Journal ArticleDOI
Magnesium–carbon hydrogen storage hybrid materials produced by reactive ball milling in hydrogen
Mykhaylo Lototskyy,J.M. Sibanyoni,Roman V. Denys,M. Williams,Bruno G. Pollet,Volodymyr A. Yartys +5 more
TL;DR: In this article, the authors uncovered the kinetics and mechanism of Mg-hydrogen interactions during high energy reactive ball milling in hydrogen (HRBM) in presence of various types of carbon, including graphite (G), activated carbon (AC), multi-wall carbon nanotubes (MWCNT), expandable (EG) and thermallyexpanded (TEG) graphite.
Journal ArticleDOI
Investigation of hydrogen storage capacity of multi-walled carbon nanotubes deposited with Pd or V
Yindee Suttisawat,Pramoch Rangsunvigit,Boonyarach Kitiyanan,M. Williams,Patrick Ndungu,Mykhaylo Lototskyy,Alexander Nechaev,Vladimir Linkov,Santi Kulprathipanja +8 more
TL;DR: In this paper, the synthesis and characterization of multi-walled carbon nanotubes (CNTs) with Pd or V and their hydrogen storage capacity measured by Sievert's volumetric apparatus were presented.
Journal ArticleDOI
Chemical surface modification for the improvement of the hydrogenation kinetics and poisoning resistance of TiFe
M. Williams,M.V. Lototsky,Moegamat Wafeeq Davids,Vladimir Linkov,Volodymyr A. Yartys,Jan Ketil Solberg +5 more
TL;DR: In this paper, surface modification of the sintered Ti1.1Fe0.9Ox and arc-melted TiFe was performed using autocatalytic deposition of the Pd-based catalytic layers in order to achieve improvement of the H storage characteristics.
Journal ArticleDOI
Surface modification of TiFe hydrogen storage alloy by metal-organic chemical vapour deposition of palladium
Moegamat Wafeeq Davids,Mykhaylo Lototskyy,Alexander Nechaev,Q Naidoo,M. Williams,Yevgeniy Klochko +5 more
TL;DR: In this paper, the surface modification of a TiFe alloy was performed using a metal-organic chemical vapour deposition technique (MOCVD), by the thermal decomposition of palladium (II) acetylacetonate (Pd[acac]2) mixed with the powder of the parent alloy.
Journal ArticleDOI
Surface-modified advanced hydrogen storage alloys for hydrogen separation and purification
TL;DR: In this paper, the authors summarise collaborative activities of South African and Norwegian groups in the development and characterisation of advanced hydride-forming materials obtained by surface modification of AB5-type substrate by fluorination and/or electroless deposition of single or mixed-metal coatings on the basis of palladium.
