Hydrogen Energy Harvesting through nanomaterials under Solar Light Irradiation

In this review, the evolution of hydrogen in combined cell system of Photoelectrocatalytic and microbial fuel disused. Hydrogen is used as chemical fuel. Hydrogen is being produced through Photoelectrocatalytic method. The semiconductor material put into the water and irradiated with solar light after which the hydrogen produced by different steps and accumulated. Production of hydrogen also occur in microbial fuel cell system. These are electrochemical devices that initially used to treat the wastewater. But now this cell has entered into very interesting field of research which is Bioelectrochemical (BES). BES produces hydrogen using biomass as a catalyst using small consumption voltage rather than simple electrolysis of water. The first sections explain how hydrogen is produced individually by these two methods. And then we make comprehensive review on the evolution of hydrogen by combined microbial fuel and photoelectrocatalytic cell system, which is our main motive of writing this article. The continuous production of hydrogen by (PEC-MFC) hybrid device, using sunlight and splitting of water and electrohydrogenesis of microbial cell in fusion device (PEC-MFC) were also reported. This method gives continuous production of hydrogen using wastewater under solar light and also gives the treatment of wastewater. It is the clean energy source and also fulfills the today’s demand of energy. At last, a review on production of hydrogen by microbial photoelectrochemical system which is constructed by photocathode of semiconductor material and an anode of microbial. Production of hydrogen was continuously achieved without external voltage under ultraviolet irradiation.
