摘要
Developing innovative catalysts continues to be a pivotal interest within the heterogeneous catalysis area.The carbonaceous material ND@G,featuring a sp^(2)/sp^(3)hybrid architecture,comprises a nanodiamond(ND)core structure encased within an ultrathin graphitic nanoshell(G),and has been widely exploited as a metal-free catalyst or a support for metal catalyst.Its unique curved zero-dimensional structure/surface and tunable defective surface characteristics endow it with outstanding performance in different heterogeneous catalytic systems.The present review summarized the construction of the diverse types of ND@G and a wide-ranging valorization of structure-activity relation with its catalytic mechanism in various reactions.The recent advancements in the impact of active sites’architecture and the interaction between metal and support(preventing the as-formed metal species migration and agglomeration based on ND@G)on the catalytic performance of supported metal catalysts are particularly highlighted.The current challenges and outlooks/opportunities confronted by ND@G materials in catalysis are prospected by virtue of its fundamental physicochemical characterizations and potential catalytic estimation.This in-depth analysis seeks to pave the way for effective utilizing the ND@G in catalytic processes.Based on our knowledge,we also identify the challenges along with this area and offer some perspectives on how to overcome them.
