Special Issue Information

Dear Colleagues,

Catalysis in an enabling technology used to promote sustainability, environment, energy, health, and quality of life. In addition to promoting the feasibility, eco-efficiency, and economics of over 90% of chemical processes, catalysis is a critical element associated with sustainability in many chemical industry fields, from mobility (catalytic converters in vehicles, cleaner fuels, better lubricants, etc.) to a wide range of emission clean-up technologies (DeNOx for power plants, etc.).

This Special Issue aims to collect high-quality review articles in the field of catalysis, for which the Editorial Board Members of the journal Catalysts, Section “Catalysis for Sustainable Energy”, and other researchers working in the field, are cordially invited to contribute. Review articles dealing with homogeneous and heterogeneous, as well as photo-, electro-, and enzymatic catalytic processes, directed to energy and/or renewable fuel production and use in a sustainable manner (employing both theoretical and experimental tools) are welcome.

The utilisation of fossil fuels has resulted in the continuous increase in anthropogenic carbon dioxide (CO2) emissions and has led to significant environmental impacts. To this end, the catalytic hydrogenation of captured CO2 into value-added C1 chemicals has attracted great attention. In this case, significant research efforts have been directed towards the development of heterogeneous catalysts. Owing to the unique properties and functionalities of hydridic hydrogen (H−), metal hydrides have shown great promise in hydrogen-involved catalytic processes. This is attributed to their enhanced hydrogen (H2) absorption-desorption reversibility and newly developed active sites. Nevertheless, their application in the activation and hydrogenation of CO2 has been overlooked. In this review paper, we provide an overview of recent advances in catalytic CO2 hydrogenation using metal hydride-based materials. Firstly, the reaction mechanisms of CO2 hydrogenation toward different C1 products (CO, CH4, CH3OH and HCOOH) are introduced to better understand their application trend. Thereafter, we highlight the challenges of developing robust hydride catalysts with different components and structures that enable tuning of their catalytic activity and selectivity. A brief introduction of the CO2 hydrogenation over typical homogeneous metal hydrides complexes is also presented. Lastly, conclusion, future outlook and perspectives are discussed. Full article

The increasing concentration of carbon dioxide (CO2) in the atmosphere is a significant contributor to global warming and climate change. Effective CO2 capture and storage technologies are critical to mitigating these impacts. This review explores various materials used for CO2 capture, focusing on the latest advancements and their applications. The review categorizes these materials into chemical and physical absorbents, highlighting their unique properties, advantages, and limitations. Chemical absorbents, such as amine-based solutions and hydroxides, have been widely used due to their high CO2 absorption capacities and established technological frameworks. However, they often suffer from high energy requirements for regeneration and potential degradation over time. Recent developments in ionic liquids (ILs) and polymeric ionic liquids (PILs) offer promising alternatives, providing tunable properties and lower regeneration energy. Physical absorbents, including advanced solvents like nanofluids and ionic liquids as well as industrial processes like selexol, rectisol, and purisol, demonstrate enhanced CO2 capture efficiency under various conditions. Additionally, adsorbents like activated carbon, zeolites, metal-organic frameworks (MOFs), carbon nanotubes (CNTs), and layered double hydroxides (LDHs) play a crucial role by providing high surface areas and selective CO2 capture through physical or chemical interactions. This paper summarizes the state of research on different materials and discusses their advantages and limitations while being used in CO2 capture technologies. This review also discussed multiple studies examining the use of catalysts and absorption mechanisms in combination with different sorbents, focusing on how these approaches enhance the efficiency of absorption and desorption processes. Through a comprehensive analysis, this review aims to provide valuable insights into the type of materials that are most suitable for CO2 capture and also provides directions for future research in this area.

Biodiesel has received tremendous attention as a sustainable energy source. This review presents an overview of various catalysts utilized in biodiesel production and compares their potential for producing biodiesel. Presented here are the excellent features of the various catalysts while highlighting their drawbacks. For instance, production of biodiesel with homogeneous base catalysts is easy but it can only be used with refined oils having low levels of free fatty acid (FFAs). When homogeneous acid is used in esterification, it causes reactor corrosion. Water and FFAs do not affect heterogeneous acid catalysts. Thus, transesterification of triglycerides into biodiesel and converting FFAs into biodiesel through esterification can be catalyzed more efficiently using a heterogeneous acid catalyst. Biocatalysts are also being used to produce biodiesel from oils with high FFAs. However, heterogeneous acid catalysts and biocatalysts are not suitable for industrial application due to serious mass transfer limitations. Biodiesel yield and conversion were compared over various catalysts in this paper. Also presented are the effects of different reaction parameters on biodiesel yield over different catalysts. The correct interplay of factors like reaction temperature, time, alcohol-to-oil molar ratio, and catalyst loading produces optimal process conditions that give the highest biodiesel yield.
