Artificial photosynthesis is a chemical process that biomimics the natural process of photosynthesis. The term artificial photosynthesis is used loosely, referring to any scheme for capturing and then storing energy from sunlight by producing a fuel, specifically a solar fuel. [1] An advantage of artificial photosynthesis would be that the ...

1.1 Photosynthesis—Nature''s Primary Way of Storing Energy. All plant matter arises via photosynthesis and is thus stored as solar energy. In oxygenic photosynthesis, the radiant energy of the Sun is captured as chemical bond energy when water (H 2 O) and carbon dioxide (CO 2) is converted into plant matter.

Solar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun''s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of …

Introduction Natural photosynthesis is an amazing machinery perfected by mother nature over many centuries. It is the process by which plants, some bacteria, and some protistas use sunlight as the energy source, CO 2 of the atmosphere, and water as chemicals to carry out two important reactions required for survival and growth of …
