Surface and interface designs are an efficient strategy to fabricate innovative and advanced catalysts. A prerequisite for this is a fundamental understanding of the structure-performance relations of catalyst nanoparticles, which, however, remains a formidable challenge due to the complexity of heterogeneous catalysis. Recent progresses in catalytic nanocrystals with uniform and well-defined structures, in situ characterization techniques, and theoretical calculations have offered opportunities for the fundamental studies of heterogeneous catalysis, and the achieved outputs are turning the innovation of efficient catalysts via surface and interface designs into a reality. Herein, the recent advances in the fundamental-understanding-directed rational surface and interface designs for heterogeneous catalysis, including crystal phase design, morphology/facet design, and size design, are presented. Perspectives are also discussed for the innovation of efficient catalysts via the fundamental-understanding-directed surface and interface designs followed by controlled synthesis.
表面和界面设计是制造创新和先进催化剂的有效策略。这需要对催化剂纳米粒子的结构-性能关系有一个基本的了解，但由于多相催化的复杂性，这仍然是一个艰巨的挑战。具有均匀和明确结构、原位表征技术和理论计算的催化纳米晶体的最新进展为多相催化的基础研究提供了机会，所取得的成果正在将通过表面和界面设计实现高效催化剂的创新变为现实。本文介绍了在多相催化中，通过对晶体相、形貌/晶面和尺寸设计等进行基础理解导向的理性表面和界面设计的最新进展。同时还讨论了通过基础理解导向的表面和界面设计以及随后的控制合成来创新高效催化剂的前景。
