In fact

In fact, it was a fuel cell produced during one of the stages of photosynthesis, namely the one in which photons collide with chlorophyll, contributing to the ejection of electrons. Discovery is a source of cheap energy from water and chlorophyll, as well as a source of hydrogen, which is considered an ideal fuel. At the same time, it represents an important step towards the artificial synthesis of organic substances (carbohydrates and fats).

Photosynthesis is a process in which, using light as an energy source, plants are synthesized from carbon, derived from simple inorganic substances (carbon dioxide), complex organic substances. The operation takes place in specialized cellular organelles called chloroplasts, which contain the necessary green pigment – chlorophyll. The process is extremely complex.

In the first stage of photosynthesis, chlorophyll absorbs photons of light from solar radiation and, in response, produces an equivalent number of electrons. These electrons lead to the formation of enzymes necessary for the subsequent stages of photosynthesis. Chlorophyll recovers electrons in water molecules during a process called photolysis of water, which takes place with the participation of one of the previously formed enzymes catalyzed by structures containing manganese and calcium atoms. Water molecules are split into hydrogen and oxygen ions; hydrogen participates in chemical reactions leading to the formation of ATP molecules, and oxygen is released into the atmosphere and used by countless organisms for breathing.

In the second stage, plants absorb carbon dioxide from the atmosphere and, using a series of enzymes in a chain of complex operations, build carbohydrates such as sucrose or starch from carbon extracted from CO2, and from them other organic substances.

In this process, its effectiveness is important: almost nothing is lost, biochemical cycles work with great speed and accuracy, which seem implausible, enzymes are constantly being processed and regenerated.

Photosynthesis is a phenomenon that, despite being studied to the last detail, is still a miracle.

Recently, a group of researchers from the Massachusetts Institute of Technology (MIT), led by Professor Daniel H. Nocera, announced that she received what they call the “first artificial leaf”: a mini-sized solar panel the size of a playing card, inexpensive, stable and resistant to wear semiconductor material coated with catalyst compounds, which when immersed in water, simulates the process of photosynthesis with a high degree of efficiency.
