surface structure and morphology of TiO2 particles.
用手性试剂修饰二氧化钛（TiO2）光催化剂，并通过芳香酮的加氢反应进行评价。通过比较抑制效应 IR 值，证实了手性扁桃酸（R）-MA 对 TiO2 的强烈吸附。对映选择性不仅受手性试剂影响，还受 TiO2 结晶样品影响，表明芳香酮与 TiO2 上 MA 之间的相互作用应取决于 TiO2 颗粒的表面结构和形态。
