Questioning the catalytic effect of Ni nanoparticles on CO2 hydration and the very need of such catalysis for CO2 capture by mineralization from aqueous solution

© 2017 Elsevier Ltd Recent publications claimed a significant catalytic effect of nickel nanoparticles on the hydration of CO 2 to carbonic acid. Others have claimed that such catalysis can significantly accelerate the overall process of CO 2 capture by mineralization to CaCO 3 from aqueous solution...
