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.
