Various ratios of palladium nanoparticles supported on mesoporous natural phosphate (Pd@NP) were prepared using the wetness impregnation method. The prepared catalysts were characterized by IR, XRD, CV, SEM, EDX, XRF, TEM and BET analysis. The reduction and preparation of the palladium nanoparticles afford a crystallite size of 10.88 nm. The performance of the synthesized catalyst was investigated in
使用湿法浸渍法制备了不同比例负载在介孔天然磷酸盐(Pd @ NP)上的钯纳米粒子。通过IR,XRD,CV,SEM,EDX,XRF,TEM和BET分析对所制备的催化剂进行表征。钯纳米颗粒的还原和制备提供了10.88nm的微晶尺寸。在以雪松油为模型底物的α-,β-和γ-喜马al林混合物的无溶剂脱氢芳构化过程中,研究了合成催化剂的性能。为了实现有效和选择性的催化,研究了各种萜烯如柠檬烯,柠檬烯酮,香芹酮,香芹酚和紫苏醇的催化脱氢芳构化。Pd @ NP催化剂在萜烯脱氢芳构化反应中具有很高的催化活性,选择性和可回收性。
