Abstract: 
The water dissociation ability of Ca‐doped MgO is significantly enhanced compared to pure MgO, based on a decrease in the kinetic barrier of the water dissociation step due to electronic and steric (size) effects. This allows for a complete conversion of an Mg0.9Ca0.1O phase within 80 min to the corresponding mixed hydroxide.
