General description

We are committed to bringing you Greener Alternative Products, which adhere to one of the four categories of Greener Alternatives. Chromium metal is used as a catalyst precursor in ethylene polymerization, enabling efficient production of high-performance polymers, offering a greener, potentially more sustainable option for advanced materials synthesis. Click here for more information.
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.
