“…In consideration of the crystallization techniques, the bottom‐up growth of secondary phase on MXene mainly relied on the increase of oversaturation. Recently, Wu and co‐workers loaded Pt nanoparticles on Nb 2 CT m MXene by an incipient‐wetness impregnation (IWI) method . The repeated instilment and desiccation process produced precipitation of Pt precursor on the surface of Nb 2 CT m MXene.…”

In recent years, the rapidly growing attention on MXenes makes the material a rising star in the 2D materials family. Although most researchers' interests are still focused on the properties of bare MXenes, little attention has been paid to the surface chemistry of MXenes and MXene‐based nanocomposites. To this end, this Review offers a comprehensive discussion on surface modified MXene‐based nanocomposites for energy conversion and storage (ECS) applications. Based on the structure and reaction mechanism, the related synthesis methods toward MXenes are briefly summarized. After the discussion of existing surface modification techniques, the surface modified MXene‐based nanocomposites and their inherent chemical principles are presented. Finally, the application of these surface modified nanocomposites for supercapacitors (SCs), lithium/sodium–ion batteries (LIBs/SIBs), and electrocatalytic water splitting is discussed. The challenges and prospects of MXene‐based nanocomposites for future ECS applications are also presented.

“…Although metal–support interactions (MSIs) have been known to play substantial roles in the catalytic active sites, effect of MXenes as supports for metal nanoparticles (NPs) catalysts remained unclear. Our previous work reported reactive metal–support interaction (RMSI) in Nb 2 CT x MXene supported platinum catalysts . RMSI refers to a chemical reaction that occurs at the interface between the supported NPs and their supports, often leading to the formation of bimetallic structures.…”

MXenes, a bourgeoning class of 2D transition metal carbides, are of considerable interest in catalysis due to their rich surface chemistry, tunable electronic structures, and thermal stability. Here, recent conceptual advances in applying MXenes and their nanocomposites in (photo)electrocatalysis and conventional heterogeneous catalysis are highlighted. In addition, the nature of active sites in the MXene‐based catalysts are discussed and the significance and challenges in the future development of catalysts using MXenes as the platforms are summarized.

Developing highly active, non‐noble‐metal H2‐evolution catalysts is appealing yet still remains a great challenge in the field of electrocatalytic and photocatalytic H2 production. In this work, high quality transition‐metal carbonitrides M3CN (MXene) are investigated using well‐defined density functional theory (DFT) calculations. The structural configurations, H‐adsorption free energy (ΔGH) and charge transfer for bare, surface‐terminated and transition‐metal (TM)‐modified M3CNO2 are systematically studied. The calculated results indicate that all bare transition metal carbonitrides exhibit strong binding between H atom and catalysts. In addition, only Ti3CNO2 and Nb3CNO2 have the potential to be HER active catalysts based on the ΔGH results. In an attempt to overcome poor HER activity limitations, we apply O as well as OH mixed groups and TMs modification on the Ti3CNO2 surface for tuning HER activity, and a significant improvement of HER activity is observed. Overall, this work presents in‐depth investigations for transition‐metal carbonitrides (MXene) and opens up new designs for robust metal carbonitrides as noble‐metal‐free cocatalysts for highly efficient and low‐cost MXene‐based nanocomposites for water splitting applications.
