In this contribution, we present a comprehensive study of MXene-based materials across three key catalytic domains: photocatalysis, thermal catalysis, and electrocatalysis.
In photocatalysis, we demonstrate that controlling the size and surface terminations of MXenes enables the transition from metallic to semiconducting behavior, allowing their use either as standalone photocatalysts or as cocatalysts in heterojunction systems.
For thermal catalysis, we exploit the intrinsic similarities between MXene surface terminations (–O, –OH, –F) and classical metal oxide active sites (e.g., Ti–OH, Nb=O), while introducing a distinct electronic environment arising from the underlying C/N framework.
In electrocatalysis, MXenes exhibit outstanding performance due to their high electrical conductivity, hydrophilic surfaces, and ability to form hybrid structures with metals and porous materials. We highlight the role of MXene-based heterostructures in enhancing charge transfer and catalytic efficiency in reactions such as hydrogen evolution and CO₂ reduction.
