Palladium nanoparticles were efficiently prepared in situ by sodium cyanoborohydride reduction of Pd(ii) at room temperature using calcium-cholate hydrogel fibers as templates. The PdNPs self-organize on the gel fibers, which supports the controlled growth as well as stabilization of PdNPs. The hybrid xerogel was used as an efficient catalyst for the Suzuki coupling reaction in water.
钯纳米颗粒通过在室温下使用钙胆酸盐水凝胶纤维作为模板,通过氰硼氢钠还原Pd(II)而有效地制备。钯纳米颗粒自组织在凝胶纤维上,支持钯纳米颗粒的控制生长和稳定化。这种混合干凝胶被用作在水中苏齐基偶联反应的高效催化剂。
