This perspective is aimed at presenting some issues that, in our opinion, have still to be better addressed in the field of graphenes as catalysts. After an introductory section, the article comments on how the number of layers present on the catalyst, termed frequently as graphene, could be in some cases in contradiction with good practices about what should be or not considered as graphene. It will also be commented that some of the characterization tools that are employed in some cases for graphenes as catalysts, like specific surface area measurements based on isothermal gas adsorption on powders or XRD patterns are not well suited to characterizing graphenes. The potential role of impurities and structural defects in graphene catalysis has been highlighted showing the importance of providing exhaustive analysis of the materials. This perspective includes a final section with our view on future progress and wider consensus in the use of graphene in catalysis.

在催化中使用石墨烯的一般方面

这种观点旨在提出一些我们认为在石墨烯作为催化剂领域仍需更好解决的问题。在引言部分之后，该文章评论了在某些情况下，催化剂上存在的层数（经常被称为石墨烯）可能与关于应将石墨烯视为或不应当视为石墨烯的良好实践相矛盾。还将评述，在某些情况下用于石墨烯作为催化剂的某些表征工具，例如基于粉末或XRD图上等温气体吸附的比表面积测量，不太适合表征石墨烯。已经强调了杂质和结构缺陷在石墨烯催化中的潜在作用，表明提供详尽的材料分析的重要性。
