I am a chemistry masters student, currently researching CO2 conversion to fuels and chemicals, I am looking in particular at iron oxide nanoparticles to be used as a catalyst in the Reverse Water Gas Shift reaction, this requires the catalyst to be in the form of a solid, not in aqueous phase. As most nanoparticles are synthesised in aqueous solution, would the morphology and structure of the nanoparticles be impacted by removing them from the solution. The synthesis method being considered is co-precipitation.
