Execution of compositional doping by more than one element simultaneously inside a carbon matrix is a challenging task for designing advanced carbon-based materials and nanotechnol. Herein, we have integrated a template-free methodol. for the preparation of a hollow sphere N,S co-doped carbon material utilizing melamine and p-toluenesulfonic acid as a nitrogen and sulfur precursor, highlighting a cost-effective, simple, and green process. This N,S dual doped carbon material acted as a promising bifunctional catalyst for sustainable CO2 fixation to form a cyclic carbonate with an epoxide, and this strategy is appealing for the conversion of CO2 to chems. The as-synthesized catalyst was comprehensively characterized by FESEM and HRTEM techniques, showing that the formed nanosheets arranged randomly in the shape of a sphere and turned out to be a hollow sphere after carbonization. The XPS anal. revealed that the randomly arranged nanosheets are linked via -C-S-S-C- linkages. The abundance of weakly acidic and basic sites helps to achieve very high activity (GC conversion 95% and selectivity 98%) in a CO2-epichlorohydrin cycloaddition reaction at 343 K temperature in the presence of a co-catalyst. The exptl. results coupled with the theor. adsorption energy calculation led us to propose that majorly the CO2 mol. gets adsorbed on the pyridinic N species while epichlorohydrin prefers a terminal -SO2H acidic site for adsorption. Addnl., the DFT study elucidated the detailed reaction mechanism for the CO2-epichlorohydrin reaction and identified the attack of CO2 by the iodoalkoxy anion as the rate-determining step. Beneficially, this study establishes a definitive relationship between CO2 utilization and an advanced heteroatom doped carbon-based catalyst.
