The production of biogenic silica from different South African agricultural residues through a thermo-chemical treatment method

Maseko, Ncamisile Nondumiso; Schneider, Denise; Wassersleben, Susan; Enke, Dirk; Iwarere, Samuel Ayodele; Pocock, Jonathan; Stark, Annegret (MDPI, 2021-01-09)

A thermo-chemical treatment method was used to produce biogenic amorphous silica from South African sugarcane and maize residues. Different fractions of South African sugarcane (leaves, pith, and fiber) were processed ...
Synthesis of low density and high purity silica xerogels from South African sugarcane leaves without the usage of a surfactant

Nondumiso Maseko, Ncamisile; Enke, Dirk; Iwarere, Samuel Ayodele; Oluwafemi, Oluwatobi Samuel; Pocock, Jonathan (MDPI, 2023-03-05)

Sugarcane leaves were used to produce high-purity and low-density silica xerogels through a sol–gel method. The biogenic silica produced through a thermochemical method was reacted with sodium hydroxide (NaOH) to form ...
