Special Issue Information

Dear Colleagues,

This issue is a continuation of the previous successful Special Issue “Synthesis and Application of Catalytic Materials in Energy and Environment”.

Catalytic materials have risen to prominence in many high-tech fields. These materials are not categorized according to their nature, bonding form, or processing methods, but rather according to the functions they may perform. The emergence of catalytic materials in the applications of Energy (energy storage, conversion, utilization) and Environment (detection, protection, rehabilitation) has received much more attention from both academic and industry scientists. Thus, it is necessary to provide a platform for the researchers and engineers for discussing the development of catalytic materials in energy and environment.

This Special Issue is devoted to ‘’Synthesis and Application of Catalytic Materials in Energy and Environment’’, including the synthesis, characterization, application, and mechanism analysis of the homogeneous and heterogeneous catalysts in energy and environment. All studies (experimental and theoretical) in the scope of this Special Issue, including original research and review articles, short communications, and perspective articles, are invited for submission.

Sulfur-resistant Mo-based catalysts have become promising for the one-step synthesis of methanethiol (CH3SH) from CO/H2/H2S, but the low reactant conversion and poor product selectivity have constrained its development. Herein, we synthesized K-MoS2/Al2O3 and K-Mo2C/Al2O3 catalysts via the sulfurization and carbonization of K-Mo-based catalysts in the oxidized state, respectively. During the synthesis of CH3SH, both K-Mo2C/Al2O3 and K-MoS2/Al2O3 showed excellent catalytic performance, and the activity of the former is superior to that of the latter. The effect of different treatments on the catalytic performance of Mo-based catalysts was investigated by XRD, BET, Raman spectroscopy, H2-TPR, and reactants-TPD characterization. The results showed that the sulfide-treated sample showed stronger metal-support interactions and contributed to the formation of K2S, which exposed more active sites and stabilized the formation of C-S bonds. Carbonized samples enhanced the activation of H2, which promoted the hydrogenation of the intermediate species of carbonyl sulfide (COS) and thus improved the selectivity of CH3SH. Full article

Co–Mg catalysts for methane combustion were synthesized and studied, revealing the transformation of MgCo2O4 spinel into a CoO–MgO solid solution with oxygen release from the spinel lattice as the calcination temperature increased. Repeated heat treatment of the calcined solid solution at lower temperatures led to spinel regeneration with segregation of the solid solution phase. A TPR of the samples showed the presence of two characteristic peaks, the first of which relates to the transition of Co3+Oh spinel to the Co2+Oh structure of CoO, and the second to the reduction of CoO to Co°. The second peak was observed at 540–620 °C for samples calcined at temperatures below spinel decomposition, and for high-temperature samples at 900–1100 °C. Taking into account the identity of the structure of phases obtained in both cases, the formation of not a true CoO–MgO solid solution, but rather a mixture of ordered oxides (“pseudo-solid solution”) in the low-temperature region, was postulated. A study of the activity of the samples showed the high activity of the spinel systems and a linear relationship between the activation energy of methane oxidation and the heat treatment temperature.

To cope with global warming and increasing carbon emissions, the chemical looping process has attracted attention due to its excellent ability to convert fossil fuel and capture CO2. In this case, chemical looping partial oxidation technology has become the focus of attention due to its advantages in the production of syngas and hydrogen, especially with respect to the design and selection of oxygen carriers, which directly affect the efficiency of the production of syngas and hydrogen. In particular, the conversion of methane can reach 95% in the chemical looping partial oxidation of methane, and the selectivity of syngas, in the range of 700 °C to 900 °C at atmospheric pressure, can reach 99% for twenty or more cycles. In this review, from the perspective of metal oxide selection and structure regarding the chemical looping partial oxidation process, we discuss the role of oxygen carriers in the chemical looping partial oxidation cycle, in which the specific surface area, the lattice oxygen mobility, and the thermal stability are understood as the important factors affecting reactivity. We hope to summarize the design and development of efficient oxygen carriers with high oxygen-carrying capacity and syngas selectivity, as well as contribute to the selection, design, optimization, and redox reaction mechanism of redox catalysts.

Developing cost-effective electroactive materials for advanced energy devices is vital for the sustainable development of electrochemical energy conversion/storage systems. To reduce the fabrication cost of electroactive materials (electrocatalysts and electrodes), growing attention has been paid to low-cost precursors. Recently, mining and metallurgical waste has been used to design electroactive materials, which shows great economic and environmental benefits. Herein, current achievements in the applications of mining and metallurgical waste-derived electroactive materials in sustainable energy conversion/storage fields (batteries, supercapacitors, fuel cells, and small-molecule electro-conversion) are comprehensively analyzed. The waste-to-materials conversion methods and materials’ structure–performance relationships are emphasized. In addition, perspectives related to the further development and applications of waste-derived high-performance electroactive materials are pointed out. Full article
