Scientists have significantly reduced the CO2-to-CO conversion time from 24 hours to just 15 minutes.
The innovative method uses phthalocyanines applied through a graffiti-like spray technique for efficiency.
This new approach surpasses industrial standards for reaction rate and stability in CO production.
The technology holds potential for broader applications, aligning with global carbon neutrality efforts.The urgent need to combat climate change has propelled scientists worldwide to explore innovative ways of transforming carbon dioxide (CO2) into valuable resources. Among these efforts, the conversion of CO2 into carbon monoxide (CO) is particularly promising, as CO serves as a crucial precursor for creating synthetic fuels. While traditional methods have been bogged down by inefficiencies and high costs, recent breakthroughs have drastically shortened processing times. Researchers from Tohoku University, Hokkaido University, and AZUL Energy have achieved an unprecedented reduction in conversion time, setting the stage for more viable industrial applications.
Revolutionizing CO2 Conversion Methods
The existing CO2-to-CO conversion techniques have been fraught with challenges, such as the use of costly materials, process instability, and lengthy durations that extend up to 24 hours. These hurdles have rendered traditional methods inefficient and impractical for widespread industrial use. However, the researchers introduced a groundbreaking technique utilizing phthalocyanines (Pcs), which are organic compounds commonly used as pigments and dyes. By employing a simple spray method, these Pcs were applied onto gas diffusion electrodes, forming direct crystalline layers on the surface.
This innovative approach not only simplifies the conversion process but also significantly reduces the time required, bringing it down to an astonishing 15 minutes. The use of cobalt phthalocyanine (CoPc) emerged as the most effective, demonstrating exceptional efficiency in converting CO2 to CO. This streamlined, graffiti-like method has proven to be a game-changer, offering a more feasible and sustainable solution for carbon capture and utilization.

Identifying the Best Catalyst for CO Production
The new method’s success extends beyond mere efficiency; it also showcases remarkable stability. The conversion process maintained consistent performance over 144 hours under a current density of 150 mA/cm². This long-term stability indicates the system’s potential for continuous and practical application in industrial settings. The secret to this performance lies in the direct crystallization of phthalocyanines, which results in densely packed molecules. This configuration facilitates the efficient flow of electrons necessary for the conversion process.
Notably, this Pc-based catalyst surpasses the industrial standard thresholds for both reaction rate and stability, marking a significant milestone in CO production technologies. As such, this advancement holds great promise as a next-generation solution for Carbon Dioxide Capture and Utilization (CCU), paving the way for more sustainable fuel production and reduced carbon emissions.
