摘要
Recent developments in nanochemistry offer precise morphology control of nanomaterials, which has significant impacts in the field of heterogeneous catalysis. Rational design of bifunctional catalysts can influence various aspects of catalytic properties. In this review, a new class of bifunctional catalysts with a metal@silica yolk-shell nanostructure is introduced. This structure has many advantages as a heterogeneous catalyst since it ensures a homogeneous environment around each metal core, and particle sintering is effectively eliminated during high temperature reactions. The catalysts exhibit high activity and recyclability in gas- and solution-phase reactions. It is anticipated that appropriate selection of bifunctional components and optimal structural control will significantly further enhance the catalytic properties, and enable target reaction-oriented development of new catalysts.
在 nanochemistry 的最近的开发提供 nanomaterials 的精确形态学控制，它在异构的催化作用的领域里有重要影响。bifunctional 催化剂的合理设计能影响催化性质的各种各样的方面。在这评论，有 metal@silica 蛋黄壳 nanostructure 的 bifunctional 催化剂的一个新班被介绍。自从它保证在每个金属核心附近的同类的环境，和粒子 sintering 有效地在高温度反应期间被消除，这结构作为异构的催化剂有许多优点。催化剂展出高活动和再循环能力在煤气阶段并且答案阶段反应。bifunctional 部件和最佳的结构的控制的适当选择将进一步显著地提高催化性质，这被期望，并且启用目标新催化剂的面向反应的开发。
