a Stability tests in RWGS reaction at 600 °C over IM-Cu/TiO2, SP-Cu/TiO2, and SP-Cu/LaTiO2 samples. b–d ADF-STEM images and particle size distributions of b SP-Cu/LaTiO2-500R, c SP-Cu/LaTiO2-100h, and d SP-Cu/LaTiO2-500h catalysts. e Comparison of the RWGS reaction path over three models from DFT calculations. f Long-term thermal stability of SP-Cu/LaTiO2 at 800 °C. Inset was the TEM image and the distribution of Cu nanoparticles of the used catalyst.
