【摘要】 通过一步法将纳米Pd负载于二维氮化碳纳米片（g-C3N4）上,制得一种新型的二维纳米催化剂Pd/g-C₃N₄NSs（1）,其结构和形貌经TEM,XRD和XPS表征。以卤代苯与取代苯硼酸的Suzuki-Miyaura反应为探针反应,研究了1的催化性能。结果表明:1催化活性较好,TOF为53 000 h-1,部分产物收率高于99%,循环使用3次,其催化性能基本不变。更多还原

【Abstract】 A novel 2D nano-catalyst,Pd/g-C₃N₄NSs（1）,was prepared by supporting nano-Pd on gC3N4 NSs via one-step method. The structure and morphology were characterized by TEM,XRD and XPS. The catalytic properties of 1 were investigated by Suzuki- Miyaura reaction of aryl halide with substituted phenylboronic acid. The results showed that 1 exhibited good catalytic property with 53 000h- 1of TOF. Yield of partial products were over 99% and the catalytic performance of 1 remain stable after cycling for three times.更多还原
