The researchers develop a system to capture carbon dioxide and convert it into fuel
In an attempt to clean the air from carbon dioxide, which causes the phenomenon of global warming, a scientific team from Auckland University in New Zealand, in cooperation with researchers in Chinese institutions, combined computer chemistry with electrochemical experiments to create a way to create carbon dioxide in formic acid.
This came by developing a system that captures carbon dioxide from the atmosphere and turns it into formal acid and from it into useful chemicals or raw materials such as methanol and ethanol that can be used as fuel.
The new technology depends on the use of electrolysis or electrochemical analysis, by creating a proton exchange membrane in the electrochemical cell, to reduce carbon dioxide in formic acid in an incentive derived from battery waste acids.
This innovation should open exciting capabilities in the future, such as the use of fuel resulting from cars and service stations.
The most dangerous greenhouse gases
Gases are known as global warming, and these gases are found in the planet's atmosphere, the most important of which are carbon dioxide, methane, nitrous oxide, hydrochloroplocarbon, Hydrofluorocarbons, and ozone in the lower layer of the atmosphere.
These gases are characterized by their ability to absorb the infrared that the Earth launches and re-launches, which leads to an increase in the Earth's temperature, thus exacerbating the phenomenon of warming and global warming.
According to the World Meteorological Organization, the main problem lies in the increasing focus of global warming gases, including carbon dioxide, caused by fossil combustion, whether from industrial facilities, station capacity, or transportation, as it is more than 20 billion per year annually. A ton in the Earth's atmosphere, by 0.7 % of the amount of gas naturally in the air
Previous attempts
According to a previous study published by Science Direct, various techniques were developed to deal with the negative impact of high levels of carbon dioxide in the atmosphere, especially the improvement of energy efficiency, detention and use of carbon dioxide, and the development of biological energy (such as algae to capture and reduce carbon dioxide), or Geological insulation by detention and carbon storage in the soil and oceans, or "the use of renewable energy sources that do not emit carbon dioxide (such as solar energy and wind energy), in addition to creating roads and ways to get rid of carbon dioxide in converting into useful materials.
Among these questions, there is the conversion of carbon dioxide into formal acid, with the possibility of using it for transportation and energy storage, which will lead to reducing the industry of petrochemical dioxide and its concentration in the atmosphere, which makes this process a phrase the need to deal with global environmental challenges
Electrolysis
Electricity analysis in chemistry and industry is how an electric current is used to release a chemical reaction, using the electrochemical analysis unit, and this process is important in separating elements of their forms in nature such as metals. Chemical analysis is also used to prepare materials difficult to prepare with chemical averages or due to the high costs of chemical methods, and examples are present in the preparation of aluminum, chlorine, and the hydroxide solution pure sodium.
It is often used in the electrochemical analysis process a stimulating substance, which is a chemical added in small quantities of chemical reaction to accelerate the reaction without changing the properties of chemicals, which means that it is capable of 'Increasing the speed of the chemical reaction by reducing the energy of the reaction or by activating it without chemical change which occurs with it permanently.
According to a study published by Patrol Nature, electrical analysis - which reduces carbon dioxide to useful chemicals - can contribute to a more durable future and reduce the concentration of carbon dioxide in the atmosphere.
However, there are still problems faced with the process of reducing carbon dioxide by electrolysis, including the difficulty of depositing carbon dioxide in the form of carbonate. To solve this problem, the researchers have developed the proton exchange system which reduces carbon dioxide in formic acid during the electrochemical analysis process by fueling carbon dioxide in the electrochemical cell and converting it into formic acid and it in fuel, as is the load of the battery, using a catalyst made of acid lead waste batteries, which allowed a change which was not possible before.
Scientists believe this process can be widened for industrial use effectively and with potential applications in cars, service stations, and the petrochemical industry. This technology can help a carbon-free economy and reduce greenhouse gas emissions.
