Hydroxyl-rich catalysts enhance hydrogen release efficiency from methanol

A research team discovered that the type of surface oxygen species on platinum-based catalysts significantly affects hydrogen release from aqueous methanol. Contrary to prior beliefs, reactive lattice oxygen can hinder hydrogen formation by trapping intermediates, while platinum on hydroxyl-rich alumina showed the highest hydrogen production rate. This finding challenges existing assumptions and identifies a more effective catalyst design for hydrogen generation.
