Special Issue Information

Dear Colleagues,

Nowadays, carbon dioxide is one of the most significant greenhouse gases. The worldwide accepted sustainable development goals strongly express the need to reduce greenhouse gas emissions. Nevertheless, the current shape of the chemical industry indicates the commitment to processes that lead to emissions of carbon oxides. The most environmentally friendly way of waste management is reuse as a raw material. Among the methods of CO2 reuse, dry reforming (DR) seems to be a very promising technique due to the possibility of synthesising gas with the required products’ molar ratio in the output stream.

Dry reforming takes place in the presence of catalysts. Commercially used catalysts are based on nickel particles due to their high activity and its relatively low price. However, DR reaction conditions favour sintering of the active particles and coking of the catalyst. The size, shape and composition of catalytic materials are crucial factors determining the activity and stability. Therefore, developing new catalysts with a high activity and catalytic stability is undoubtedly still a scientific challenge and of special interest.

The Special Issue will gather research articles and short reviews related to the dry reforming of carbon and hydrogen-containing molecules (e.g., hydrocarbons, diols, alcohols, plastics), including developing new catalysts for DR of desired morphology, investigation of process parameters, investigation of catalysts’ synthesis routes and studies on the stability of materials in under DR conditions. Computational studies on catalysts within the above scope are also welcome.

Perovskite oxides were widely used as precursors for developing metal-support type catalysts. It is attractive to explore the catalytic properties of the oxides themselves for dry reforming of methane (DRM). We synthesized LaNixCr1−xO3 (x = 0.05–0.5) samples in powder form using the sol-gel self-combustion method. Ni atoms are successfully doped into the LaCrO3 perovskite lattice. The perovskite grains are polycrystalline, and the crystallite size decreases with increasing Ni content. We demonstrated that the LaNixCr1−xO3 perovskites show intrinsically catalytic activity for DRM reactions. Reducing the Ni content is helpful to reduce carbon deposition resulting from the metal Ni nanoparticles that usually coexist with the highly active perovskite oxides. The CH4 conversion over the LaNi0.1Cr0.9O3 sample reaches approximately 84% at 750 °C, and the carbon deposition is negligible. Full article

Emissions of greenhouse gases and growing amounts of waste plastic are serious environmental threats that need urgent attention. The current methods dedicated to waste plastic recycling are still insufficient and it is necessary to search for new technologies for waste plastic management. The pyrolysis-catalytic dry reforming (PCDR) of waste plastic is a promising pro-environmental way employed for the reduction of both CO2 and waste plastic remains. PCDR allows for resource recovery, converting carbon dioxide and waste plastics into synthetic gas. The development and optimization of this technology for the high yield of high-quality synthesis gas generation requires the full understanding of the complex influence of the process parameters on efficiency and selectivity. In this regard, this review summarizes the recent findings in the field. The effect of process parameters as well as the type of catalyst and feedstock are reviewed and discussed. Full article

Coking and metal sintering are limitations of large-scale applications of Ni/Al2O3 catalysts in DRM reactions. In this review, several modification strategies to enhance the anti-deactivation property of Ni/Al2O3 are proposed and discussed with the recently developed catalyst systems, including structure and morphology control, surface acidity/basicity, interfacial engineering and oxygen defects. In addition, the structure–performance relationship and deactivation/anti-deactivation mechanisms are illustrated in depth, followed by prospects for future work. Full article
