Modern society has an ever-increasing demand for environmentally friendly catalytic processes. Catalysis research is working towards a solution through the development of efective heterogeneous catalysts for environment-related applications. Nanotechnologies have provided efective strategies for the preparation of nanocrystals(NCs) with well-deined sizes, shapes and compositions. Precise control of these NCs provides an important foundation for the studies of structure-performance relationships in catalysis, which is critical to the design of NCs with optimized catalytic performances for practical applications. We focus on recent advances in the development of botom-up strategies to control NCs structures for some key catalytic applications, including CO oxidation, selective oxidation of alcohols, semihydrogenation of alkynes, and selective hydrogenation of unsaturated aldehydes and nitrobenzene. hese key applications have been a popular research focus because of their signiicance in green chemistry. Herein we also discuss the scientiic understandings of the active species and active structures of these systems to gain an insight for rational design of eicient catalytic systems for these catalytic reactions.
