Electro-, photo-, and photoelectrocatalysis play a critical role toward the realization of a sustainable energy economy. They facilitate numerous redox reactions in energy storage and conversion systems, enabling the production of chemical feedstock and clean fuels from abundant resources like water, carbon dioxide, and nitrogen. One major obstacle for their large-scale implementation is the scarcity of cost-effective, durable, and efficient catalysts. A family of twodimensional transition metal carbides, nitrides, and carbonitrides (MXenes) has recently emerged as promising earth-abundant candidates for large-area catalytic energy storage and conversion due to their unique properties of hydrophilicity, high metallic conductivity, and ease of production by solution processing. To take full advantage of these desirable properties, MXenes have been combined with other materials to form MXene hybrids with significantly enhanced catalytic performances beyond the sum of their individual components. MXene hybridization tunes the electronic structure towards optimal binding of redox active species to improve intrinsic activity, while increasing the density and accessibility of active sites. This review outlines recent strategies in the design of MXene hybrids for industrially relevant electrocatalytic, photocatalytic, and photoelectrocatalytic applications such as water splitting, metal-air/sulfur batteries, carbon dioxide reduction, and nitrogen reduction. By clarifying the roles of individual material components in the MXene hybrids, we provide design strategies to synergistically couple MXenes with associated materials for highly efficient and durable catalytic applications. We conclude by highlighting key gaps in the current understanding of MXene hybrids to guide future MXene hybrid designs in catalytic energy storage and conversion applications.

“…iii) In addition, the method of the preparation of SACs is well established and the methods commonly used including: 1) wet chemical method, which can achieve optimal loading of TM at adsorption sites on the based materials by adjusting the ratio of reactants, reaction time, type, and amount of surfactant. [ 59 ] For example, a one‐step coprecipitation method reported by experiments to synthesize Ru‐SACs supported on FeCo or FeNi layered double hydroxide (LDH); [ 58,60 ] 2) some preparation techniques via external fields, such as underpotential deposition (Pt‐MoS 2 [ 39b ] ), e‐beam evaporation (Ir‐Fe 3 O 4 [ 39a ] ), etc., are also considered as effective preparation techniques for the preparation of metastable state SACs; 3) the atomic layer deposition (ALD) has also been applied to the preparation of surface‐loaded Pt SA –GNS [ 61 ] and Pt nanoparticle Ti 3 C 2 T x , [ 62 ] which may be a reliable method to prepare TMs–Ti 2 CT x in the S IV adsorption model. Therefore, these combinations of MXene‐based SACs can be alternatives to precious metal catalysts for facilitated synthesis and high‐activity HER catalysts.…”

2D transition metal carbides and nitrides (MXenes) are promising hydrogen evolution reaction (HER) catalysts owing to their metallic conductivity, abundant surface active sites, and high specific surface area. The introduction of a single transition metal atom (TM) at the surface is a good way to improve the HER performance of MXenes. However, the effect of TM on MXenes in previous theoretical studies focused on pure functional groups, and ignored the hybrid‐functionalized ones, which are mostly observed in experiments. Herein, the HER performance of four O/F ratios stable hybrids MXenes, Ti2CTx (T = O, F), is explored. Ti2CO1.33F0.67 exhibits superior HER catalytic activity, comparable to that of platinum metals. Further combinatorial screening of ≈200 TMs based on Ti2CTx structures suggests that Rh, Ti, Ir, and Pt are optimal TM candidates that enhance the sensitivity to strain modulation and reduce the activation barrier for hydrogen generation. A descriptor ψ is used to quantify HER performance and reveals the role of the electron filling of TM to the antibonding orbitals. These findings propose feasible candidates with high HER performance through single‐atom modification for hybrid‐functional MXenes, and a useful descriptor to screen for MXenes with desirable catalytic properties.

“…Experimental and theoretical studies have clearly shown that the catalytic performance of MXene can be adjusted through the interaction of metals and supports. Zhang et al [60] prepared a kind of Pt NPs deposited Ti 3 C 2 T x MXene catalyst with a low Pt content (1.70 wt%) and a small size (≈2 nm in diameter) by atomic layer deposition (ALD) method, which showed excellent HER catalytic activity and stability. The electrochemical results showed that the prepared catalysts exhibited the optimal HER activity as the ALD deposition cycle reached 40, with overpotential of 67.8 mV approaching that of the commercial Pt/C catalyst (64.2 mV).…”

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.
