Catalytic Reduction of Dinitrogen to Ammonia by Use of Molybdenum–Nitride Complexes Bearing a Tridentate Triphosphine as Catalysts
Kazuya Arashiba,Eriko Kinoshita,Shogo Kuriyama,Aya Eizawa,Kazunari Nakajima,Hiromasa Tanaka,Kazunari Yoshizawa,Kazunari Yoshizawa,Yoshiaki Nishibayashi +8 more
TL;DR: Newly designed and prepared molybdenum-nitride complexes bearing a mer-tridentate triphosphine as a ligand have been found to work as the most effective catalysts toward the catalytic reduction of dinitrogen to ammonia under ambient conditions.
Journal ArticleDOI
Catalytic formation of ammonia from molecular dinitrogen by use of dinitrogen-bridged dimolybdenum-dinitrogen complexes bearing PNP-pincer ligands: remarkable effect of substituent at PNP-pincer ligand.
Shogo Kuriyama,Kazuya Arashiba,Kazunari Nakajima,Hiromasa Tanaka,Nobuaki Kamaru,Kazunari Yoshizawa,Kazunari Yoshizawa,Yoshiaki Nishibayashi +7 more
TL;DR: Time profiles for the catalytic reactions indicate that the rates of the formation of ammonia and molecular dihydrogen depend on the nature of the substituent on the PNP-pincer ligand of the complexes, which is complementary in the reaction system.
Journal ArticleDOI
Direct Transformation of Molecular Dinitrogen into Ammonia Catalyzed by Cobalt Dinitrogen Complexes Bearing Anionic PNP Pincer Ligands
Shogo Kuriyama,Kazuya Arashiba,Hiromasa Tanaka,Hiromasa Tanaka,Yuki Matsuo,Yuki Matsuo,Kazunari Nakajima,Kazunari Yoshizawa,Kazunari Yoshizawa,Yoshiaki Nishibayashi +9 more
TL;DR: The direct formation of ammonia from molecular dinitrogen under mild reaction conditions was achieved by using new cobalt dinitrogens complexes bearing an anionic PNP-type pincer ligand.
Journal ArticleDOI
Catalytic Reduction of Molecular Dinitrogen to Ammonia and Hydrazine Using Vanadium Complexes
Yoshiya Sekiguchi,Kazuya Arashiba,Hiromasa Tanaka,Aya Eizawa,Kazunari Nakajima,Kazunari Yoshizawa,Yoshiaki Nishibayashi +6 more
TL;DR: This is the first successful example of vanadium-catalyzed dinitrogen reduction under mild reaction conditions.
Journal ArticleDOI
Synergic Catalysis of PdCu Alloy Nanoparticles within a Macroreticular Basic Resin for Hydrogen Production from Formic Acid
Kohsuke Mori,Kohsuke Mori,Hiromasa Tanaka,Masahiro Dojo,Kazunari Yoshizawa,Kazunari Yoshizawa,Hiromi Yamashita,Hiromi Yamashita +7 more
TL;DR: The present catalytic system is particularly desirable for an ideal hydrogen vector in terms of potential industrial application for fuel cells and is cost-effective because of the superior catalytic activity compared with that of well-established precious PdAg or PdAu catalysts.
