“…Therefore, N doping increases the selectivity of C 5+ hydrocarbons. A similar conclusion can be proven in the work of Lama et al [99]. They modified CNTs with N atoms, and found that N doping stabilized smaller Fe particles (nanoscale) and could even stabilize atomic-level Fe species.…”

The excessive consumption of fossil fuels has resulted in massive carbon emissions and serious ecological and environmental crises. Therefore, achieving the efficient utilization of waste carbon sources is considered as an important pathway to addressing the aforementioned issues in the context of carbon neutrality. Developing and designing suitable catalyst materials has become the key to converting COx into valuable platform chemicals and value-added liquid fuels (e.g., CO, CH4, CH3OH, and C2+ hydrocarbons). A moderate interaction between nitrogen-doped carbon materials and active metals is more favorable for the progress of the COx hydrogenation reaction compared to traditional metal oxide carriers. In this work, we comprehensively summarize the synthesis methods of N-doped carbon materials and the relevant research progress in the field of COx hydrogenation. In addition, a general assessment of carbon-based catalysts for COx hydrogenation reactions, concerning the support and metal properties, the activity and product selectivity, and their interactions is systematically discussed. Finally, this review discusses the roles of N-doped carbon materials, the current challenges, and future development directions.

“…[ 20,41–43 ] For example, the postsynthetic functionalization of CNTs with nitrogen‐containing surface groups by controlled oxidation and ammonia treatment can be assumed to lead to homogenous functionalization. [ 44 ] Hummers’ method is meanwhile a widely established tool for the homogeneous oxidation of graphite. [ 45 ] In the case of nanoporous carbon materials, homogenous functionalization is more difficult and indeed, post‐synthetic modification of such materials often results in a broad distribution of bonding motives of heteroatoms.…”

Nanoporous carbon materials can cover a remarkably wide range of physicochemical properties. They are widely applied in electrochemical energy storage and electrocatalysis. As a matter of fact, all these applications combine a chemical process at the electrode–electrolyte interface with the transport (and possibly the transfer) of electrons. This leads to multiple requirements which can hardly be fulfilled by one and the same material. This “functionality‐conductivity‐dilemma” can be minimized when multiple carbon‐based compounds are combined into porous all‐carbon hybrid nanomaterials. This article is giving a broad and general perspective on this approach from the viewpoint of materials chemists. The problem and existing solutions are first summarized. This is followed by an overview of the most important design principles for such porous materials, a chapter discussing recent examples from different fields where the formation of comparable structures has already been successfully applied, and an outlook over the future development of this field that is foreseen.
