[交流] ACS Catalysis上利用原子层沉积ALD设计催化剂的一篇综述已有1人参与

Abstract
Atomic layer deposition (ALD) has emerged as an interesting tool for the
atomically precise design and synthesis of catalytic materials. Herein, we discuss examples
in which the atomic precision has been used to elucidate reaction mechanisms and catalyst
structure−property relationships by creating materials with a controlled distribution of
size, composition, and active site. We highlight ways ALD has been utilized to design
catalysts with improved activity, selectivity, and stability under a variety of conditions (e.g.,
high temperature, gas and liquid phase, and corrosive environments). In addition, due to
the flexibility and control of structure and composition, ALD can create myriad catalytic
structures (e.g., high surface area oxides, metal nanoparticles, bimetallic nanoparticles,
bifunctional catalysts, controlled microenvironments, etc.) that consequently possess
applicability for a wide range of chemical reactions (e.g., CO2 conversion, electrocatalysis,
photocatalytic and thermal water splitting, methane conversion, ethane and propane dehydrogenation, and biomass conversion).
Finally, the outlook for ALD-derived catalytic materials is discussed, with emphasis on the pending challenges as well as areas of
significant potential for building scientific insight and achieving practical impacts.
