Acylation of anisole with benzoyl chloride over rapidly synthesized fly ash–based hbea zeolite
Ameh, Alechine E.; Musyoka, Nicholas M.; Oyekola, Oluwaseun (Frontiers Media, 2021)Stable HBEA zeolite with high surface area and strong acid sites was synthesized from coal fly ash–based silica extract via indirect hydrothermal synthesis. The rapid HBEA hydrothermal crystallization times of 8, 10, and ... -
Compaction of a zirconium metal–organic framework (UiO-66) for high density hydrogen storage applications
Bambalaza, Sonwabo E.; Langmi, Henrietta W.; Mokaya, Robert; Musyoka, Nicholas M.; Renad, Jianwei; Khotseng, Lindiwe E. (Royal Society of Chemistry, 2018)We report a rare case whereby a metal–organic framework (MOF), namely UiO-66, is compacted at high pressure ( 700 MPa or 100 000 psi) resulting in densification and improved total volumetric hydrogen storage capacity, ... -
Synthesis of zeolites from coal fly ash using mine waters
Musyoka, Nicholas M.; Petrik, Leslie; Fatoba, Ojo O.; Hums, Eric (Elsevier, 2013)In this study mine waters obtained from coal mining operations in South Africa were used as a substitute for pure water during the synthesis of zeolites from South African coal fly ash. Procedures that had been optimized ... -
Transformation of fly ash based nanosilica extract to BEA zeolite and its durability in hot liquid
Ameh, Alechine E.; Fatoba, O. O.; Musyoka, Nicholas M. (Elsevier, 2020)Power generation in South Africa relies heavily on the combustion of coal and during this process, coal fly ash (CFA) is generated as by-product, which raises several environmental issues. The transformation of CFA into a ...
