Abstract

The transition towards supercapacitors for efficient energy storage provides a dynamic outcome for the global warming. The MoO₃ samples were prepared at various pH using facile wet-chemical approach. The orthorhombic phase (α-MoO₃) was confirmed from structural investigations namely XRD, and Raman. It is also evident that the prepared samples show layered structure of MoO₃, which contributed in improving the efficiency of the supercapacitor application. The morphological analysis from SEM micrographs showed a slight agglomeration. The CV studies revealed that the sample prepared at pH-10 displayed a higher specific capacitance.
