A facile method was developed for surface modification of supported nano-Pd catalysts with tailorable wettability. The obtained Pd/TiO2@POS catalytic materials could be used in the controllable synthesis of styrene and ethylbenzene obtained from hydrogenation of phenylacetylene and the selective synthesis of imine and N-methylanilines via a reductive amination reaction. The precise modification of the hydrophilicity/hydrophobicity of the catalyst surface is crucial to realize this targeted transformation.
开发了一种简便的方法用于对具有可定制润湿性的负载型纳米钯催化剂进行表面改性。所获得的Pd/TiO2@POS催化材料可用于通过苯乙炔加氢可控合成苯乙烯和乙苯，以及通过还原胺化反应选择性合成亚胺和N-甲基苯胺。精确调节催化剂表面的亲水性/疏水性对于实现这种定向转化至关重要。
