The concept of photosynthesis was understood when the growth of Plants were studied. It is natural process in which sunlight is used to prepare the required nutrient for the plant with the help of The green pigment of plants ,i.e, chlorophyll. However, when the sun sets there is no way that plant can prepare their meal. SO, artificial photosynthesis came into process which emphasizes on receiving most of the energy from the sunlight and meant to effectively accumulate this energy as to utilize in the required duration.
The energy from the sunlight will be transformed into the chemical energy due to which it becomes more suitable for its storage. In this conversion side products are not produced like the greenhouse gases. On the contrary, in the process carbon dioxide can be utilized in the same way as it does in plants.
Plants for this use chlorophyll . It is contained in leaves and captures sunlight, and a set of enzymes and other proteins uses this light to split water molecules into hydrogen, electrons and oxygen (protons). Electrons and hydrogen are used to convert CO2 into nutrients for the plant, and oxygen is released into the atmosphere.
