Scientists cut harmful pollution from hydrogen engines

Scientists have discovered a low-cost method to significantly reduce this pollution from hydrogen internal combustion engines by improving the efficiency of their catalytic converters. The researchers found that infusing platinum in catalytic converters with a highly porous material called Y zeolites greatly enhances the reactions between nitrogen oxides and hydrogen, converting unhealthful nitrogen oxides into harmless nitrogen gas and water vapor.
