“…Catalyst performance is directly affected by the synthesis method, and the dispersion of metal particles on the support, particle size, and type of MSI considerably depend on the synthesis method. Synthesis methods that can produce an active and a stable Ni‐based catalyst for the CMD reaction include impregnation, 19,21‐23,60,77‐80,84,96,100,101,103,104,109‐111,114,127‐130 precipitation, 76,87,95,105,112,131‐134 and the sol‐gel method 67,68,94,97,108,116 . In addition, polyol reduction, 113,118,135 EISA, 85,115 fusion, 82 and emulsion 136 are employed.…”

Summary Hydrogen is a clean energy medium that can potentially replace fossil fuels in home, industrial, and transportation environments. Nonoxidative catalytic methane decomposition (CMD) is an environmentally friendly process that produces hydrogen and solid carbon as products. Among transition metal catalysts, Ni possesses a high degree of activity for methane decomposition. This article reviews the recent advancement (ie, 2015‐2020) of a Ni‐based catalyst for CMD and summarizes its performance. It addresses the effect of promoter, metal composition, support materials selection, catalyst synthesis, operating parameters, and reaction mechanism. Besides, other critical aspects for industrial application of CMD such as reactor design and catalyst regeneration are highlighted. Novelty Statement Catalytic methane decomposition is a promising technology for the co‐production of COx‐free hydrogen and carbon nanomaterials. The Ni‐based catalyst possesses a high degree of activity for catalytic methane decomposition. Regeneration by gasification should be considered to extend the operational life of the Ni‐based catalyst. A fluidized bed reactor is a suitable reactor type for the practical application of catalytic methane decomposition.

“…Lignocellulosic biomass can be crudely categorized as woody, nonwoody, and wastes. ese can be converted into bio-oils, gases, and chemicals through different thermochemical processes such as pyrolysis, gasification, liquefaction, and high-pressure supercritical extraction [26,27]. Lignocellulosic biomass is considered as the largest sustainable energy source and approximately 220 billion tons of dry biomass is produced annually.…”

Lignocellulosic biomass is a vital resource for providing clean future energy with a sustainable environment. Besides lignocellulosic residues, nonlignocellulosic residues such as sewage sludge from industrial and municipal wastes are gained much attention due to its large quantities and ability to produce cheap and clean energy to potentially replace fossil fuels. These cheap and abundantly resources can reduce global warming owing to their less polluting nature. The low-quality biomass and high ash content of sewage sludge-based thermal conversion processes face several disadvantages towards its commercialization. Therefore, it is necessary to utilize these residues in combination with coal for improvement in energy conversion processes. As per author information, no concrete study is available to discuss the synergy and decomposition mechanism of residues blending. The objective of this study is to present the state-of-the-art review based on the thermal coconversion of biomass/sewage sludge, coal/biomass, and coal/sewage sludge blends through thermogravimetric analysis (TGA) to explore the synergistic effects of the composition, thermal conversion, and blending for bioenergy production. This paper will also contribute to detailing the operating conditions (heating rate, temperature, and residence time) of copyrolysis and cocombustion processes, properties, and chemical composition that may affect these processes and will provide a basis to improve the yield of biofuels from biomass/sewage sludge, coal/sewage sludge, and coal/biomass blends in thermal coconversion through thermogravimetric technique. Furthermore, the influencing factors and the possible decomposition mechanism are elaborated and discussed in detail. This study will provide recent development and future prospects for cothermal conversion of biomass, sewage, coal, and their blends.

Among them, Ex‐LSTN showed the highest activity for hydrogen evolution reaction, because of the presence of optimal free energy of H 2 adsorption, but shows inferior activity for OER in which cobalt performs better 133 . The catalyst showed stability issues due to the formation of hydrogenated species of Ni.…”

Role of perovskites as a bi‐functional catalyst for electrochemical water splitting: A review

et al. 2020

View full text Add to dashboard Cite

The electrochemical water splitting by using renewable electricity is being considered as a sustainable, clean and considerable source of hydrogen fuel for future transportation and energy applications. The sluggish kinetics at anode and cathode, thus, require plenty of research work on the development of an efficient and stable electrocatalyst, which would provide the enhanced activity of water splitting reaction as well as stability for long-term operation. This review draws a detailed sketch of the progress in the pursuit of replacing noble metals with non-precious perovskite-based substitutes without compromising the key electrocatalyst characteristics. Herein, we critically analysed the latest research work and progress of perovskite oxides for anodic/oxygen reduction reaction/cathodic, including the mechanism behind perovskite oxide catalytic reactions, controlled composition as well as the role of various design strategies to achieve high catalytic performance. Moreover, the article also provides an insight to the associated density functional theory that can provide profound understanding of mechanism, involved behind these reactions and, the need for computational studies to exploit the active area of catalysts. It is believed that this article will assist researchers to explore key area of research in the current generation perovskites that show enhanced catalytic performance as well as to work on unforeseen challenges.
