Nickel Phosphide Catalysts as Efficient Systems for CO2 Upgrading via Dry Reforming of Methane

This work establishes the primordial role played by support’s nature when aimed at constitution of Ni2P active phases for supported catalysts. Thus, carbon dioxide reforming methane was studied over three novel catalysts on Al2O3, CeO2 and SiO2-Al2O3 oxides. The catalytic performance, shown catalysts’ series, decreased according to sequence: Ni2P/Al2O3 > Ni2P/CeO2 Ni2P/SiO2-Al2O3. depleted CO2 conversion rates discerned Ni2P/SiO2-Al2O3 sample were associated high sintering rates, large amounts coke deposits lower fractions constituted in catalyst surface. strong deactivation issues found catalyst, which also exhibited small species, majorly Ni oxidation issues. Along with surface areas, reactions might affect behaviour sample. With highest rate optimal stabilities, excellent performance depicted mostly related noticeable larger species established.
