New Publication – Cr3+ role in CuCrO2 Synthesis

In our latest work by Amanda Chown published in Inorganic Chemistry, we show that Cr³⁺ acts as a reductant in the hydrothermal synthesis of CuCrO₂ from Cu²⁺ precursors. This synthesis is widely used in the literature to generate CuCrO₂ nanocrystals, however, the exact role of Cr³⁺ as a reductant had never been identified. The information leads to a new stoichiometric ratio of 4:3 Cr:Cu needed to produce pure CuCrO₂. Deviations from this can result in side product impurities.
