Enhanced thermoelectric properties exhibited by unreduced freestanding graphene oxide/carbon nanotube membranes

Abstract

Herein we determine the Seebeck coefficients, electric conductivities, and thermoelectric power factors of a range of unreduced graphene oxide (GO)/single-wall carbon nanotube (CNT) membranes incorporating different GO/CNT ratios as well...

An efficient oxygen evolution reaction catalyst using Ni–Co layered double hydroxide anchored on reduced graphene oxide

“…20 The disappearance of the (001) peak and the emergence of a new diffraction peak at 2y = 241 in the XRD pattern of rGO demonstrates that graphite oxide has been well reduced. 20 The NiCo-LDH sample exhibits five characteristic diffraction peaks at 2y values of 11.11, 22.11, 34.41, 38.61, and 60.71, which can be indexed to the (003), ( 006), (009), ( 015) and (110) planes of hydrotalcite-like LDH phase in good agreement with previous reports. 21,22 The XRD pattern of the NiCo-LDH@rGO catalyst retains the corresponding peaks of pure NiCo-LDH, revealing the existence of NiCo-LDH in the composite without affecting the crystalline phase of LDH.…”

The role of graphene in new thermoelectric materials

“…Incorporating graphene into thermoelectric materials can improve their mechanical properties, including hardness, flexibility, and tensile strength. 63,66,67 This enhancement can make the materials more durable and reliable for various thermoelectric applications, although the optimal graphene content and distribution need to be carefully managed.…”

Enhanced mixed proton and electron conductor at room temperature from chemically modified single-wall carbon nanotubes

“…During past decades, single-wall carbon nanotubes (SWCNT) are widely studied 1D carbon allotropes in different areas of application due to their unique physical and chemical properties. 15,16 The SWCNTs are extremely mechanically stable and exible. Hexagonal networks of CNTs consist of shells of carbon atoms that are sp 2 -hybridized.…”
