Low laser power micro-Raman study of Co(1−x)Mn(x)Fe2O4 prepared by flash combustion method

Exfoliated graphite with spinel oxide as an effective hybrid electrocatalyst for water splitting

“…For pure MnCo 2 O 4 particles, only one characteristic peak at 680 cm −1 corresponding to the stretching vibration mode of M–O (M = Mn, Co) was determined. 32,33 Also, in hybrid samples the peak for M–O is visible. However, the sample is not entirely homogeneous and in some places, a lack of response from M–O vibrations can be observed (see Fig.…”
