Synthesis of reversible carbon dioxide absorber based on hydrated zirconium oxide, intended for concentration and removal of CO2 in habitable closed objects

Abstract

Carbon dioxide absorber based on hydrated zirconium oxide was synthesized with ammonium carbonate and hydrogen peroxide. The effect of the molar ratio between ammonium carbonate and hydrogen peroxide on the sorption characteristics of the absorber was examined. The structural-sorption properties of the absorber were analyzed. It was shown tat the absorber has a high absorption capacity for CO₂.
