Synthesis of mesoporous TiO2 using aloe vera extract for solar cell applications

Abstract

Research has been geared towards the reduction of the cost of fabricating semiconductor materials for solar cells. Biosynthesis of Titanium dioxide (TiO2) has gained scientific attention recently due to its environmentally friendly nature. However, achieving the goal of purely green and sustainable materials is still a challenge. In this study, anatase TiO2 was synthesized from 100 ml aloe vera extract and 4 ml Titanium Tetra Isopropoxide (TTIP). The SEM images showed cluster spherical and irregular shaped particles. The electrochemical results revealed that the TiO2 produced is photoactive. This research reveals that aloe vera plant could be explored for energy sustainability.
