Author:Wang, K; Kang, X; Ren, Jianwei; Wang, PDate:Nov 2016In this study, nanostructured graphite (nano-G) was added to LiBH(sub4) and examined with respect to its effect on the hydrogen storage properties of the system. Our study found that nano-G is an effective additive for promoting the reversible ...Read more
Author:Ren, Jianwei; Segakweng, T; Langmi, Henrietta W; North, Brian C; Mathe, Mahlanyane KDate:Oct 2015Metal–organic framework (MOF) materials are only obtained as loose powders with low packing density and thermal conductivity. To enable the developed MOF powdered materials to be utilized in a hydrogen storage system, in this study, MIL-101 ...Read more
Author:Musyoka, Nicholas M; Mutuma, BK; Manyala, NDate:Jul 2020High surface area activated carbons (ACs) were prepared from a hydrochar derived from waste onion peels. The resulting ACs had a unique graphene-like nanosheet morphology. The presence of N (0.7%) and O content (8.1%) in the OPAC-800 °C was ...Read more
Author:Ren, Jianwei; Langmi, Henrietta W; North, Brian C; Mathe, Mahlanyane KDate:Sep 2014Development of safe and effective hydrogen storage systems is critical for further implementation of hydrogen in fuel cell technologies. Amongst the various approaches to improve the performance of such systems, porous materials-based adsorptive ...Read more
Author:Musyoka, Nicholas M; Swartbooi, Ashton M; Langmi, Henrietta W; North, Brian CDate:Oct 2013Hydrogen storage has been a key bottle-neck in the actualization of hydrogen as an energy carrier. The new field of hydrogen storage in templated carbonaceous materials has excited many researchers and considerable effort is being directed ...Read more
Author:Wang, K; Kang, X; Zhong, Y; Hu, C; Ren, Jianwei; Wang, PDate:Nov 2014Nanoconfinement has been widely employed as a promising strategy to improve dehydrogenation kinetics, reversibility, and equilibrium pressure of complex metal hydrides. In this paper, we report a careful study of the influence of nanoconfinement ...Read more
