- Abstract
- Methanol reforming for hydrogen production has drawbacks:high-temperatureoperation (>200 & DEG;C) and carbon monoxide (CO) generation. Aheterogenizedcatalyst based on ruthenium, containing an active site of a homogeneousorganometallic catalyst, was employed to perform aqueous-phase reformingof methanol at a low temperature (90 & DEG;C). The catalyst exhibitedan outstanding productivity of up to 115 & mu;mol H-2 g(cat.) (-1) s(-1), without anyCO generation, and demonstrated 10 times recyclability. This approachoffers a promising alternative to address challenges in hydrogen production,including CO by-product generation and temperature limitations, particularlyin fuel cell applications. HeterogenizedRu-MACHO shows high H-2 productivity(115 & mu;mol H-2 g(cat.) (-1) s(-1)) in the aqueous-phase reforming of methanolat low temperature and without CO.
