A new bicarbonate-based microalgae cultivation system coupled with an electrochemical CO<sub>2</sub>absorption process to improve carbon utilization efficiency.
Magnesium phyllosilicate (Mg–APTES) was developed and explored for its applicability as a potent carbonation catalyst that converts CO2 into carbonate ions. Careful investigation of its surface properties revealed a lamellar structure and the existence of an amine group, which is the expected CO2 capture site. The prepared magnesium phyllosilicate was found to successfully convert gaseous CO2 into HCO3− (bicarbonate ion), actively forming CaCO3 (calcium carbonate) when Ca2+ (calcium ion) was sup
CO2 mineralization sequestrates CO2 in a form of mineral carbonate through chemical reactions of CO2 with metal oxide or alkaline solution. This process is attractive because it has no risk for a leakage of hazardous materials and requires a relatively small area for sequestrating CO2 compared to geological storage. In addition, generated mineral carbonate can be used as useful chemicals if its purity is high enough. One of the recent ideas in CO2 mineralization is integrating it with desalinati
The ever-increasing air pollution has brought the treatment of nitrogen oxides (NOX) to the forefront of flue gas purification. Wet absorption achieves outstanding NOX removal efficiency, but it suffers from an oxidative deactivation of the NOX absorbent, iron(II) thiochelate, by the residual O2 in flue gases. To address this critical issue, we demonstrate a regeneration process to electrochemically reduce the oxidized iron thiochelate into the original form to effectively bind nitric oxide (NO)
