Pd nanoparticles were successfully introduced into the channels of mesoporous silica MCM-41 with their dispersion well-tuned. We identified the dual role played by CTAB, which was critical for both the micelle template and Pd grafting, leading to the formation of a highly active Pd-MCM-41 nanocomposite for catalysing the Suzuki reaction.
钯纳米颗粒成功引入介孔二氧化硅MCM - 41的孔道中，且其分散性得到了良好调控。我们确定了十六烷基三甲基溴化铵（CTAB）所起的双重作用，它对于胶束模板和钯接枝都至关重要，从而形成了一种用于催化铃木反应的高活性钯 - MCM - 41纳米复合材料。
