HIGHLIGHTS • Good MXENE stability and possibility of its regeneration for long-term applications. • Importance of scavenging tests and proper identification of radical species in the process. • Degradation studies must be evaluated, including the final mineralization rate of the pollutant. • Optimization of pollutant concentration must include the aspect of photocatalyst capacity. • Controversial, not confirmed, conclusions about CO2 formation during treatment.en© 2025 The Authors.
