Studies of Carbon Dioxide Methanation and Related Phenomena in Porous Catalysts
This Dissertation investigates the kinetics of CO2 methanation over nickel and cobalt catalysts. Methanation was studied for both Ni/γ-Al2O3 and Co/ZrO2 catalysts, which were synthesised using an incipient wetness impregnation technique and subsequently characterised using analyses based on gas …

CO2 capture and utilization using dual-functional catalysts
The excessive atmospheric CO2 emission is one of the main contributions to the global climate change. However, with the growth of global economics, more fossil fuels will be consumed to feed the global activity, especially in developing countries. Thus, carbon capture storage and utilization draws …

Metal oxide supported iron-nickel nano-alloys in the reverse water-gas shift reaction
Rising atmospheric CO2 concentrations pose an existential threat to human life. The development of carbon capture and utilization (CCU) technologies which can consume CO2 at the same scale that it's being produced are necessary to limit the global mean surface temperature increase to 2 °C, in …

Supported Cobalt Oxide Catalysts for the Preferential Oxidation of Carbon Monoxide: An in situ Investigation
… the preferential oxidation of CO (CO-PrOx) to CO2 is a very attractive catalytic process for decreasing the CO content to acceptable levels (i.e.,< 10 ppm) for operating the PEMFC. Co3O4-based catalysts have shown very good catalytic activity for the total oxidation of CO in the absence of H2, …

Non-Thermal Contribution to Ruthenium Photothermal Catalyst in Carbon Dioxide Methanation
… in energy consumption and the release of CO2 into the atmosphere. Photothermal catalysis offers a promising strategy for sustainable chemical transformations by combining thermal and photonic energy to accelerate reactions under mild conditions to convert greenhouses into energy sources. …
