Various transition metal oxides were placed in a eutectic mixture of sodium hydroxide and potassium hydroxide at 250°C and the products were analyzed with Raman spectroscopy. Many compounds did not appear to be Raman active. Raman peak shifts for vanadium(V) oxide and chromium(VI) oxide were observed post-reaction, providing strong evidence for the successful reduction in oxidation state. Exposing the vanadium(Y) oxide to elevated temperatures yielded nearly identical spectra. The results suggest that chromium(VI) oxide was reduced to chromium(III) oxide and vanadium(V) oxide was reduced to vanadium(IV) oxide. Further analysis is encouraged to confirm the identity of the other products, particularly those that changed color and did not yield discernable Raman peaks.
