Ammonia (NH3)-Related Catalysts by TANAKA Precious Metals


Ammonia (NH3) is expected to have potential as a hydrogen carrier as well as a zero-emission fuel that, similar to hydrogen, does not emit carbon dioxide during combustion. We provide ammonia reforming catalysts that decomposes ammonia to generate hydrogen as well as catalysts for suppressing and decomposing nitrogen oxides (NOx) and nitrous oxide (N2O) in exhaust gas containing ammonia.
