ABSTRACT=<p>Solar water interfacial evaporation (SWIE) has attracted much attention for harvesting clean water. Over the last few decades, researchers have developed an innovative photo-thermal material for high-performance solar water interfacial evaporation. For higher evaporation performance, TiO<sub>2</sub>-based materials gain attention as a promising photo-thermal material due to their light absorption capacity. This study compared conceptual designs of TiO<sub>2</sub>-based materials for SWIE. Structural design and engineering strategies for improving evaporation rates and higher thermal conversion efficiency were reviewed. In addition, the material’s thermal stability and heat management were analyzed. This review provides an overview of the current advances in photo-thermal TiO<sub>2</sub> materials to motivate research and translation efforts from the laboratory to large-scale solar water clean water production. Additional benefits of TiO<sub>2</sub> materials on solar water interfacial evaporation should be investigated beyond containers to solve interconnected water, environmental, and energy progression.</p>
