Semiconductor nanoparticles based photocatalysis process considered as the best means for mitigation of noxious dyes. To this end, present work focused on the removal of Coralline Red dye using green synthesized Titanium dioxide nanoparticles (TiO2NPs) prepared from Phyllanthus Emblica (Amla) leaves extract. Synthesized NPs were characterized by pertinent chemical analysis and microscopy tools, which confirmed that the formation of crystalline, spherical with size range of 20–30 ​nm with small aggregates. Furthermore, synthesized TiO2 showed appreciable photocatalytic degradation potential for Coralline Red dye under solar light with apparent rate constant (kapp) and degradation efficiency of 0.005 min−1 and ~93% respectively. Therefore, the current study provides the new insights in the research of green chemistry for making an effective, cost-effective and sustainable platform for water purification.
