Copper-based MXenes: Synthesis, Properties and Applications

Abstract

Abstract: Great results are emerging subsequently from the isolation and characterization of graphene and have resulted in increasing interest in two-dimensional (2D) materials that are different from their three-dimensional (3D) analogues. Over the past decade, science-inclined researchers have invested in the synthesis of novel MXenes with combined transition metals forming a compound of the MAX phase family. MXenes, a derivative of MAX phase is a class of novel two-dimensional (2D) transition metal containing carbide/nitride with a Mn+1AXn formula. Due to their unique physical, electronic, chemical, and structural properties, it has been utilized in the membrane, adsorption, and separation technique, respectively. Additionally, due to their surface reactivity, adsorption ability, and hydrophilicity, MXenes have revealed broad application prospects such as sensors, metal-ion batteries, environment, and catalysis. Although several works have been carried out and are still on-going in this area, copper-based MXenes are rare class of MXenes. In this review, we provide an overview of preparation, properties and applications of Copper-based MXenes reported in literature.
