Currently, large-scale production of graphene is achievable through the reduction of graphene oxide (GO) either by chemical or thermal methods [16], [19]. Unfortunately, due to incomplete reduction or numerous structural defects, the quality of the produced graphene is far inferior compared to ...
In this work, we have successfully prepared sandwich-like structured N-doped porous carbon@graphene composites (N-PC@G) derived from sandwich-like structured zeolitic imidazolate framework@graphene oxide (ZIF-8@GO). ZIF-8@GO was obtained by in situ controllable growth of ZIF-8 nanocrystals on ...
A simple and effective preparation method for the simultaneous reduction and functionalization of graphene oxide (rGO) by 2,4-diamino benzene sulfonic acid has been developed. The derivatives exhibit excellent conductivity and high dispersibility in various solvents. The successful preparation of rGO and...

Modulated electron conductivity (EC), p-n junction behavior and light-harvesting semiconductivity in reduced graphene oxide (rGO) is observed. Pristine graphene oxide (GO) film on borosilicate glass was reduced by ascorbic acid (AA), Glucose (GC), hydrogen iodide (HI), thiourea (TU), ...
The introduction of graphene into the fiber structure greatly increases the electrical conductivity and specific surface area of the material. At the same time, Fe--N4 structure helps to form an effective catalytic center of ORR. Compared with Pt/C, it has similar catalytic activity in alkaline ...
In this work, we utilize a one-step pyrolysis method to thermally synthesize phosphorus (P), sulfur (S) and nitrogen (N) ternary-doped graphene (PSNG) using graphene oxide (GO), phosphoric acid and thiourea precursors as a low-cost and highly-efficient catalyst for the oxygen reduction ...
CO and CH4. Of particular interest is that they have high selectivity for CO. It’s worth noting that the porous CNs also possess outstanding photocatalytic oxidation ability on high concentration nitric oxide (NO), and the highest NO conversion rate can reach 79.3% under visible light. The en...
S and N co-doped graphene frameworks have been successfully prepared by the hydrothermal treatment of ammonium thiocyanate and graphene oxide. By consideration of the abundant of heteroatom-containing organic precursors to be applied, this work offers a one-pot, low-temperature, inexpensive and scalabl...
