Title : Photoactive Anisotropic Plasmonic Metal-Semiconductor Nanohybrids For Improved Solar-Fuel Conversion Systems


A novel electrode of NiCo2O4 nanowire arrays (NWAs) on new carbon material which takes advantage of the high electrical conductivity to boost the pseudocapacitive performance. Graphene or carbon nanotubes based thin films have been used to fabricate flexible solid-state supercapacitors with high gravimetric specific capacitances (80–200 F/g), but usually with a rather low overall or areal specific capacitance (3–50 mF/cm2) due to the ultra-small electrode thickness (typically a few micrometers) and ultralow mass loading, which is not desirable for practical applications. So we report that Edible Lentinula edodes will give more specific capacitance when compared to other carbon electrodes. NiCo2O4 mesoporous arrays together with the synergistic effect between NiCo2O4 and e-C will result in a high specific capacitance. Here we expect, with a e-C having high surface area combining with NiCo2O4 could enhance the specific capacitance, low leakage current, excellent cycling stability, and extraordinary mechanical flexibility.
