杂原子掺杂的多孔碳膜（HPCO 2）具有定制的孔结构、化学组成、原子结构顺序和表面状态，代表了令人兴奋的多孔碳材料家族，其在催化、水处理、生物过滤、能量转换/储存等方面具有多种潜在应用。传统的多孔碳膜具有内在的结构完整性、互连性和跨越原子到宏观世界的化学纯度，并且已被普遍地结合到装置中作为分离器或化学惰性导电载体，从而避免了它们的细粉末对应物的不可避免的复杂加工和结构弱点。受碳材料独特的杂原子掺杂效应的影响，近年来HPCMM的研究迅速发展，不仅关注于导电载体或隔膜，还关注于能源器件中的电（共）催化剂。多孔性、杂原子的结合和膜状态的协同作用创造了生动的轮廓图案和新的任务特定用途。还值得注意的是，HPC碳纳米管的固有结构优点加上高电子电导率使它们作为可靠的无粘合剂模型电极来获得多孔碳在电化学环境中的固有结构-性能关系，排除了与基于碳粉的电极中的聚合物粘合剂相关的复杂和不利因素。高性能碳纳米管具有良好的结构可控性和多孔性，在原子尺度和宏观尺度上都具有很高的理论价值和实用价值。本文的唯一目的是将这组多孔碳材料带到最前沿，以便更好地了解它们的综合性能和功能，为碳社区服务，以解决我们社会中紧迫的材料挑战。本文重点介绍了高分子聚合物膜的最新发现和研究进展，特别是在如何通过合理的结构设计，特别是以富含杂原子的聚离子液体（PILs）为牺牲模板构建的多孔聚合物膜，来调控高分子聚合物膜的结构和性能方面的研究进展。我们也将强调碳化工艺和最先进的电化学应用HPCO 2。讨论了异质结掺杂和多孔体系中的关键因素和思路。在这些成就的基础上，展望了未来的挑战和充满希望的潜力。
Heteroatom-doped porous carbon membranes (HPCMMs) with a tailor-made pore architecture, chemical composition, atomic structural order, and surface state represent an exciting family of porous carbon materials for diverse potential applications in catalysis, water treatment, biofiltration, energy conversion/storage, and so forth. Conventional porous carbon membranes possess intrinsic structural integrity, interconnectivity, and chemical purity across the atomic-to-macro world and have been popularly incorporated into devices as separators or chemically inert conductive supports, circumventing otherwise the inevitable complicated processing and structure weakness of their fine powderous counterpart. Motivated by the distinguished heteroatom-doping effect that revolutionizes the chemical and physical nature of carbon materials, the HPCMM research surges very recently, and focuses not only on the eminent conductive supports or separators but also on electro(co)catalysts in energy devices. Synergy of the porous nature, incorporation of heteroatoms, and the membrane state creates a vivid profile pattern and new task-specific usage. It is also noteworthy that the inherent structural merits of HPCMMs plus a high electron conductivity imbue them as a reliable binder-free model electrode to derive the intrinsic structure–property relationship of porous carbons in electrochemical environments, excluding the complex and adverse factors in association with polymer binders in carbon powder-based electrodes. HPCMMs are of both intense academic interest and practical value because of their well-defined properties endowed by controllable structure and porosity at both atomic and macroscopic scales in a membrane form. The sole aim of this article is to bring this group of porous carbon materials to the forefront so their comprehensive properties and functions can be better understood to serve the carbon community to address pressing materials challenges in our society. In this Account, we highlight the latest discovery and proceedings of HPCMMs, particularly the advancements in how to tailor structures and properties of HPCMMs by rational structure design of porous polymer membranes as sacrificial template built up especially from heteroatom-rich poly(ionic liquid)s (PILs). We will also stress the carbonization craft and the state-of-the-art electrochemical applications for HPCMMs. Key factors and thoughts in heteroatom doping and porous systems in HPCMMs are discussed. A future perspective of the challenges and promising potential of HPCMMs is cast on the basis of these achievements.
