“…Cobalt oxide (Co 3 O 4 ) nanostructures with mixed valences (II, III) have been regarded as promising electrocatalysts for OER. Lu et al [100] successfully fabricated 0D Co 3 O 4 /2D Ti 3 C 2 MXene heterojunctions with intimate interfacial coupling and employed as stable, and highly efficient electrocatalysts for OER. Upon activation the overpotential of the hybrid catalyst delivers 300 mV at a current density of 10 mA cm −2 in basic solutions, which is remarkably lower than those of Ti 3 C 2 MXene and Co 3 O 4 nanocubes.…”

The family of transition metal carbides, nitrides, and carbonitrides (collectively called MXenes) has been a thriving field since the first invention of Ti3C2Tx (MXene) in 2011. MXene is a new type of nanometer 2D sheet material, which exhibits great application potentials in various fields due to its multiple advantages such as high specific surface area, good electrical conductivity, and high mechanical strength. Electrocatalysis is regarded as the core of future clean energy conversion technologies, and MXene‐based materials provide inspiration for the design and preparation of electrocatalysts with high activity, high selectivity, and long loading life time. The applications of MXene‐based materials in electrocatalysis, including hydrogen evolution reaction, nitrogen reduction reaction, oxygen evolution reaction, oxygen reduction reaction, carbon dioxide reduction reaction, and methanol oxidation reaction are summarized in this review. As a crucial session regarding experiments, the current safer and more environmentally friendly preparation methods of MXene are also discussed. Focusing on the materials design and enhancement methods, the key challenges and opportunities for MXene‐based materials as a next‐generation platform in both fundamental research and practical electrocatalysis applications are presented. This account serves to promote future efforts toward the development of MXenes and related materials in the electrocatalysis applications.

Similar to graphene and black phosphorus (BP), 2D transition metal carbides and nitrides (MXenes) are of great interest in a variety of fields, such as energy storage and conversion, sensors, electromagnetic interference (EMI) shielding, and photothermal therapy due to their excellent conductivity and hydrophilicity, large specific capacitance, high photothermal effect, and superior electrochemical performance. To further broaden applicable ranges beyond their existing boundaries and fully exploit these potentials, functional 2D MXene nanostructures in recent years have been rationally designed and developed by various approaches, such as doping strategies, surface functionalization, and hybridization, for next-generation devices with the merits of low power consumption, intelligence, and high-integration chips. This review provides an overview of the synthetic routes and fundamental properties of functional 2D MXene nanostructures, including surfacemodified 2D MXenes and mixed-dimensional MXene-based heterostructures, highlights the state-of-the-art progress in the applications of functional 2D MXene nanostructures with regard to energy storage and conversion, catalysis, sensors, photodetectors, EMI shielding, degradation, and biomedical applications, and presents the challenges and perspectives in these burgeoning fields. It is hoped that this review will inspire more efforts toward fundamental research on new functional 2D MXene-based devices to satisfy the growing requirements for next-generation systems.
