CO2 is a critical reaction for achieving carbon neutrality. Low-temperature operation (below 250 degrees C) is important to promote selective CH4 production. In this study, we focused on Ru/m-ZrO2 catalysts, examining how the catalyst preparation method influenced the CO2 methanation. Interestingly, Ru/m-ZrO2 catalysts prepared via a selective deposition method exhibited remarkably high activity, achieving a CO2 conversion of 82% and CH4 selectivity of >99% at 250 degrees C. This exceptional low-temperature performance can be attributed to the robust interaction between Ru and ZrO2, which enhanced the activation of CO2. The catalytic performance remained unchanged for 70 h.
