CO2 conversion driven by the negative surface of phytoliths and alkali soluble ions released from phytoliths: (A) A schematic description regarding the co-presence of phytolith, its occluded OC and other soluble substances in solution; (B) a parallel reactor system designed to examine the effect of increasing CO2 concentration on: (C) CO2 sequestration and (D) change in the surface charge (zeta potential, ζ) of the suspensions prepared from phytoliths obtained from open burning and controlled heating in a temperature range from 250 to 950 °C.
