a Apparent activation energies (Ea) and b reaction orders respective to H2 (\(n_{{\rm{H}}_2}\)) for methanol synthesis and the RWGS reaction over In2O3 catalysts as a function of their nickel content. c Graphical representation of the structures of In2O3 and Ni-In2O3 catalysts with low and high nickel loadings and indications where products shall be predominantly formed on them. The rings surrounding the molecules represent the respective product selectivity. Reaction conditions: T = 553 K, P = 5 MPa, WHSV = 24,000 cmSTP3 h−1 gcat−1.
