The groups of Yoshiaki NISHIBAYASHI at the University of Tokyo and of Kazunari YOSHIZAWA of Kyushu University have jointly developed a molybdenum PCP type pincer complex which produced ammonia catalytically by reacting atmospheric nitrogen gas with a reducing agent and a proton source at room temperature. The molybdenum nitrogen catalyst showed catalytic activity even after completion of the reaction for 20 hours. One molecule of this catalyst was able to synthesize up to 230 molecules of ammonia from nitrogen gas.
