摘要

手性表面相互作用作为获得手性纯化合物的一种途径，在对映体分离领域具有重要意义。在二氧化硅粘合剂中发现横纹石和一氮石相磷酸铈的膜对手性氨基酸苯丙氨酸具有对映选择性吸附，将外消旋溶液净化为100%的d -对映体。同样地，利用磷酸铈的光催化特性，使外消旋混合物富集到D-L比为9:1。

Inherent Enantioselective Adsorption and Photocatalytic Removal of L-Phenylalanine on Cerium Phosphate Films

Chiral-surface interactions are of immense importance in the field of enantioseparation, as a way of obtaining chirally-pure compounds. Films of both rhabdophane and monazite-phase cerium phosphate in a silica binder were found to exhibit enantioselective adsorption of the chiral amino acid phenylalanine, purifying racemic solutions to 100% of the D-enantiomer. Likewise, using the photocatalytic properties of cerium phosphate led to enriching racemic mixtures to a D-L ratio of 9:1.
