Special Issue Information

Dear Colleagues,

Mesoporous carbon material (MCM) is a special type of porous solid that has either a disordered or ordered network with a broad or narrow distribution of pores in the range 2–50 nm. MCMs possess unique structural characteristics, including an adjusted surface area, alternative pore size, and tunable pore shape and pore volume, which make them promising candidates for a wide range of catalysis reactions. Specifically, their high surface areas and large pore volumes not only provide a fair number of accessible reaction sites but also facilitate the transport of reactants for surface-related processes, which are particularly advantageous in heterogeneous catalysis. In addition, thanks to the recent developments of synthetic methods and better understanding of MCMs, new subfields such as research on heteroatom-doped mesoporous carbon material and mesoporous carbon-based metal composite materials, which have been discovered in the pursuit of optimized performances in specific applications and a variety of MCMs with wide range of compositions, have rapidly developed. Researchers focus mainly on the exploration of the synthesis and functionalization of MCMs using various methods, such as soft-templating, hard-templating or template-free approaches. The mechanism of synthesis and critical factors of preparation have been well studied, including different precursors and templates, synthesis conditions, and also the way they impact the morphology and composition of the as-obtained MCM. Sufficient attention has been paid to their use in catalytic reactions and their features for determining catalytic performance.

This Special Issue is presented to collate cutting-edge research on designing mesoporous carbon material catalysts, including the preparation and control of MCMs, loading and doping, as well as applications in thermal-, electro-, and photocatalysis. All articles concerning developing new synthetic strategies and the advanced characterization of MCM, application in heterogeneous catalysis, the study of the catalytic mechanism, theoretical studies and the modeling of MCM are welcome.

The poor stability of carbon materials doped with nitrogen limited their development in acetylene hydrochlorination. Therefore, investigating the deactivation reasons of carbon catalysts and researching regeneration methods became the research focus. Herein, carbon-nitrogen materials were synthesized by one-step pyrolysis, which using biomass materials with high nitrogen content, the synthesized material was used in an acetylene hydrochlorination reaction. The acetylene conversion rate of D-GH-800 catalyst was up to 99%, but the catalytic activity decreased by 30% after 60 h reaction. Thermogravimetric analysis results showed that the coke content was 5.87%, resulting in catalyst deactivation. Temperature-programmed desorption verified that the deactivation was due to the strong adsorption and difficult desorption of acetylene by the D-GH-800 catalyst, resulting in the accumulation of acetylene on the catalyst surface to form carbon polymers and leading to the pore blockage phenomenon. Furthermore, based on the catalyst deactivation by carbon accumulation, we proposed a new idea of regeneration by ZnCl2 activation to eliminate carbon deposition in the pores of the deactivated catalyst. As a result, the activity of D-GH-800 was recovered, and lifetime was also extended. Our strategy illustrated the mechanism of carbon deposition, and the recoverability of the catalyst has promising applications. Full article
