My current research topics include preparation and characterization of hydrogen separation membranes and hydrogen production catalysts. Among separation processes, membrane separation can be recognized as one of the most feasible energy-saving techniques without phase transformation, and furthermore, it makes possible continuous operation, process miniaturization and cheaper cost process. And, the idea of coupling catalytic reaction and membrane separation gives novel reaction environment because theare are so many merits caused by reaction product separation due to the Le Chatelier's law. The reason why this novel integrated reaction system is so attractive is that one-pass conversion and reaction selectivity will be improved compared with existing industrial reaction processes. Hydrogen-separating type reactors incorporated with hydrogen permselective membarne with thermal durability is now applied to a lot of hydrogen productions via the steam reforming of various hydrocarbons and alcholes, and via decomposition and dehydrogenation of hydrogen delivery and storage compounds.
