Deep insights on MXENE-TMC hybrids for energy conversion, storage and photocatalytic hydrogen evolution

The development of advanced materials for energy conversion, storage, and photocatalytic hydrogen evolution is critical to addressing global energy challenges. This article reviews the performance landscape of MXene and transition metal chalcogenides (TMC) hybrids in these applications. In energy storage, MXene/TMC hybrids demonstrate superior electrochemical properties, such as high specific capacity, excellent cycling stability, and fast charge-discharge rates, making them promising candidates for batteries and supercapacitors. For energy conversion, these hybrids show enhanced electrocatalytic performance for reactions like the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), attributed to their efficient electron transport pathways and high intrinsic catalytic activities. Additionally, in photocatalytic hydrogen evolution, MXene/TMC hybrids exhibit significant improvements in hydrogen production rates under light irradiation, benefiting from their broad light absorption range and effective separation of photogenerated charge carriers. The integration of MXenes with TMCs represents a strategic approach to optimize material properties for multifunctional energy applications. The combined advantages of MXenes’ conductive networks and TMCs’ catalytic features lead to enhanced performance metrics across various domains. This review underscores the potential of MXene/TMC hybrids as next-generation materials for sustainable energy technologies and highlights future research directions to further exploit their capabilities.
