Safe, Efficient and Portable Power Generation in Oxide Based Hydroelectric Cells by Water Splitting

Hydroelectric cell is a new green source of energy which uses only water for electricity generation without any harmful effects to the environment. Lithium doped magnesium ferrites and tin oxide samples were prepared by solid state sintering method for the green energy production. The XRD pattern of the magnesium lithium ferrite (MLFO) sample confirmed the spinel phase formation and for the SnO2 sample, the pattern exhibited tetragonal structure without any impurity. Surface morphology of MLFO and SnO2 sample was observed by using Scanning Electron Microscopy (SEM) which confirmed the porous nature of the samples with randomly oriented crystalline nature. Adsorption of water and its splitting process over the surface of metal oxides plays key role in production of electricity. The creation of metal–oxygen or metal-hydroxyl bonds are due to thermodynamic driving force and results in dissociation of water molecules in ions (H3O+, OH−). These ions move towards respective electrodes. Hydroelectric cell having diameter 5 cm was designed for both the samples using silver and zinc plates as electrodes. The MLFO cell produced 17.0 mA of highest peak current and highest peak voltage of 950 mV with highest output power with value 16.15 mW whereas for the SnO2 cell showed a maximum current and voltage of 72.1 mA and 981 mV respectively with maximum output power of 70.7 mW.
