一般描述

Chromium(III) oxide (Cr2O3) is an inorganic compound with wide applications in construction materials, heterogeneous catalysis, enamels, green pigments, plastic, and paints. These listed applications are due to its unique properties like high oxidative resistance and melting temperature. Furthermore, a permanent green coloring in cement is achieved by Cr2O3.

应用

Chromium(III) oxide can be used:
  • To dope TiO2 nanocrystallites photoanodes applicable in dye-sensitized solar cells.
  • As a bulk mediator in the modification of carbon paste electrodes applicable in nitric oxide sensing.
用于形成新型三元氧化物 CrVMoO7 的固态反应,此三元氧化物可用于选择性氧化。
