Photocatalytic degradation of azo dyes over MXene-based catalyst: Recent developments and future prospects

Dye-induced water pollution is a noteworthy environmental issue, mainly caused by industrial activities that utilize and release effluent-containing dyes, especially azo dyes. One frequently employed large-scale technique for removing dyes from water is photocatalysis degradation. The use of MXene-based catalysts as an advanced material holds promise in overcoming the limitations inherent in previous catalysts due to its expansive surface area and unique tunable properties. The potential of integrating MXene-based catalysts with nanoparticles and semiconductors offers a path to enhance photocatalytic efficiency, create composite materials, promote environmental sustainability, and drive innovations in water purification. Further developments in MXene, including its properties, functional groups, and active sites tailored to semiconductor compatibility, can maximize the capabilities of semiconductors. The rate of photocatalytic reactions stands to improve significantly due to MXene's high light absorption capacity and extensive nanoporous structure. Consequently, MXene-based catalysts in photocatalytic degradation hold the potential to contribute to a more sustainable environment, particularly in water treatment.
