Insights into durable NiCo catalysts on β-SiC/CeZrO2 and γ-Al2O3/CeZrO2 advanced supports prepared from facile methods for CH4-CO2 dry reforming

- CeZrO2 with γ-Al2O3 or SiC were prepared by impregnation and deposition precipitation.
- CeZrO2 with γ-Al2O3 or β-SiC as dual supports promote particle dispersion for NiCo.
- The catalysts enable stable reforming reaction without any deactivation for 550 h.
- Undiluted 60/40 feed ratio of CH4/CO2 does not induce coking during 78 h of reaction.
- Coking as low as 0.6 wt.% was obtained, due to high oxygen mobility from ceria.
