In situ study of Co₃O₄ morphology in the CO-PROX reaction
The preferential oxidation (PROX) reaction is an effective process for the removal of trace amounts of carbon monoxide from a reformate stream. Tricobalt tetraoxide (Co₃O₄) is the candidate for CO-PROX in a H₂ rich gas and could be an alternative to the rare and expensive PGMs. This study …

Preferential oxidation of carbon monoxide in hydrogen-rich gases over supported cobalt oxide catalysts
The preferential oxidation of CO (CO-PROX) has been identified as one route of further reducing the trace amounts of CO (approx. 0.5 - 1 vol%) in the H2-rich reformate gas after the high- and low-temperature water-gas shift reactions. CO-PROX makes use of air to preferentially oxidise CO to CO₂, …

Supported Cobalt Oxide Catalysts for the Preferential Oxidation of Carbon Monoxide: An in situ Investigation
… in this thesis has placed great focus on Co3O4-based catalysts for producing CO-free H2-rich gas streams for power generation using proton-exchange or polymer electrolyte membrane fuel cells (PEMFCs). The removal of CO (0.5 – 2%) is essential as it negatively affects the performance of the …

Study of the effects of promoters (MnOx and FeOx) on Co3O4/CeO2 during Preferential Oxidation of Carbon monoxide
… there is an urgent need for improving access to eco-friendly and reliable energy alternatives. One of the leading and promising pollution-free high-energy carriers is hydrogen for fuel cells. Currently, hydrogen gas is mostly produced via steam reforming followed by the water-gas shift reaction …
