Abstract

Abstract: In this work, TiO2 ‐doped carbon aerogel (TiO2 /CA) was synthesized from sugarcane bagasse hydrothermal, freeze‐drying, and carbonization methods. The effects of the calcination temperatures of 400, 500, 600, 700, and 800 °C were also evaluated. The obtained TiO2 /CA exhibits an ultralow density (0.021‐0.032 g/cm 3 ) and porosity of more than 97 %. The as‐prepared TiO2 /CA was applied in photodegradation of methylene blue (MB) with the effects of dose sample and pH were also investigated. The results show that TiO2 /CA at 800 °C (TiO2 /CA‐800) exhibits the highest MB photodegradation efficiency of 93.86 % at pH 9. The aforementioned results affirm the potential application of sugarcane bagasse for the fabrication of environmentally friendly and low‐cost adsorbents for the photodegradation of MB. Abstract :
