Enhancing the performance of Cu catalysts for the reverse water–gas shift reaction using N-doped CNT–ZnO composite as support

Abstract

The Reverse Water-Gas Shift reaction (RWGS) allows the conversion of CO2 to syngas, a mixture of H2 and CO, used to manufacture most chemicals and synthetic fuels. Consequently, it is...

Double-Edged Sword Effect of Classical Strong Metal–Support Interaction in Catalysts for CO2 Hydrogenation to CO, Methane, and Methanol

“…Recently, Querido et al 99 used N-doped carbon nanotubes (CNT)-ZnO composite as support for Cu NPs. Under the same RWGS reaction conditions, the obtained sample achieved a high CO yield of ∼49% for 93 h at 600 °C under 0.1 MPa and a WHSV of 60 L g −1 h −1 , whereas the pristine Cu/CNT only reached a low CO yield of 17.6%.…”

Stabilized inverse Y2O3/Cu interfaces boost the performance of the reverse water–gas shift reaction

“…1–4 In this case, Cu-based supported catalysts have emerged with great potential for the large-scale application of the RWGS reaction owing to their high CO selectivity and low cost. 5–8 Generally, the Cu-oxide interfaces in conventional supported catalysts play a crucial role in the RWGS reaction. 5–11 However, active Cu species prefer to agglomerate at high temperatures, resulting in the serious loss of Cu-oxide interfaces and decreasing the catalytic activity and stability.…”

“…5–8 Generally, the Cu-oxide interfaces in conventional supported catalysts play a crucial role in the RWGS reaction. 5–11 However, active Cu species prefer to agglomerate at high temperatures, resulting in the serious loss of Cu-oxide interfaces and decreasing the catalytic activity and stability. 5–11 Therefore, the construction of stable Cu-based supported catalysts with abundant interfaces is still a challenging task to realize the industrialization of the RWGS reaction.…”
