Synthesis and electrochemical properties of hollow-porous MnO 2 -graphene micro-nano spheres for supercapacitor applications

Powder Technology, 2014
Abstract Hollow-porous MnO 2 -graphene (GR) micro-nano spheres for supercapacitors were synthesized via a simple, quick and cost-effective strategy at room temperature. The crystal structure and morphology of the as-prepared materials were investigated by X-ray diffraction (XRD), field emission scanning electron microscope (FESEM) and nitrogen ...

Folded nano-porous graphene-like carbon nitride with significantly improved visible-light photocatalytic activity for dye degradation

Ceramics International, 2017
Abstract Graphitic carbon nitride (g-C 3 N 4 ) prepared by traditional methods has various disadvantages, e.g., small specific surface area, low band gap, high photo-generated carriers recombination and low exfoliation efficiency, which limits its practical application.

Engineered architecture of nitrogenous graphene encapsulating porous carbon with nano-channel reactors enhancing the PEM fuel cell performance

Nano Energy, 2017
Abstract Nanoscale architecturing of platinum group metal-free (PGM-free) electrocatalysts is expected to dramatically improve the overall catalytic performance for oxygen reduction reaction (ORR). Desired structures and morphologies for boosting active site density and enhancing mass and charge transfer are essential for developing next-generation ...
