Nanoscale cadmium stannate (CdSnO3) structures were productively synthesized via a facile and rapid sonochemical route using an eco-friendly capping agent of glucose. In order to optimize the size and structure of products, the various effective factors were inquired such as ultrasound waves, calcination temperature and solvent. The all samples were synthesized under ultrasonic probe for 30 min and different power (frequency) of 80 (24 KHz), 60 (18 KHz) and 40 W (12 KHz). The properties and characteristics of as-fabricated samples were examined by proficient techniques to identification the purity, structure, shape, optical, electrical and surface features. The ability of CdSnO3 nanostructures and representative graphene based nanocomposites as potential hydrogen storage materials was considered by electrochemical methods. According to the obtained results, the CdSnO3/graphene nanocomposites demonstrated higher hydrogen storage capacity than pristine CdSnO3 nanostructures.
