Recent progress in two-dimensional metallenes and their potential application as electrocatalyst

In this article, we looked at metallenes, a novel class of two-dimensional (2D) metals that are attracting interest in the energy and catalysis sectors. Catalysis is one area where their exceptional physicochemical and electrical characteristics might be useful. Metallenes are unique because they include several metal atoms that are not in a coordinated bond. This makes them more active and improves their atomic utilization, which in turn increases their catalytic potential. This article delves into the potential of two-dimensional metals as electrocatalysts for carbon dioxide reduction, fuel oxidation, oxygen evolution, and oxygen reduction reactions in the context of sustainable energy conversion. Owing to the exceptionally high surface-to-volume ratio, large surface area as well as their optimized atomic use efficiency, 2D materials defined by atomic layers are crucial for surface-related sustainable energy applications. Due to its exceptional properties, such as high conductivity and the ability to enhance the exposure of active metal sites, 2D metallenes have recently attracted a lot of interest for use in catalysis, electronics, and energy-related applications. With their highly mobility, adjustable surface states, and electrical structures that can be fine-tuned, 2D metallenes are promising nanostructure materials for use in energy conversion with the sustainable applications.
