Recently, owing to the discovery of graphene, porous carbons experienced a revitalization in their explorations. However, nowadays, the focus is more on search for suitable energy advancing catalysts sensing, energy storage or thermal/light absorbing features than on separations. In many of these processes, adsorption, although not emphasized sufficiently, can be a significant step. It can just provide a surface accumulation of molecules used in other application-driving chemical or physical phenomena or can be even an additional mechanism adding to the efficiency of the overall performance. However, that aspect of confined molecules in pores and their involvement in the overall performance is often underrated. In many applications, nanopores might advance the target processes or might very directly affect or change the outcomes. Therefore, the objective of this communication is to bring awareness to the role of nanopores in carbon materials, and also in other solids, to scientists working on cutting-edge application of nonporous carbons, not necessary involving the adsorption process directly. It is not our intention to provide a clear explanation of the small pore effects, but we rather tend to indicate that such effects exist and that their full explanation is complex, as complex is the surface of nanoporous carbons.
最近，由于石墨烯的发现，多孔碳在其探索方面经历了复兴。然而，如今，重点更多地放在寻找合适的能源推进催化剂的传感、能量存储或热/光吸收特性上，而不是分离。在许多这些过程中，吸附虽然没有得到足够的重视，但可能是一个重要步骤。它不仅可以提供用于其他驱动应用的化学或物理现象的分子的表面积累，甚至还可以作为一种增加整体性能效率的额外机制。然而，孔中受限分子的这一方面及其对整体性能的影响往往被低估。在许多应用中，纳米孔可能会推进目标过程，或者可能非常直接地影响或改变结果。因此，本通讯的目的是让从事无孔碳前沿应用的科学家们认识到纳米孔在碳材料以及其他固体中的作用，不一定直接涉及吸附过程。我们并非旨在对小孔效应给出清晰的解释，而是倾向于指出这种效应的存在，并且其完整解释很复杂，就像纳米多孔碳的表面一样复杂。
