One of the key methods for CO2 fixation in the applied chemical and industrial sectors is the conversion of CO2 into cyclic carbonates, which is significant from the standpoint of green chemistry and reaching net zero emissions. In this context, a series of novel boron-doped nanotube TiO2 compounds (B1-ntTiO2 and B16-ntTiO2) have been synthesized as the catalysts for the synthesis of cyclic organic carbonates via CO2 insertion various epoxides under suitable conditions. The characteristic properties of the catalysts were examined by XRD, FT-IR spectra TEM and SEM. Subsequently, under suitable conditions (1.6 MPa, 100 °C, 2 h), novel boron-doped nanotube TiO2 compounds were tested for the coupling reaction of CO2 with various epoxides to obtain target cyclic carbonates for carbon neutrality and as a substitute for toxic reagents like phosgene. There was an attractive increase in efficiency with the use of boron-doped catalyst, and 96 % efficiency and 99.2 % selectivity were achieved with the B16-ntTiO2 catalyst. Reusability tests exhibited that the efficiency of the catalyst decreased to 80 % on the third cycle, the selectivity was found to be around 99 %.
