Novel properties of graphene have been well documented, whereas the importance of nanosheets of MoS2 and other chalcogenides is increasingly being recognized over the last two to three years. Borocarbonitrides, BxCyNz, with insulating BN and conducting graphene on either side are new materials whose properties have been attracting attention. These two-dimensional (2D) materials contain certain common features. Thus, graphene, MoS2, and borocarbonitrides have all been used in supercapacitor applications, oxygen reduction reactions (ORRs), and lithium-ion batteries. It is instructive, therefore, to make a comparative study of some of the important properties of these layered materials. In this article, we discuss properties related to energy devices at length. We examine the hydrogen evolution reaction facilitated by graphene, MoS2, and related materials. We also discuss gas and radiation sensors based on graphene and MoS2 as well as gas storage properties of graphene and borocarbonitrides. The article should be useful in making a judicious choice of which 2D material to use for a particular application.
石墨烯的新奇特性已有充分记载，而在过去两到三年间，二硫化钼和其他硫族化物纳米片的重要性也日益得到认可。硼碳氮化物（BxCyNz）两侧分别是绝缘的氮化硼和导电的石墨烯，是一类特性备受关注的新型材料。这些二维（2D）材料具有某些共同特征。因此，石墨烯、二硫化钼和硼碳氮化物都已应用于超级电容器、氧还原反应（ORR）和锂离子电池。所以，对这些层状材料的一些重要特性进行比较研究具有指导意义。在本文中，我们详细讨论与能量装置相关的特性。我们研究了由石墨烯、二硫化钼及相关材料促进的析氢反应。我们还讨论了基于石墨烯和二硫化钼的气体和辐射传感器，以及石墨烯和硼碳氮化物的储气特性。本文对于明智选择用于特定应用的二维材料应具有参考价值。
