最近在纳米科学中以原子精度控制纳米粒子的努力在溶液相化学中取得了成功，开辟了新的机会。这些产品，原子级精确的纳米簇（NC），不仅在组成上定义明确，而且在结构上也非常精确，在核心和表面上进行了前所未有的定制，以实现特定的功能。在这个角度来看，我们首先强调最近的工作在金属氢化物NC催化氢化的应用，然后反映原子精确的金属NC的催化机会。金属纳米粒子作为一类新的材料，对于实现在原子/分子水平上理解催化机制的目标（例如，活性中心的构建）和开发设计对重要反应具有高活性和选择性的新催化剂的规则。在原子水平上定制NC催化剂将在未来的催化研究中带来许多令人兴奋的机会。
Recent efforts in nanoscience to control nanoparticles with atomic precision have met with success in solution-phase chemistry, opening new opportunities. The products, atomically precise nano clusters (NCs), are not only compositionally well-defined but also structurally precise with unprecedented tailoring over the core and surface for specific functionalities. In this Perspective, we first highlight recent work in metal hydride NCs for applications in catalytic hydrogenation and then reflect on the catalytic opportunities of atomically precise metal NCs. Metal NCs, as a new class of material, hold great promise for realizing the goals of understanding catalytic mechanisms at the atomic/molecular level (e.g., construction of active sites) and developing rules designing new catalysts with high activity and selectivity for important reactions. Tailoring NC catalysts at the atomic level will bring many exciting opportunities in future catalysis research.
