“Selective CO-to-hydrocarbon conversion in formic acid–promoted borohydride hydrolysis for PEMFC-grade hydrogen production” (Featured)
International Journal of Hydrogen EnergyAugust 2026
Trace CO in the hydrolysis stream is converted into condensable hydrocarbons over Ru/TiO2/Al2O3 — from ~10,000 ppm to under 1 ppm — and the hydrolysis exotherm alone keeps the purifier running.
