Exploring the potential of MXene-based advanced solar-absorber in improving the performance and efficiency of a solar-desalination unit for brackish water purification

Brackish water desalination using solar still (SS) is a low-cost sustainable solution to global scarcity, but this technology suffers from low yield and efficiency. The judicious amalgamation of highly conductive materials with superior absorption behavior one the most effective approaches overcome limitation. In regard, present work synthesizes novel multilayered 2-D MXene 3-D MAX phase as coating material for absorber SS improve its performance. Two different loadings (0.05 0.1 wt%) were dispersed in turpentine oil/black paint (1:4) coated onto SS. Higher loading significantly augmented thermal conductivity absorptivity solution. wt% provided higher heat transfer rate water, leading 6% increase temperature total 2.07 kg. theoretical calculated was identical experimental deviation ±5%, demonstrating accuracy modelling. average energy efficiency black 36.31%. Water quality analysis has shown that distilled resulting suitable drinking. conclusion, excellent thermo-physical properties will be beneficial development efficient units performance purification.
