Carbon Formation during Methane Dry Reforming over Ni-Containing Ceria-Zirconia Catalysts
Nanomaterials, 2022 Two series of Ni/Ce(Ti/Nb)ZrO2 catalysts were prepared using citrate route and original solvothermal continuous flow synthesis in supercritical isopropanol and studied in dry reforming of methane (DRM). TEM, XPS and FTIRS of adsorbed CO confirm influence
