Single and multiwalled carbon nanotubes (SWCNT & MWCNT) have been investigated over the past three decades because of their excellent properties, including their mechanical strength and large electrical and thermal conductivities. Incorporating CNTs into consumer and industrial products is challenging because of strong attractive interactions, heterogeneity, and lack of separation techniques for these nanomaterials. Further challenges include those associated with CNT interaction and adsorption to interfaces. In the present work, the properties of an air/water interface laden with industrial grade MWCNTs with systematically varied oxidative treatment in nitric acid were measured. The duration of treatment was varied and the surface …

Manganese oxide (MnOx) and multiwalled carbon nanotubes (MWCNTs) are intended to modify the GC electrode for oxygen evolution reaction (OER). Optimization of MnOx loading is carried out and the deposition of 55 cycles was sufficient to obtain the highest activity toward OER. The stability of the catalyst is enhanced by the addition of MWCNTs. As a result, an amount of 22 kWh/Kg of O2 of energy is saved. Several techniques including cyclic voltammetry, linear sweep voltammetry, chronoamperometry, chronopotentiometry, field-emission scanning electron microscopy, and energy dispersive X-ray spectroscopy will be combined to track the catalyst activity and to determine its morphology …
