Special Issue Information

Dear Colleagues,

Meso-/nanoporous materials (including zeolites, MOF, COF, ZIF, polymers, etc.) have been widely used as catalysts in the fields of petrochemistry, the coal chemistry industry and fine chemical engineering. The exceptional catalytic performances of these meso-/nanoporous materials are closely related to their well-defined pore structure, tunable acid–base property and high thermal and chemical stability, which can be controllably regulated by altering the crystallization conditions and synthesis parameters. In addition, the large surface area and regular pore structure of meso-/nanoporous materials are conducive to promoting the high dispersion of metal sites and improving the resistance of metal sites to sintering and agglomeration through strong metal–support interactions. All these advantages mean that meso-/nanoporous materials play an increasingly important role in not only the traditional petrochemical and coal chemistry industry, but also in biomass conversion, fuel cell and renewable energy storage.

This Special Issue aims to present the recent progress in the synthesis, characterization and catalytic applications of meso-/nanoporous materials. Original research articles (full papers and communications) and reviews are welcome.

Research areas may include (but are not limited to) the following:

  1. Preparation and characterization of new types of meso-/nanoporous materials;
  2. Applications of meso-/nanoporous materials in the petrochemistry or coal chemistry industry;
  3. Applications of meso-/nanoporous materials in renewable energy storage and conversion;
  4. Applications of meso-/nanoporous materials for adsorption and separation.

The selective hydrogenation of CO2 into high-value chemicals is an effective approach to address environmental issues. Cobalt-based catalysts have significant potential in CO2 hydrogenation reaction systems; however, there is a need to control their selectivity better. In this study, copper is introduced onto Co3O4 nanosheets using the ion exchange reverse loading method. The unique interaction of these materials significantly alters the selectivity of the cobalt-based catalyst. Results from scanning transmission electron microscopy and scanning electron microscopy indicate that this catalyst enables a more even dispersion of copper species in the Co3O4 nanosheets. Temperature-programmed reduction and X-ray photoelectron spectroscopy reveal that the catalyst facilitates the metal–metal interaction between Co and Cu. Temperature-programmed desorption experiments for CO2 and H2 demonstrate that the close interaction between Co and Cu modifies CO2 adsorption, leading to differences in catalytic activity. Moreover, the catalyst effectively suppresses CO2 methanation and promotes methanol formation by altering the alkalinity of the catalyst surface and weakening the hydrogen dissociation ability.

Among various iron carbide phases, χ-Fe5C2, a highly active phase in Fischer–Tropsch synthesis, was directly synthesized using a wet-chemical route, which makes a pre-activation step unnecessary. In addition, χ-Fe5C2 nanoparticles were encapsulated with mesoporous silica for protection from deactivation. Further structural analysis showed that the protective silica shell had a partially ordered mesoporous structure with a short range. According to the XRD result, the sintering of χ-Fe5C2 crystals did not seem to be significant, which was believed to be the beneficial effect of the protective shell providing restrictive geometrical space for nanoparticles. More interestingly, the protective silica shell was also found to be effective in maintaining the phase of χ-Fe5C2 against re-oxidation and transformation to other iron carbide phases. Fischer–Tropsch activity of χ-Fe5C2 in this study was comparable to or higher than those from previous reports. In addition, CO2 selectivity was found to be very low after stabilization. Full article

Cu(im)2-derived Cu@N-C composites were used for the first time as efficient heterogeneous catalysts for one-pot 1,3-dipolar cycloaddition of terminal alkynes, aryl halides, and sodium azide to preparation of 1,4-disubstituted 1,2,3-triazoles with broad substrate scope and high yields. The catalyst can be easily reused without the changes of structure and morphology, and the heterogeneity nature was confirmed from the catalyst recyclability and metal leaching test. Full article
