A novel composite based on NiCo2O4@NG/MnOOH nanorods for high-performance supercapacitor electrodes

Synthesis of MnOOH and its application in a supporting hexagonal Pd/C catalyst for the oxygen reduction reaction

“…2.1 Synthetic process 2.1.1 Synthesis of MnO 2 . The chemical reagents used in this experiment were purchased from Shanghai Maclin Biochemical Technology Co., Ltd. To select MnO 2 with the best catalytic performance for oxygen reduction as a carrier, three types of MnO 2 were synthesized by the hydrothermal method, 38,39 labeled MnO 2 -1, MnO 2 -2, and MnO 2 -3, respectively. The dosage and synthesis route of the three MnO 2 synthetic raw materials are shown in Table 1 and Fig.…”

Recent advances in Ni-materials/carbon nanocomposites for supercapacitor electrodes

“…NiCo 2 O 4 holds promise for addressing energy storage challenges and plays a crucial role in advancing supercapacitor technology. The nanocomposite of graphene/NiCo 2 O 4 /MnOOH prepared by Yadav et al , 126 showed remarkable capacitive behavior for use in a novel coin cell supercapacitor device. NiCo 2 O 4 /ZnCo 2 O 4 /graphene/carbon nanotubes with significant electrochemical properties were combined with AC electrodes for preparing supercapacitors with good energy and power densities.…”

NiCo2O4@SnS2 nanosheets on carbon cloth as efficient bi-functional material for high performance supercapacitor and sensor applications

“…However, the semi conductive characteristic and restricted surface faradaic redox reactions of pristine NiCo 2 O 4 makes it challenging to meet commercial criteria. To overcome the aforementioned issues, a lot of research have directed on the synthesis of NiCo [13][14][15][16][17][18]. Although these materials exhibit good electrochemical performances but none of these are found to be having noteable bifunctional properties.…”
