Why does the Conductivity of a Nickel Catalyst Increase during Sulfidation? An Exemplary Study Using an In Operando Sensor Device

open access: yesSensors, 2015
In order to study the sulfidation of a catalyst fixed bed, an in operando single pellet sensor was designed. A catalyst pellet from the fixed bed was electrically contacted and its electrical response was correlated with the catalyst behavior.

Direct quantification of hydrophobicity: a case study of environmentally relevant silver nanoparticles

open access: yesFrontiers in Nanotechnology, 2023
Among the physical and chemical properties of nanomaterials, hydrophobicity is considered to play a key role in their impact on the environment. Changes in hydrophobicity resulting from abiotic and biotic processes can be used to predict the behaviours ...

Sulfidation of NiCo-Layered Double Hydroxide and its Capacitance performance

open access: yesInternational Journal of Electrochemical Science, 2020
Nickel-cobalt layered double hydroxide (NC-LDH) and Na2S were used as precursors and sulfur source, synthesizing a series of sulfurized products at different degrees by hydrothermal method. The structure of products was characterized by X-ray diffraction.
