The present study combines nonthermal plasma (NTP) and thermal catalysis to exploit the synergism for direct conversion of CO2 to CH3OH using H2. Series of catalyst, that is, CuO/QW, NiO/QW, Fe2O3/QW, NiO/Fe2O3/QW, CuO/Fe2O3/QW have been tested for CO2 conversion and CH3OH selectivity. And it was observed that 5 wt% CuO/Fe2O3/QW exhibited better CO2 conversion and CH3OH selectivity as compared to other catalysts. With 5 wt% CuO/Fe2O3/QW, at 200°C and 2‐W NTP input power (100 ml/min feed flow and 1:3 ratio of CO2 and H2) about 16.7% CO2 conversion and 32.7% CH3OH selectivity have been reached. Indeed, the highest of 9.32 mmol h−1 gcat−1 of CH3OH space‐time yield is obtained over CuO/Fe2O3/QW, which is about two times higher than the reported value in the literature (4.41 mmol h−1 gcat−1 of CH3OH using Cu/ZnO/Al2O3, 30°C, feed flow 40 ml/min, and 30‐W input power).

使用Ni和Cu负载的Fe催化系统由CO2合成甲醇:了解非热等离子体表面放电的作用

本研究结合了非热等离子体(NTP)和热催化,以利用增效作用将H 2将CO 2直接转化为CH 3 OH 。测试了一系列催化剂,即CuO / QW,NiO / QW,Fe 2 O 3 / QW,NiO / Fe 2 O 3 / QW,CuO / Fe 2 O 3 / QW的CO 2转化率和CH 3 OH选择性。并且观察到,与其他催化剂相比,5wt%的CuO / Fe 2 O 3 / QW表现出更好的CO 2转化率和CH 3 OH选择性。含5 wt%的CuO / Fe 2O 3 / QW,在200°C和2W NTP输入功率(100 ml / min进料流量和1:2的CO 2和H 2比率)下,大约有16.7%的CO 2转化率和32.7%的CH 3 OH选择性到达。实际上,在CuO / Fe 2 O 3 / QW上获得的CH 3 OH时空产率最高,为9.32 mmol h -1  gcat -1,比文献报道的值(4.41 mmol h)高约2倍。CH 3 OH -1  gcat -1(使用Cu / ZnO / Al 2 O 3),30°C,进料流量40 ml / min和30W输入功率)。
