AbstractA systematic study of Ni supported on metal-organic frameworks (MOFs) catalyst (i.e., 15Ni/UiO-66) for catalytic CO2 hydrogenation under nonthermal plasma (NTP) conditions was presented. The catalyst outperformed other catalysts based on conventional supports such as ZrO2, representing highest CO2 conversion and CH4 selectivity at about 85 and 99%, respectively. We found that the turnover frequency of the NTP catalysis system (1.8 +/- 0.02 s(-1)) has a nearly two-fold improvement compared with the thermal catalysis (1.0 +/- 0.06 s(-1)). After 20 hr test, XPS and HRTEM characterizations confirmed the stability of the 15Ni/UiO-66 catalyst in the NTP-activated catalysis. The activation barrier for the NTP-activated catalysis was calculated as similar to 32 kJ mol(-1), being lower than the activation energy of the thermal catalysis (similar to 70 kJ mol(-1)). In situ DRIFTS characterization confirmed the formation of multiple carbonates and formates on catalyst surface activated by NTP, surpassing the control catalysts (e.g., 15Ni/alpha-Al2O3 and 15Ni/ZrO2).
