The inside of a catalyticconverteris hot, steamy, and filled with oxygen. This might sound nice, but it's actually aharsh environmentthat deactivates precious metal catalysts. As soon as someone drives a car, the nanoparticles of catalyst present in the catalytic converter are exposed to high ...
Making the precious metal the catalytic converter null substrate for exhaust airPURPOSE: To enhance an active temp. range of a catalyst and to improve heat resistance by using a crystalline silicate having mesopores as a carrier and depositing a part of a noble metal inside the mesopores. ...
If you own a vehicle, there’s a strong chance you own a small amount of palladium because the metal is likely present in your catalytic converter, its most common application. However, it’s not the only use of the metal. Palladium is used in medical applications like blood sugar test s...
With first process, first metal (M1= transition metal; For example, Co, Cr and Ru), it is activated by rising reaction temperature to the 80 - the 160 . In second process, the second metal (the M2= precious metal; For example, Pt, Pd, Au and those blends) is added, and, slurry...
Inside converse micelle to the production mannered null precious metal and the porous body of the catalytic converterPROBLEM TO BE SOLVED: To provide a catalyst excellent in life by preventing coagulation of noble metal particles .中村 雅紀
