Abstract:
Cu2 O/CuOx (x=0, 1) nanocomposites with well-defined morphologies have been widely applied in catalytic reactions. However, people still understand less about tuning interfacial Cu-O atomic structures for enhanced catalytic applications, and a special review on this topic has not been reported so far. Herein, we summarize our understanding on tuning interfacial Cu-O atomic structures based on the literature, including the formation as well as evolution mechanism of Cu-O interfaces in Cu2 O/CuO and Cu2 O/Cu systems, and the improved performances in the fields of CO oxidation, NOx oxidation, photoelectrocatalysis, water gas shift reaction, photodegradation of organic dyes, hydrogen evolution, and photoreduction of CO2 . Finally, we briefly propose several potential research directions.

Electronic Structure of Atoms
An atom comprises protons and neutrons, which are contained inside the dense, central core called the nucleus, with electrons present around the nucleus. Taking into account the wave–particle duality of electrons and the uncertainty in position around the nucleus, quantum mechanics provides a more accurate model for the atomic structure. It describes atomic orbitals as the regions around the nucleus where electrons of discrete energy exist, characterized by four quantum...
