Ti3C2 MXene as an Efficient Electrocatalyst for Hydrogen and Oxygen Evolution Reactions

The utilization of two-dimensional (2D) materials has garnered significant attention in addressing society’s energy needs by exploring their properties that include unique chemical, structural, and electronic advances along with the larger quantity of active sites, and superior conductivity. Among these materials, MXenes, an emerging 2D transition metal carbonitrides, carbides, and nitrides stand out because of the potential advantage of metallic conductivity, tunable hydrophilicity, surface termination, and optical band gap. In this overview, we delve into the electrocatalytic applications of MXenes, offering insights into their synthesis, mechanisms, and efficacy in both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), both individually and when incorporated into composites and heterostructures. Finally, the future aspects of MXenes explain how the materials open up the ways for enhancing the catalytic activity through their advanced synthesis and surface functionalization strategy. Looking ahead, refining synthesis methods and tailoring surface properties, researchers can further optimize MXene materials for enhanced catalytic activity and durability. Overall, MXenes hold great promise as catalysts for sustainable energy technologies, offering pathways toward a cleaner and more efficient energy future.
