Abstract

Monoclinic molybdenum dioxide (MoO2) nanosheets have been successfully synthesized by a simple electrochemical method. The as prepared MoO2 was used as a photocatalyst for the photocatalytic degradation of Indigo carmine dye under various experimental conditions and also as oxygen evaluation catalyst for the decomposition of potassium permanganate. Initially, as-prepared MoO2 was characterized by different techniques namely, X-ray diffraction, scanning electron microscopy FE-SEM, UV-visible and FT-IR techniques, so as to study and revealed the morphological, structural, functional and optical properties. The results revealed that photocatalyst has nanosheets morphology with thickness less than 10 nm and it has also monoclinic crystal structure with an average crystallite size of 27 nm. The optical properties studies showed that band gap (Eg) value of MoO2 (3.85 eV) lies in the UV region and can be a suitable candidate for UV light photocatalytic application. In addition, the experimental results revealed an excellent photocatalytic performance of MoO2 in the degradation of Indigo carmine under UV light irradiation and also for the decomposition of KMnO4 by oxygen evaluation reaction.
