SEM analyses revealed a well-developed microporous structure, while EDX confirmed its elemental composition.

XRD analysis confirmed the amorphous nature of the material, and pH_PZC and zeta potential measurements clarified the surface charge characteristics. Batch experiments, supported by kinetic and isotherm modeling, showed that methylene blue (MB) adsorption onto AC-PPSC_1–1 follows pseudo-second-order kinetics and fits the Freundlich isotherm, indicating multilayer physisorption.

As thermodynamic equilibrium analysis offers key insights into species stability, reactant conversion, and product selectivity, a thermodynamic equilibrium study of the RWGS reaction, CO₂ methanation, CO₂ hydrogenation to methanol, ethanol and ethylene glycol was conducted using Aspen Plus V12.1 simulation software, with the Peng-Robinson equation of state as the thermodynamic model.
