2020年4月29日 · Flexible reduced graphene oxide (rGO) sheets are being considered for applications in portable electrical devices and flexible energy storage systems....

2020年5月27日 · The combination bridging of covalent and π–π bonding agents was demonstrated to efficiently increase the strength of reduced GO (called rGO) sheets to 1.05 GPa (refs. 16,17,18).

Reduced graphene oxide (rGO) consists of a few sheets of carbon that are usually derived from GO powders prepared by Hummers’ method and then reduced to lower the oxygen content. This reduction process can occur using chemicals such as hydrazine hydrate, strong acids (HNO 3 or H 2 SO 4 ), or heating [ 124 , 138 , 139 ].

2023年12月1日 · In this study, reduced graphene oxide nanosheets (rGO) were synthesized using a chemical bottom-up technique of modified Hummer’s method. The as-synthesized graphene sheets were characterized optically by Fourier Transform Infra Red spectroscopy (FTIR) and Raman spectroscopy.

2022年9月1日 · As a solution to these problems, we demonstrate a low-cost, chemical-free, fast (∼1 s), and low-temperature (∼140 °C) fabrication of 3D free-standing pure rGO aerogel structure using an electrical plasma-triggered reduction of a casted GO aerogel without destroying of its original 3D physical form.

2022年1月25日 · The anchored ultrafine nanoparticles could inhibit the wrinkling of the rGO nanosheet, forming highly stable colloidal solutions for the solution processing fabrication of nanofiltration...

A green and facile approach has been developed for the large-scale synthesis of nanosheets of reduced graphene oxide (rGO) and nitrogenated reduced graphene oxide (N-rGO). This has been achieved by direct thermal decomposition of sucrose and glycine ...
