The need to treat wastewater and prevent the release of hazardous substances into the environment has increased because of growing environmental awareness. New compounds, most of which are not biodegradable, have emerged due to rising consumer expectations. Due to their distinctive chemical and physical characteristics, MXene has lately been recognized as an exciting option. The strong hydrophilicity of MXene makes them a promising candidate for environmental remediation methods like photocatalysis, natural chemical nature, and powerful electrochemistry—adsorption, membrane separation, and electrocatalytic sensors for identifying pollution. MXene has strong surface functional groups, an ion exchange property, and an extremely hydrophilic surface. The most recent developments in MXene preparation and characterization for (Ti C Tx) based nano photocatalysts for water remediation and applications are summarized in this review. Additionally, there are difficulties associated with the synthesis and application of MXene for examining and discussing pollution decontamination. This emerging field focuses on utilizing MXene materials to address water pollution issues through photocatalytic processes. Challenges in designing effective MXene-based photocatalysts are explored, including issues related to charge carrier separation, electron transfer dynamics, and optimizing catalytic efficiency. Recent developments and innovative strategies for overcoming these challenges are discussed, highlighting advancements in enhancing photocatalytic performance and improving water remediation capabilities. The synopsis aims to provide a concise overview of the current state of MXene-based nano photocatalysts for water treatment, offering insights into both hurdles and promising breakthroughs in this critical area of environmental research.
