Abstract

Copper nanoparticles (NPs) supported on a series of undoped and doped graphene materials (Gs) have been obtained by pyrolysis of alginate or chitosan biopolymers, modified or not with boric acid, containing Cu(2+) ions at 900 °C under inert atmosphere. The resulting Cu-G materials containing about 17 wt % Cu NPs (from 10 to 200 nm) exhibit high catalytic activity for the dehydrogenative coupling of silanes with alcohols. The optimal material consisting on Cu-(B)G is more efficient than Cu NPs on other carbon supports.

摘要

通过在惰性气氛下于 900°C 热解含 Cu(2+)离子的未经修饰或经硼酸修饰的藻酸盐或壳聚糖生物聚合物，得到了负载在一系列未掺杂和掺杂石墨烯材料（Gs）上的铜纳米颗粒（NPs）。所得的含约 17wt%CuNPs（10 至 200nm）的 Cu-G 材料对硅烷与醇的脱氢偶联具有高催化活性。由 Cu-(B)G 组成的最佳材料比其他碳载体上的 CuNPs 更有效。
