Adsorption kinetics of halloysite nanotube and modified halloysite at the Palm oil-water interface and Pickering emulsion stabilized by halloysite nanotube and modified halloysite nanotube

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2019
Abstract In this study, the interfacial tension behavior of halloysite nanotube (HNT) as a hydrophilic nanoparticle and modified APTES-HNT as a hydrophobic nanoparticle at the palm oil-water interface was investigated. The result of this study was used to determine the stability and potential formation of Pickering emulsion as a novel dispersed ...

Nanohybrid silver nanoparticles@halloysite nanotubes coated with polyphosphazene for effectively enhancing the fire safety of epoxy resin

, 2020
In an attempt to develop an efficient flame retardant for epoxy resin (EP), a hierarchical “dots-core–shell” structure Ag@HNT@PZE was prepared via simple two-step reactions including in-situ growth of Ag within halloysite nanotubes (HNT) and a ...

Structure of prismatic halloysite

American Mineralogist, 2013
The crystal structure of halloysite, despite being one of the most commonly occurring clay minerals on the Earth’s surface, remains elusive. This paper reports on a multi-methodological study to shed more light on the atomic arrangement of halloysite from Olkhon Island, Lake Baikal, Russia, which has a prismatic morphology.

Improved NO x Reduction in the Presence of SO2 by Using Fe2O3-Promoted Halloysite-Supported CeO2-WO3 Catalysts.

Environmental Science and Technology, 2019
Currently, selective catalytic reduction (SCR) of NO x with NH3 in the presence of SO2 by using vanadium-free catalysts is still an important issue for the removal of NO x for stationary sources.

Halloysite in Deltaic Alluvium

Transactions of the Indian Ceramic Society, 1986
Among the clay minerals present in the deltaic alluvium of Manmathanagar soil (West Bengal), the presence of halloysite has been detected in the fifth horizon with the help of transmission electron microscopy. This seems to be the first report on halloysite in deltaic alluvium.

Geopolymerization of halloysite via alkali-activation: Dependence of microstructures on precalcination

, 2020
Halloysite has a chemical composition very similar to that of kaolinite, but it possesses a special nanotubular structure and surface reactivity. This work focuses on the geopolymerization of halloysite via alkali-activation, and investigates the effects
