Abstract
Recently, it has been observed that few drops of water on the surface of oxide materials can generate electricity which is eco-friendly and cost effective. This hydroelectric cell (HEC) may serve as an unconventional source of electrical energy. HEC production cast is very low. Porous SnO2 samples for hydroelectric cell have been prepared by solid-state sintering method. Phase formation and structural analysis of the sample was confirmed by X-ray diffraction pattern using Rietveld analysis. The surface morphology of the sample was determined using field emission scanning electron microscopy. Average grain size of porous sample was depicted 65 nm using image j software. The pore size distribution and specific surface area of SnO2 nanoparticles were examined by the Barrett–Joyner–Halenda technique. A circular pellet having diameter of 2 inch and a square pellet having a side of 2 cm was prepared to study the hydroelectric properties. Peak current value 72.1 mA was observed in circular pellet with almost constant voltage of 0.981 V whereas peak current and voltage values for the square pellet were 12.5 mA and 0.972 V respectively. Dissociation of water and conduction phenomenon have been confirmed using dielectric and DC conductivity behavior of samples.
