1. George Hasegawa, Shizuka Moriya, Miki Inada, Masaaki Kitano, Masaaki Okunaka, Takahisa Yamamoto, Yuko Matsukawa, Kazuma Nishimi, Kazunari Shima, Naoya Enomoto, Satoru Matsuishi, Hideo Hosono, Katsuro Hayashi, Topotactic Synthesis of Mesoporous 12CaO 7Al2O3 Mesocrystalline Microcubes toward Catalytic Ammonia Synthesis, Chemistry of Materials, 30, 4498-4502, 2018.07, Topotactic conversion route from the hydrogarnet precursor provides mesoporous 12CaO·7Al2O3 (C12A7) mesocrystalline microcubes with high surface area. Mechanism for the cubic morphology with a single-crystal nature and the mesopore formation has been investigated in detail. The Ru-loaded mesoporous C12A7 microcubes deliver a fairly high potential as a heterogeneous catalyst for ammonia synthesis under ambient pressure..
