Introduction	Achieving carbon-neutral hydrogen generation is crucial for the future chemical industry. This study introduces a novel thermal catalytic method for the partial reforming of ethanol, yielding hydrogen and acetic acid with virtually no carbon dioxide emissions. The process utilises a catalyst featuring a high concentration of atomic platinum (Pt) and iridium (Ir) species, supported on a reactive alpha-molybdenum carbide substrate. This system achieves a hydrogen production rate of 331.3 millimoles per gram catalyst per hour and an acetic acid selectivity of 84.5% at 270°C, offering improved energy efficiency over conventional reforming techniques. A techno-economic assessment of partial ethanol reforming indicates strong potential for profitable industrial-scale operation, providing a pathway for hydrogen and acetic acid output with a significantly lower carbon footprint.
