By means of DAC, herein a facile method has been developed to capture CO2 with a designed system of biomass cellulose-added Ca2+ solution. The resultant calcite CaCO3 is found to be uniformly attached to the cellulose fibrils. Compared to a non-cellulose system, cellulose raises the CO2 capture efficiency by 32%.
