A Review on MXene Synthesis, Stability, and Photocatalytic Applications

ACS Nano, Journal Year: 2022, Volume and Issue: 16(9), P. 13370 - 13429

Published: Sept. 12, 2022

Photocatalytic water splitting, CO2 reduction, and pollutant degradation have emerged as promising strategies to remedy the existing environmental energy crises. However, grafting of expensive less abundant noble-metal cocatalysts on photocatalyst materials is a mandatory practice achieve enhanced photocatalytic performance owing ability extract electrons efficiently from enable rapid/enhanced catalytic reaction. Hence, developing highly efficient, inexpensive, noble-metal-free composed earth-abundant elements considered noteworthy step toward considering photocatalysis more economical strategy. Recently, MXenes (two-dimensional (2D) transition-metal carbides, nitrides, carbonitrides) shown huge potential alternatives for cocatalysts. several excellent properties, including atomically thin 2D morphology, metallic electrical conductivity, hydrophilic surface, high specific surface area. In addition, they exhibit Gibbs free intermediate H atom adsorption close zero than that commercial Pt-based cocatalyst, Fermi level position above H2 generation potential, an capture activate molecules. Therefore, there growing interest in MXene-based various events. this review, we focus recent advances synthesis with 0D morphologies, stability MXenes, photocatalysts evolution, degradation. The challenges possible future directions enhance are also discussed.
