Kinetic Regularities of Methane Dry Reforming Reaction on Nickel-Containing Modified Ceria–Zirconia

Energies, 2021
The Ni-containing catalysts based on ceria–zirconia doped with Ti and Ti+Nb were prepared by the solvothermal method in supercritical fluids. Ni deposition was carried out by incipient wetness impregnation and the one-pot technique.

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

Investigating the preparation of Cu3Mo2O9 as a photocatalyst

Catalysis Communications, 2022
The structural formation of copper molybdate was investigated using a surfactant added during the preparation. The calcined materials were confirmed by XRD to be Cu3Mo2O9 and the absorbance band-gap was calculated to be ca. 2 eV.

Hydrogenation of different carbon substrates into light hydrocarbons by ball milling

Nature Communications, 2023
The conversion of carbon-based solids, like non-recyclable plastics, biomass, and coal, into small molecules appears attractive from different points of view. However, the strong carbon–carbon bonds in these substances pose a severe obstacle, and thus—if
