Low-Temperature CO<sub>2</sub> Methanation over Ru Nanoparticles Supported on Monoclinic Zirconia
CO2 is a critical reaction for achieving carbon neutrality.
Low-temperature operation (below 250 °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 °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
