Coordination Environment of Copper Sites in Cu-CHA Zeolite

 · Cu-CHA combines high activity for the selective catalytic reduction (SCR) reaction with better hydrothermal stability and selectivity compared to other copper-substituted zeolites. At the same time Cu-CHA offers an opportunity for unraveling the coordination environment of the copper centers since the zeolite framework is very simple with only one crystallographically independent tetrahedral

What is Copper Corrosion Definition from Corrosionpedia

 · Copper is considered to be a noble metal and as a result is able to resist attack by oxygen.The metal is basically immune to corrosion due to a naturally occurring protective film known as a patina that forms on the metal s surface. If this protective film usually consisting of reddish-brown cuprous oxide (Cu 2 O) is destroyed then copper will eventually corrode.
