Brazilian Scientists Develop Catalyst for 100% Ethanol to Hydrogen Conversion
Researchers at Brazil's Ipen have developed a ceramic catalyst that achieves 100% conversion of ethanol to hydrogen, enhancing renewable fuel efficiency. The catalyst demonstrates stability for up to 85 hours, yielding 4.04 moles of hydrogen per mole of ethanol. This advancement is significant amid the push for clean energy solutions and aims to reduce reliance on precious metals, utilizing more abundant nickel instead. The findings are published in the International Journal of Hydrogen Energy.

Scientists from Brazil's Ipen have developed a ceramic catalyst that significantly improves the conversion of ethanol to hydrogen, achieving 100% conversion and yielding 4.04 moles of hydrogen per mole of ethanol. The catalyst maintains operational stability for 85 hours with low carbon formation.
The research, published in the International Journal of Hydrogen Energy, indicates that controlling the calcination temperature of the precursor oxide is crucial for performance. Using nickel instead of noble metals reduces costs and enhances the economic viability of hydrogen production. This development supports Brazil's strong ethanol production infrastructure and offers a path towards decentralized hydrogen production and low-carbon industrial applications.
