The New Method of Reducing CO2 in the Atmosphere Consists of Reusing the Gas or Converting It to Reduce Its Emission into the Atmosphere

A study conducted by groups from the Center for Development of Functional Materials (CDMF) and the Center for Innovation in New Energies (CINE) is dedicated to finding innovative alternatives to combat the problem of increasing carbon dioxide (CO2) in the atmosphere. The researchers are seeking solutions that allow for the reuse or conversion of CO2 into valuable chemical compounds, aiming to reduce the impact of the greenhouse gas on the environment, according to the website One Planet.

Imitating Nature – Photosynthesis as Inspiration

To tackle the challenge, scientists from CDMF and CINE use nature as a source of inspiration, mimicking natural processes such as photosynthesis. Through advanced studies, they added small amounts of copper oxide to a semiconductor composed of bismuth vanadate and bismuth oxide.

The results were impressive, with several positive effects on the photochemical reduction of CO2. The use of oxide improved charge transfer, mitigated charge recombination, increased visible light absorption, and promoted the production of acetone and methanol.

Transforming CO2 into Valuable Products

The research led by Lucia Mascaro, senior author of the study and researcher at CDMF and CINE, opens new possibilities for capturing CO2 in large quantities, especially in industrial sectors such as oil extraction or steel and hydrogen production.

The use of the photocatalyst enables the transformation of CO2 into valuable organic molecules, with potential to become fuels or other high-value products. One example is acetone, widely used in various industries, including nail polish, paints, varnishes, pharmaceutical manufacturing, and explosives, as well as applications in chemical syntheses.

Methanol also stands out as a solvent in the pharmaceutical industry, fuel for vehicles and airplanes, a raw material for biodiesel and plastics, as well as in the extraction of animal and vegetable products.

Innovation and Sustainability in CO2 Transformation

The research conducted by CDMF and CINE stands out for its innovative approach to combating CO2 emissions by exploring strategies that mimic natural processes such as photosynthesis. The possibility of transforming CO2 into high-value products adds economic and environmental benefits, contributing to the reduction of greenhouse gases in the atmosphere.

This promising initiative may bring sustainable solutions to industrial sectors that are intensive in CO2 emissions, paving the way for a greener and more environmentally conscious future. With the ongoing quest for innovation and sustainability, researchers demonstrate the potential to transform environmental challenges into opportunities for growth and technological development.

The oldest tree in the world, alive since before the birth of Jesus Christ, is cut down in a scientific study and the case changes environmental preservation rules.

Seen from space, an image taken by an astronaut shows an unlikely oasis in the Saudi Arabian desert, protected by a terrain that slows the advance of sand, surrounded by green circles, remnants of an extinct lake and nearly 10,000 years of preserved history.

While in Brazil a 10-story building takes 2 years to complete, in China a company stacks pre-fabricated modules and raises the entire building in just 28 hours and 45 minutes.

An entire island in the Pacific wants to surround itself with a colossal barrier against the ocean to try to escape increasingly violent waves and not be swallowed by the sea in the coming decades.

After ten days orbiting the Moon, science confirms that the astronauts of the Artemis II mission return with altered bodies.

With 7.4 trillion tons of artificial snow pumped in 10 years, an extreme operation could stabilize the West Antarctic ice sheet and prevent a sea level rise of more than 3 meters, but it would require snow cannons, ocean water, and energy on an almost industrial scale at the end of the world.

Peru built a tunnel at an altitude of 4,738 meters cutting through the Andes Mountains, and the road leading to it reaches 4,818 meters, making it the highest paved road in the entire world.

Called Super Mario, the businessman leaves his life on land, spends 25 years living on Royal Caribbean cruises, and spends $100,000 a year to live in a cabin with a balcony in the middle of the sea.

With about 100 meters in length, a capacity of over 800 tons, and operation without ports in combat zones, the new ship of the U.S. Marines emerges as a key piece that could redefine warfare in the Pacific and challenge rival powers.

End of the common gutter: Japanese system with metal chains replaces pipes, transforms rain into a decorative waterfall, and also reduces costs and clogs in installation.

Goodbye, Brazil: Brazilians claim to be ‘oppressed’ and head to Paraguay in search of a ‘right-wing dream’ with 10% taxes, energy up to 2.8 times cheaper, and 23,500 residency applications in 2025.

A 13-year-old boy did what professional archaeologists never managed to do in Berlin by finding a 2,300-year-old Greek coin that proves the ancient Greeks traveled much further than anyone imagined.
