Researchers at the CAS DICP have developed a stainless steel reactor with a palladium composite membrane which allowed ammonia decomposition to hydrogen under long-term stable operation for 2000 h. Combination with an ammonia decomposing Ru/MgO catalyst in a membrane reactor reduced the temperature for complete ammonia decomposition from above 748 K to 673 K at stable operation for 200 h.
