Synthesis of todorokite.
Golden DC, Chen CC, Dixon JB. Golden DC, et al. Science. 1986 Feb 14;231(4739):717-9. doi: 10.1126/science.231.4739.717. Science. 1986. PMID: 17800797
The infrared spectra and x-ray diffraction patterns were similar to those of natural todorokite samples. Calcium birnessite and nickel birnessite, when autoclaved under conditions similar to those for magnesium birnessite, yielded a todorokite structure. However, th …

Synthesis and Aerobic Oxidation Catalysis of Mesoporous Todorokite-Type Manganese Oxide Nanoparticles by Crystallization of Precursors.
Koutani M, Hayashi E, Kamata K, Hara M. Koutani M, et al. J Am Chem Soc. 2022 Aug 10;144(31):14090-14100. doi: 10.1021/jacs.2c02308. Epub 2022 Jul 20. J Am Chem Soc. 2022. PMID: 35860845
The pursuit of a high surface area while maintaining high catalytic performance remains a challenge due to a trade-off relationship between these two features in some cases. In this study, mesoporous todorokite-type manganese oxide (OMS-1) nanoparticles with high specific …
