Co-pelletization of a zirconium-based metalorganic framework (UiO-66) with polymer nanofibers for improved useable capacity in hydrogen storage

Author: Bambalaza, Sonwabo E ; Langmi, HW ; Mokaya, R ; Musyoka, Nicholas M ; Khotseng, LE Date: Dec 2020 We report on a concept of co-pelletization using mechanically robust hydroxylated UiO-66 to develop a metal-organic framework (MOF) monolith that contains 5 wt% electrospun polymer nanofibers, and consists of an architecture with alternating ...

Experimental demonstration of dynamic temperature-dependent behavior of UiO-66 metal-organic framework: Compaction of hydroxylated and dehydroxylated forms of UiO-66 for high-pressure hydrogen storage

Author: Bambalaza, Sonwabo E ; Langmi, HW ; Mokaya, R ; Musyoka, Nicholas M ; Khotseng, LE Date: May 2020 High-pressure (700 MPa or ∼100 000 psi) compaction of dehydroxylated and hydroxylated UiO-66 for H2 storage applications is reported. The dehydroxylation reaction was found to occur between 150 and 300 °C. The H2 uptake capacity of powdered ... Read more
Incorporation of UiO-66 into graphene foam for hydrogen storage applications

Author: Bambalaza, Sonwabo E ; Langmi, Henrietta W ; Musyoka, Nicholas M ; Ren, Jianwei ; Khotseng, LE Date: May 2018 The fabrication of application-specific metal-organic framework (MOF) composites has the potential to shift more towards hydrogen storage system integration. The in-situ growth of nano particles on a graphene surface is a common technique for ... Read more
Simultaneous quantification of acetaminophen and tryptophan using a composite graphene foam/Zr-MOF film modified electrode

Author: Kemmegne-Mbouguen, JC ; Tchoumi, FP ; Mouafo-Tchinda, E ; Langmi, HW ; Bambalaza, Sonwabo E ; Musyoka, Nicholas M ; Kowenje, C ; Mokaya, R Date: Jul 2020 A graphene foam/zirconium-based metal–organic framework composite (GF/UiO-66) was synthesised and then employed to modify glassy carbon electrodes (GCE). These modified electrodes were successfully used for the simultaneous detection and ... Read more
