Reaction can either be acid or base catalysed. Among the different base catalysed reactions MgO has attracted keen interest from researchers in the last two decades. For different types of reactions different base strength catalyst is required. The basic strength of MgO can be modified in different ways including alkali metal doping of MgO which is main aim of this work. Also the acidic and basic properties of which are measured under different atmospheres to demonstrate the impact of this variable. The Alkali doped MgO catalyst was prepared by impregnation method and the acidic and basic sites were determined using CO2 and NH3. It was found that doping of MgO with alkali metals significantly decreased the BET surface area and decreased the phase transition temperature for brucite to periclase by about 50°C. Alkali metal doping also significantly increased the number of basic sites whilst decreasing the number of acidic sites as compared to pure MgO. Under a hydrogen atmosphere the number of basic sites on alkali metal doped MgO significantly increased.
