PENGARUH JENIS PCA PADA PROSES PEMBUATAN KATALIS Cu2O-ZnO/C TERHADAP PERSENTASE METANOL YANG DIHASILKAN DARI KONVERSI CO2 SECARA REDUKSI ELEKTROKIMIA
The electrochemical reduction process to produce methanol is carried out using Membrane Electrode Assembly (MEA) as the reaction center. The Cu2O-ZnO/C catalyst was used to make various electrodes with the addition of a process control agent (PCA). The characterization results using the Particle Size Analyzer (PSA) method found that the particle size of the catalyst using methanol PCA has a greater value than n-hexane PCA, with an average value of 53.82 μm while the particle size of the catalyst with n-hexane PCA is 50. 0743 μm. The results of the Brauner Emmet Teller (BET) analysis found that for n-hexane PCA, the pore diameter value was 154 A, the pore volume was 0.521 cm3/g and the surface area was 135.073 m2/g , while for the methanol PCA the pore diameter value was 0.199 A, pore volume value of 56.8 cm3/g and surface area value of 140.513 m2/g. Based on the results of ECSA calculations and the results of SEM-EDX analysis, the best electrodes were found in electrodes with PCA methanol with a Cu content of 70.028 Wt% with an ECSA value of 0.15 m2/g. Based on the results of EIS calculations, the best electrode is the electrode with an n-hexane PCA of 16.36 S/cm. Based on the measurement results, the highest methanol content was found in MEA with a methanol PCA of 16.2% in conditions of a stack size of 10 × 10 cm with an electrolysis time of 2 hours.
