Electrochemical water splitting for hydrogen generation is considered one of the most promising strategies for reducing the use of fossil fuels and storing renewable electricity in hydrogen fuel. However, the anodic oxygen evolution process remains a bottleneck due to the remarkably high overpotential of about 300 mV to achieve a current density of 10 mA cm−2. The key to solving this dilemma is the development of highly efficient catalysts with minimized overpotential, long‐term stability, and low cost. As a new 2D material, MXene has emerged as an intriguing material for future energy conversion technology due to its benefits, including superior conductivity, excellent hydrophilic properties, high surface area, versatile chemical composition, and ease of processing, which make it a potential constituent of the oxygen evolution catalyst layer. This review aims to summarize and discuss the recent development of oxygen evolution catalysts using MXene as a component, emphasizing the synthesis and synergistic effect of MXene‐based composite catalysts. Based on the discussions summarized in this review, we also provide future research directions regarding electronic interaction, stability, and structural evolution of MXene‐based oxygen evolution catalysts. We believe that a broader and deeper research in this area could accelerate the discovery of efficient catalysts for electrochemical oxygen evolution.

“…X denotes the element carbon (C) and/or nitrogen (N), while T signifies several chemical groups, including –OH, –O, –Cl, and –F. , The 2D transition-metal carbides (2D MXenes) exhibit a combination of exceptional metallic conductivity, remarkable hydrophilicity, and a wide range of chemical functionalization capabilities on their surfaces . Because of these advantages, MXene is particularly promising in a wide range of applications, including energy storage, catalysis, − transparent electronic devices, separation membranes, sensors, reinforcement for composites, electromagnetic shielding, and biomedicine. − Van der Waals attraction and hydrogen bonds, however, also contribute to MXene’s great tendency for intersheet aggregation. The aforementioned limitation gives rise to a decline in performance due to the reduction in surface area and challenges in the processability of materials based on MXene. , This issue may be effectively solved by adding interlayer spacers, such as polymers, nanoparticles, big ions, nanotubes, or even gaseous species, between MXene nanosheets. ,,− The utilization of a 3D MXene frame, which possesses exceptional conductivity and hydrophilic characteristics, serves to improve the kinetics of charge transfer and the adsorption/activation of water molecules on electrocatalysts.…”

Due to its affordable cost, excellent redox capability, and relatively effective resistance to corrosion in alkaline environments, spinel Co 3 O 4 demonstrates potential as a viable alternative to noble-metal-based electrocatalysts. Nevertheless, these materials continue to exhibit drawbacks, such as limited active surface area and inadequate intrinsic conductivity. Researchers have been trying to increase the electrical conductivity of Co 3 O 4 nanostructures by integrating them with various conductive substrates due to the low conductivity of pristine Co 3 O 4 . In this study, uniform cobalt glycerate solid spheres are first synthesized as the precursor and subsequently transformed into cobalt oxide microspheres by a simple annealing procedure. Co 3 O 4 grown on the surface of Ti 3 C 2 T x -MXene nanosheets (Co 3 O 4 /MXene) was successfully synthesized through electrostatic attraction. In order to create a positively charged surface, the Co 3 O 4 microspheres were treated with aminopropyltriethoxysilane. The Co 3 O 4 /MXene exhibited a low overpotential of 118 mV at 10 mA cm −2 and a Tafel slope of 113 mV dec −1 for the hydrogen evolution reaction, which is much lower than the pristine Co 3 O 4 at 232 and 195.3 mV dec −1 .

Developing efficient electrocatalysts is significant for the commercial application of electrocatalytic water splitting. 2D materials have presented great prospects in electrocatalysis for their high surface‐to‐volume ratio and tunable electronic properties. Particularly, MXene emerges as one of the most promising candidates for electrocatalysts, exhibiting unique advantages of hydrophilicity, outstanding conductivity, and exceptional stability. However, it suffers from lacking catalytic active sites, poor oxidation resistance, and easy stacking, leading to a significant suppression of the catalytic performance. Combining MXene with other 2D materials is an effective way to tackle the aforementioned drawbacks. In this review, the focus is on the accurate synthesis of 2D/2D MXene‐based catalysts toward electrocatalytic water splitting. First, the mechanisms of electrocatalytic water splitting and the relative properties and preparation methods of MXenes are introduced to offer the basis for accurate synthesis of 2D/2D MXene‐based catalysts. Then, the accurate synthesis methods for various categories of 2D/2D MXene‐based catalysts, such as wet‐chemical, phase‐transformation, electrodeposition, etc., are systematically elaborated. Furthermore, in‐depth investigations are conducted into the internal interactions and structure‐performance relationship of 2D/2D MXene‐based catalysts. Finally, the current challenges and future opportunities are proposed for the development of 2D/2D MXene‐based catalysts, aiming to enlighten these promising nanomaterials for electrocatalytic water splitting.
