Low-temperature, atmospheric pressure reverse water-gas shift reaction in dielectric barrier plasma discharge, with outlook to use in relevant industrial processes

Plasma-Catalytic CO2 Hydrogenation over a Pd/ZnO Catalyst: In Situ Probing of Gas-Phase and Surface Reactions

“…Due to this, the energy efficiency for CO production also received a boost when using Pd/ZnO. In this study, the energy efficiency for CO production (up to 0.13 mmol kJ –1 , Figure c) was greater than those published in previous works under similar conditions. , …”

“…In this study, the energy efficiency for CO production (up to 0.13 mmol kJ –1 , Figure 1 c) was greater than those published in previous works under similar conditions. 36 , 37 …”

“…In this study, the energy efficiency for CO production (up to 0.13 mmol kJ −1 , Figure 1c) was greater than those published in previous works under similar conditions. 35,36 Figure 1 shows a plasma-catalytic synergy for both CO 2 conversion and CO yield, as well as the significance of Pd in the plasma hydrogenation of CO 2 over the Pd/ZnO catalyst. The plasma-catalytic synergy (CO 2 conversion and CO yield) over the 2 wt % Pd/ZnO catalyst was also confirmed when changing the gas flow rate (40−120 mL/min) and discharge power (10−20 W), as shown in Figure S6.…”

Advanced catalytic CO2 hydrogenation on Ni/ZrO2 with light induced oxygen vacancy formation in photothermal conditions at medium-low temperatures

“…However, in the PTC process, CO selectivity increased when the temperature was higher than 400 °C and reached 7.4% at 500 °C. Here, CO as a byproduct was probably from the reverse water gas shift reaction (CO 2 + H 2 → CO + H 2 O), which requires high temperature and low pressure in the absence of light, 34 but interestingly, the assistance of light may facilitate this reaction (even though under atmospheric pressure). In the control experiment, neither CH 4 nor CO was detected in the pristine ZrO 2 .…”

Plasma assisted CO2 splitting to carbon and oxygen: A concept review analysis

“…The topic of CO2 conversion and utilization is among those with the largest research interest in the recent years, with over 250 reviews in the last three years centred on various aspects, from thermochemical catalytic approaches (the various Power-to-X technologies [1,2], or catalytic/biocatalytic routes to produce valuable chemicals and monomers [3][4][5][6]) to photo and electro-catalytic approaches [7][8][9][10][11][12][13] and plasma-catalysis [14][15][16][17][18][19]. Notwithstanding this very large research interest, there are extremely few results in literature on what can be considered a dream reaction to reduce CO2 emissions, the carbon dioxide splitting (also called cracking, dissociation or decomposition, eq.…”
