Abstract
Nanoporous graphenes (NPGs) synthesized by CH4-CVD on nanostructured metal oxides templates (M. Yamamoto et al. Chem. Sci. 2022, 13, 3140) are regarded as prominent nanocarbon materials owing to their high electrical conductivity and unprecedentedly high electrochemical stability which originate from their three-dimensionally continuous and seamless nanostructure (M. Yamamoto et al. ACS Appl. Mater. Interfaces 2021, 13, 38613) with a large surface area. Precise template synthesis will realize three-dimensionally ordered NPGs with a spatially controlled seamless graphene structure and fewer edges. These structural features result in super-elastic nature and electrochemical features. To further improve the attractive properties of NPGs in the near future, we review the template synthesis of NPGs and its mechanism, elastic and electrochemical properties, and applications in electrochemical and mechanical devices.
