Abstract
In recent years, the development of sustainable and cost-effective electrocatalysts for nitrogen (N2) fixation has garnered significant attention, leading to the introduction of next-generation materials with electrocatalytic properties. Among the most interesting types of these materials, MXenes and their composite forms with their unique properties like high electrochemical activity, large surface area, tunable properties, excellent electrical conductivity, chemical stability, and abundant transition metals have been widely explored. These properties make MXenes promising candidates for various electrochemical reactions, including water splitting, oxygen reduction, hydrogen evolution, N2 activation and reduction, among others. The interface of these materials could be engineered with other entities which can serve as a promising tool for sustainable production of ammonia (NH3) to address the global nitrogen-related challenges. Moreover, optimizing the interfaces between them and reactants is another way to achieve high catalytic activity, selectivity, and stability. Accordingly, this review aims to offer a comprehensive overview of the current state of research in the field of electrocatalytic N2 fixation deploying MXenes and their composites. The highlights comprise progress made in understanding the catalytic properties and unique performances of MXenes for N2 fixation, as well as challenges that persist in this context and the possible solutions that could be implemented to circumvent these challenges in the future.
期刊介绍:
Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
