| As a sustainable energy conversion technology, direct methanol fuel cells (DMFCs) have shown broad application prospects. The core of DMFC performance optimization lies in the design and improvement of anode catalysts, aiming to efficiently catalyze the methanol oxidation reaction (MOR) and thereby enhance the overall performance of the battery. However, issues such as methanol permeation and catalyst efficiency remain key challenges that restrict its wide application. To address these problems, MXene, a new type of two-dimensional material, has gradually attracted attention. MXene is composed of transition metal carbides, nitrides, or carbonitrides, and this material features high strength, high electrical conductivity, high specific surface area, and hydrophilicity. Moreover, the surface functional groups (-F, -OH) of MXene facilitate the anchoring of metal particles at active sites, making it a competitive carrier for DMFCs. Among them, Ti3C2Tx, as a type of MXene, exhibits multiple significant advantages, such as metallic conductivity, two-dimensional layered structure, small band gap, and hydrophilicity of its functionalized surface. This article summarizes the research progress of Ti3C2Tx MXene-based materials as anode catalysts in DMFCs in recent years and looks forward to their future development and application prospects. |
