Herein, we report the synthesis of nickel nanoparticles under mild conditions using porous alginate-g-poly(p-styrene sulfonamide-co-acrylamide) as a protecting/stabilizing agent and sodium borohydride as a reducing agent. The porous cross-linked polymeric support was prepared via combining the use of sol-gel, nanocasting, and crosslinking techniques, in which the p-styrene sulfonamide monomer (PSSA)
在此,我们报道了使用多孔藻酸盐-g-聚(对苯乙烯磺酰胺-共-丙烯酰胺)作为保护/稳定剂和硼氢化钠作为还原剂在温和条件下合成镍纳米粒子。通过结合使用溶胶-凝胶、纳米铸造和交联技术制备了多孔交联聚合物载体,其中对苯乙烯磺酰胺单体(PSSA)和N,N'-亚甲基双(丙烯酰胺)(MBA)在 SiO2 纳米粒子 (NP) 模板 (Alg-PSSA-co-ACA) 存在下,交联剂在海藻酸钠表面进行共聚。所制备的催化剂(Alg-PSSA-co-ACA@Ni)对酰肼和芳基碘化物通过异氰化物插入/环化反应一步合成1,3,4-恶二唑表现出较高的催化活性。
