Sorption analysis of those materials was performed by collecting of N2 and CO2 isotherms. BET surface areas were calculated for the compositions containing higher proportions of Ti-MOF in the composite. CO2 isotherms also show that composites containing higher MOF loadings have higher gas uptake values. These values are higher than expected based on their molar proportion. Based on the isosteric heat of adsorption (ΔHads) values, it is observed that glass provides strong polar sites that demonstrated that with an increment on the Ti-MOF proportion in the composite, ΔHads values are similar to the pristine Ti-MOF.
