Fire is a chemical reaction in which energy in the form of heat is produced. When forest fuels burn, there is a chemical combination of the oxygen in the air with woody material, pitch and other burnable elements found in the forest environment. The combustion process or �fire� is sometimes called �rapid oxidation.

The light catalyzes a reaction that creates 2 free radicals, the reaction goes as follows: The reaction does not take place. Hexane has a very stable structure and a lot of energy is needed to break this structure.

Photocatalysis is the activity occurring when a light source interacts with the surface of semiconductor materials, the so called photocatalysts. During this process, there must be at least two simultaneous reactions occurring, oxidation from photogenerated holes, and reduction from photogenerated electrons.

For the first time, chemists have developed a titanium catalyst that makes light usable for selective chemical reactions. It provides a cost-effective and non-toxic alternative to the ruthenium and iridium catalysts used so far, which are based on very expensive and toxic metals.

Chlorophyll is a photoreceptor which absorb light energy from sunlight and transfer it to other molecules present in the reaction centre of photosynthetic apparatus. So, it act as catalyst in the light reaction of photosynthesis as it is not used up in the reaction.

That’s photosynthesis. Energy is now stored and living things can use the carbohydrate to build their bodies and structures. These catalysts are called “enzymes”, photosynthesis also needs a pigment called “chlorophyll”.

Understanding photosynthesis: How plants use catalytic reactions to split oxygen from water. But green plants produce oxygen from water efficiently using a catalytic technique powered by sunlight – a process that is part of photosynthesis and so effective that it is the Earth’s major source of oxygen.

The leaf contains chloroplasts taken from real plant cells, which are suspended in a silk protein material. When this comes into contact with carbon dioxide, water and light, it converts it into oxygen, just like a real plant.

Plants have evolved by using special structures within their cells to harness energy directly from sunlight. Catalysts in the chloroplasts of photosynthesizing plants help split water by binding water molecules and separating protons and electrons.

It is an entirely renewable process; the plant harvests the immense and constant supply of solar energy, absorbs carbon dioxide and water, and releases oxygen. There is no other waste. The process is called artificial photosynthesis, and if the technology continues to improve, it may become the future of energy.

Photosynthesis clearly has us beat when it comes to providing steady energy. Research into better battery technology is essential for all renewable energy sources. Advanced technologies have even been able to achieve efficiencies of up to 40%. These are not practical yet but show that there is a lot of room to improve.

Researchers discovered that plants can generate, by a single leaf, more than 150 Volts, enough to simultaneously power 100 LED light bulbs. Researchers also showed that an “hybrid tree” made of natural and artificial leaves can act as an innovative “green” electrical generator converting wind into electricity.

Artificial photosynthesis, it turns out, is more efficient than natural photosynthesis. “The big difference is that we use artificial, inorganic materials for this, which effectively allow much higher conversion efficiencies,” he added.

Researchers say artificial photosynthesis is needed to clean up atmospheric carbon pollution. Plants are humanity’s greatest ally in the fight against climate change. Plants soak up carbon dioxide and turn it into leaves and branches. The more trees humans plant, the less heat-trapping carbon pollution in the air.

Artificial photosynthesis is a chemical process that biomimics the natural process of photosynthesis to convert sunlight, water, and carbon dioxide into carbohydrates and oxygen. Photocatalytic water splitting converts water into hydrogen and oxygen and is a major research topic of artificial photosynthesis.

Summary: If CO2 emissions do not fall fast enough, then CO2 will have to be removed from the atmosphere to limit global warming. Although artificial photosynthesis could bind CO2 more efficiently than the natural model, huge investments into research are needed to upscale the technology.

Climate change affects plants in many different ways. Increasing CO(2) concentration can increase photosynthetic rates. This is especially pronounced for C(3) plants, at high temperatures and under water-limited conditions. This is likely to increase photosynthetic carbon gain in nutrient-limited systems.

ANOTHER important acquisition to our store of knowledge has recently been made. Glucose, commonly called grape-sugar, has been artificially prepared by Drs. Emil Fischer and Julius Tafel in the chemical laboratory of the University of Würzburg.

Although the technology is not mature enough to be applied to large scale hydrogen production, artificial photosynthesis has a significant potential to lower global water usage and support clean energy systems by generating electricity and hydrogen from photonic energy.
