“…In fact, K. M. Racik et al have synthesize MnO 2 /NiO nanocomposites via a facile hydrothermal method and have confirm the presence of both materials with two strong bands at 448 and 599 cm À1. 29 In addition, Das M., et al have obtained the same result of FTIR spectra. 56 The FT-IR spectrum of the trijunction sample showed different characteristic peaks of ZnO, NiO, and MnO 2 , which further confirmed the formation of the MnO 2 /NiO/ZnO NWs trijunction.…”

“…In fact, the preparation of MnO 2 /NiO nanocomposites via hydrothermal method exhibit a specific capacitance of 247 F g −1 at discharge current density rate of 0.5 A g −1. 29 Whereas the ZnO@MnO 2 hybrid material on flexible carbon cloth (CC) electrode displays a specific capacitance of 351.5 mF cm −2. 30 Several authors in the literature also study the combination of MnO 2 with graphene oxide materials to enhance the electrochemical performance of composite electrode 31,32 .…”

“…The bending vibrations of O‐H coupled with the Mn atoms are allocated to the absorption bands about 1627 and 1036 cm 1. 40 Inter‐atomic vibrations produce absorption bands below 800 cm 1 in metal oxides such as Ni‐O, Co‐O, and Mn‐O. The features of the Co‐O stretching vibrations in Co 3 O 4 are shown by the unique band at 576 cm 1 41 …”

“… 31 The weak band at approximately 1625 cm –1 for the cathode and anode films was assigned to the bending vibration of the O–H groups with metal atoms. 32 The peaks at approximately 1140 and 921 cm –1 were attributed to the bending vibration of -OH groups combined with metal atoms and could be due to O–H stretching vibrations. 33 , 34 The broad peak at approximately 1114–1178 cm –1 (centered at 1140 cm –1 ) for the anode suggested disordered structures or hydrogen bonding interactions.…”
