چکیده
Diamond/graphene composite three-dimensional electrode has attracted extensive attention because of its low background current, wide potential window from diamond component, and high electrochemical activity graphite component. In this work, by using the hot wire chemical vapor deposition method, nano diamonds are embedded in vertical graphene sheet on surface single particle layer regulating short-term growth time to form a electrode. The results show that exhibits (3.59 V) very current (1.27 mA/cm<sup>2</sup>) when nano-diamond crystals grow top sheet. structure coated with is key broadening reducing current. With increase time, grows grains into lamellae, novel nano-diamond/graphene lamellae constructed. ordered increases active area 677.19 μC/cm<sup>2</sup> specific capacitance 627.34 μF/cm<sup>2</sup>. components makes narrow, effectively reduce This study provides new method for preparing nanodiamond/graphene electrodes deposition, idea fully exploiting synergistic effect diamond/graphene films.

Manganese dioxide nanofibers with length ranged from 0.1 to 1 μm and a diameter of about 4-6 nm were prepared by a chemical precipitation method. Composite electrodes for electrochemical supercapacitors were fabricated by impregnation of the manganese dioxide nanofibers and multiwalled carbon nanotubes (MWCNT) into porous Ni plaque current collectors. Obtained composite electrodes, containing 8...

From two-dimensional graphene oxide to three-dimensional honeycomb-like Ni3S2@graphene oxide composite: insight into structure and electrocatalytic properties
Three-dimensional (3D) graphene composites have drawn increasing attention in energy storage/conversion applications due to their unique structures and properties. Herein, we synthesized 3D honeycomb-like Ni3S2@graphene oxide composite (3D honeycomb-like Ni3S2@GO) by a one-pot hydrothermal method. We found that positive charges of Ni2+ and negative charges of NO3- in Ni(NO3)2 induced a transfor...
