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