CO2 reduction over noble metal/carbon nanotube catalyst
… technique, show good catalytic activity for CO2 reduction in the contexts of dry reforming (DR) of methane (CH_4 + CO_2 -> 2CO + 2H_2) and reverse water gas shift (RWGS) (H2 + CO_2 -> CO + H_2O). Reaction temperatures range from 773 to 973 K, with system pressure at 30 psig. The feed molar …

Electrochemical CO2 reduction on Cucurbit[n]uril modified Gold
… from slow reaction kinetics, low solubility of CO2 and hydrogen formation as a competing side reaction. In general, rational control over reaction intermediates via (de-)stabilising interactions remains a major challenge in electrocatalysis more broadly. In this thesis, gold surfaces were …
