Controlled Growth of 3D Interpenetrated Networks by NiCoO and Graphdiyne for High-Performance Supercapacitor.

In this paper, the 2D all-carbon graphdiyne, which possesses superior 2D strength and high mixed conductivities for both electrons and ions, is used to protect nickel cobalt oxide nanostructures with multidimensions. The in situ grown graphdiyne seamlessly wraps on nanostructures to form 3D interpenetrating networks, leading to significant improvement in the conductivity and avoidance of the structural degradation. The assembled hybrid asymmetric supercapacitor showed a high specific capacitance of 200.

Facile synthesis of BiMoO/reduced graphene oxide composites as anode materials towards enhanced lithium storage performance.

BiMoO/reduced graphene oxide (BiMoO/rGO) composites were fabricated by a facile one-pot hydrothermal approach, in which BiMoO nanosheets and rGO were simultaneously obtained. The structure and composition of the as-synthesized BiMoO and BiMoO/rGO materials were characterized via FT-IR, BET, TGA, XRD, TEM, SEM and XPS analyses, and the electrochemical performance of BiMoO/rGO as an anode in a lithium-ion battery was investigated. Compared with pristine BiMoO, the BiMoO/rGO composites have higher capacities, better cycle stability and higher rates.

Facile synthesis of graphitic CN nanoporous-tube with high enhancement of visible-light photocatalytic activity.

A simple and convenient method was used to synthesize a graphitic carbon nitride (g-CN) nanoporous-tube by using SiO nanoparticles as pore formers. The structure of the g-CN nanoporous-tube was characterized by the SEM and TEM images. Taking photodegradation of RhB as an example, the photocatalytic activity of the as-prepared g-CN nanoporous-tube was investigated.

Enhanced visible light photocatalytic hydrogen evolution over porphyrin hybridized graphitic carbon nitride.

Tetra (4-carboxyphenyl) porphyrin (TCPP) was loaded on the surface of Pt/g-CN via a simple adsorption process, and the microstructure and chemical structure of the composites were characterized by high resolution transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, UV-visible diffused reflectance spectroscopy and photoluminescence spectroscopy. Loading TCPP onto Pt/g-CN enhanced the visible-light-driven photocatalytic evolution of H from water. The TCPP/Pt/g-CN composite with a TCPP loading of 1wt% had the highest photoactivity, which was 2.
