Description

General description

Chromium (III) oxide is a chromium complex in which the chromium ion is in +3 oxidation state. The synthesis of its sub-micron powder has been reported.† The IR and Raman spectra of chromium (III) oxide have been studied.† The impact of adding lysozyme on the stability of chromium (III) oxide (Cr₂O₃) suspension has been evaluated.†

Application

Chromium (III) oxide may be used in the following processes:

• To modify carbon paste electrodes for optimizing its ability to detect nitric oxide.
• Preparation of Ni+Cr₂O₃ composite coatings.
• Formation of the ternary oxide, CrVMoO₇ by solid-state reaction which may be employed in selective oxidation reactions.

Used in a solid-state reaction to form the new ternary oxide, CrVMoO₇, can be used in selective oxidation.
