Artificial Photosynthesis And how it is created

Photosynthesis is the process in which a plant creates its own food called glucose. Photosynthesis has been around for more than 2 billion years. Glucose is sugar that is created with water and Carbon Dioxide. Then the sun's energy is processed to make Oxygen and Glucose. This whole process happen in the chloroplast. The Oxygen is released into the which we breath in. The plant obtains the Carbon Dioxide from the organism that breath out Carbon Dioxide after breathing in Oxygen.

People used to believe that only birds and other creates with wing that had the capability to fly. Yet here we are today with airplanes and other inventions that help us to move through the air. This is what people believe with photosynthesis that only plants can create it. Photosynthesis is something that scientist are trying recreate without using plants they have done many attempts to recreate photosynthesis there are three main challenges of recreating photosynthesis is light capture, water splitting- also known as catalysis, and carbon dioxide reduction. The hardest challenge of the three is recreating how photosynthesis takes out the carbon from the atmosphere. But using nanotechnology can help us create artificial photosynthesis. Once the problems are solved creating artificial photosynthesis won't be hard to create. When artificial photosynthesis is created it won't only replicate it but it will also be improving it using the nanotechnology involved in it. Creating artificial photosynthesis can reduce the amount of carbon dioxide in the air and other problems we have in our world today it will also provide fuel, food, and fertilizer.

There are large groups of scientists and chemists around the world studying photosynthesis and how to recreate it including places like the USA, Europe, and Japan. But this study might cause problems between each group due to the lack of some kind of supply in that certain area. One big goal for artificial photosynthesis is to create fresh water in the process. A hope that the world has with artificial photosynthesis is to plant plants along the sea line to use the sea water to create energy for cities. Using desert plants will help because desert plants can create better fresh water than other plants in the world. This kind of energy is not the only one that can be used in cities the artificial energy can also be used in the cities. This kind of energy is not harming to the environment either.

Peidong Yang was the first person to discover how to create artificial photosynthesis. It took him and his group more than ten years to create the first run. He used semiconductors and live bacteria to do what a plant does during photosynthesis take in energy and use water and carbon dioxide. Then release the oxygen creating a liquid fuel. If our technology gets better in the future this this- Artificial Photosynthesis- can become the energy that the future needs.

Peidong Yang

Yang used semiconductors and living bacteria. Semiconductors are not the same as solar panels. Unlike solar panels semiconductors store the solar energy instead of creating it into electronic energy. The artificial photosynthesis is created by dipping in a tray of the semiconductors and bacteria into water, then he pumps in carbon dioxide in the water, then shining a solar light on it. The semiconductors collect the solar energy, the bacteria then takes the electrons from the semiconductors, transforming the carbon molecules into liquid fuels the water is in a different semiconductor which then releases oxygen. This process take many hours even days to complete. The chemist then collect the results and product.

This is a diagram of what happens when Yang is Creating Artificial Photosynthesis

Businesses then can create artificial forests that produce fuel for planes, cars, power plants, even boats using the liquid fuel without harming the environment. The problem is that the artificial photosynthesis isn't durable enough or cost-efficient and this artificial photosynthesis uses concentrated carbon dioxide which is different than what natural photosynthesis uses. Many problems would go away if artificial photosynthesis could be included in engineering structures which would provide cheap sources of soil nutrients, carbon dioxide, hydrogen fuel, and oxygen

Another benefit of artificial photosynthesis is hydrogen. Hydrogen can be released with artificial photosynthesis. The hydrogen could be used as a source of electricity or a liquid fuel or it could be mixed with carbon dioxide to create fuels like methanol but getting hydrogen costs a lot of money. Artificial Photosynthesis is an important opportunity to power and feed the world hopefully in the future the world will be better and not have all the problems we have right now using artificial photosynthesis.
