General description

Chromium is widely used as a catalyst in chemical synthesis. It is also used in the preparation of other chromium-based compounds.

Application

Chromium (Cr) powder can be used in the preparation of Cr-based nanoporous metal-organic frameworks in activated carbon. This composite is used as an adsorbent for the removal of contaminants of emerging concern (CECs) from water.
