Monometallic nano-catalysts for the reduction of perchlorate in water

摘要

Perchlorate removal in a clean, cost-effective and publicly acceptable approach is one of the important issues in current drinking water treatment practice. Catalytic membrane (CM) was prepared by coating monometallic catalysts of the nano-size onto supports by chemical or electrochemical method. The support materials were stainless steel and graphite. Nano-catalysts were made of transitional metals from the first, the second and the third row of the periodic table. The CM was characterized by surface analysis techniques including SEM, XPS and BET.
