Author:Gitari, MW; Petrik, LF; Musyoka, Nicholas MDate:Aug 2016South African coal combustion power utilities generate huge amounts of coal fly ash that can be beneficiated into zeolitic products. This chapter reports on the optimization of the presynthesis and synthesis conditions for a pure-phase zeolite ...Read more
Author:Sikhwivhilu, LM; Mpelane, S; Moloto, N; Ray, Suprakas SDate:Jan 2010The influence of the method of synthesis in the properties of the tubular structures derived from TiO2 was investigated using XRD, SEM and BET analysis. The use of microwave irradiation resulted in the formation of TiO2 tubes comprising anatase ...Read more
Author:Sikhwivhilu, LM; Ray, SS; Coville, NJDate:Mar 2009A hydrothermal treatment of titanium dioxide (TiO2) with various bases (i.e., LiOH, NaOH, KOH, and NH4OH) was used to prepare materials with unique morphologies, relatively small crystallite sizes, and large specific surface areas. The ...Read more
