Research Activity
He has published over 540 papers in scientific journals in addition to review articles and book chapters.
1. Tailoring of corrosion-resistant alloys
1-1 Tailoring of corrosion-resistant amorphous and nanocrystalline alloys by melt spinning,
sputter deposition,
mold casting and powder consolidation
1-2 Passivity of corrosion-resistant alloys
1-3 Role of corrosion-resistant elements such as chromium, molybdenum, tungsten, valve metals, etc.
1-4 Tailoring of extremely corrosion-resistant bulk amorphous alloy
1-5 Tailoring of corrosion-resistant alloys in sulfidizing and oxidizing environments at high temperatures
2. Tailoring of electrocatalytically active and corrosion-resistant materials for electrolysis of
aqueous solutions
2-1 Tailoring of chlorine evolution electrodes for electrolysis of seawater
2-2 Tailoring of amorphous alloy electrocatalysts for fuel cells
3. Key materials and systems for global CO2 recycling - For supply of abundant energy and
for prevention of global warming-
3-1 Tailoring of oxygen evolution anodes for seawater electrolysis
3-2 Tailoring of hydrogen production cathodes for seawater electrolysis
3-3 Seawater electrolysis system for hydrogen production and oxygen evolution
3-4 Tailoring of catalysts for carbon dioxide methanation
3-5 Carbon dioxide methanation system
In particular, he has built a prototype plant for global CO2 recycling in 1995 on the roof top of the Institute for Materials Research, Tohoku University. The plant consists of power generation by solar cell on a desert, hydrogen production by seawater electrolysis and methane formation by the reaction of carbon dioxide with hydrogen at a desert coast, carbon dioxide recovery at an energy consuming district, and transportation of carbon dioxide to the desert coast. The plant uses tailored key materials with high performance and durability, that is, cathodes for hydrogen production, anodes for only oxygen evolution without chlorine evolution in seawater electrolysis, and catalysts for rapid and selective production of methane by the reaction of carbon dioxide with hydrogen. The performance of the plant has substantiated that global CO2 recycling can supply abundant energy generated from solar energy on deserts in the form of methane and can really prevent global warming induced by carbon dioxide emissions. In 2003, he has built a pilot plant of global CO2 recycling at Tohoku Institute of Technology which is the minimum unit of industrial scale for seawater electrolysis and carbon dioxide methanation.
