要約(英語): Sulfonated carbon catalysts with sulfonic group (?SO3H), carboxyl group (-COOH), and hydroxyl group (-OH) were synthesized via a gas-liquid interfacial plasma (GLIP) sulfonation system with 1 mol/L H2SO4 at room temperature. However, the sulfonation process is not clearly understood. In the plasma process, gas-phase species such as SOX radicals are expected to play an important role in the sulfonation process. Consequently, optical emission spectroscopy (OES) and Fourier-transform infrared (FT-IR) spectrometry were used to investigate the gas-phase species in the sulfonation process. It was confirmed by FT-IR measurements that SO2 gas can be generated by plasma discharge with H2SO4 solution whereas could not be generated with Na2SO4 solution. In this research, we add carbon material in plasma discharge to confirm the importance of SO2 generation.
