Entanglement of Spatial and Energy Segmentation for C1 Pathways in CO2 Reduction on Carbon Skeleton Supported Atomic Catalysts

“…GDY is constructed by the combination of benzene rings and the diacetylenic groups, which consist of the sp-and sp2-hybridized carbon atoms for broad applications in energy conversion and storage. [29][30][31][32] More importantly, GDY possesses the intrinsic porous 2D structure, which supplies sufficient anchoring space to reach the atomically dispersed metals. In addition, the high electronic conductivity and charge carrier mobility of GDY make them become the promising material for both electrocatalysis and photocatalysis.…”

Atomic cation-vacancy engineering of two-dimensional nanosheets for energy-related applications

“…There are possible approaches to achieving this goal including the synthesis of high-quality 2D nanosheets, the designation of certain chemical reactions for the introduction of cation vacancies, and precise control of the preparation conditions of cation vacancies in various 2D materials. [121][122][123] However, it is still difficult to detect the quantity and spatial distribution of cation vacancies in 2D nanosheets with standard characterization techniques. Considering the probable inhomogeneity of the existence of cation vacancies, it is essential to gain an in-depth understanding of the vacancy distribution, especially to acquire its intrinsic effect on the performance for energy storage and conversion.…”
