Belonging to the investigations which have thus far been conducted concerning the absorption of co2 by metallic oxides, much is closely linked to the thermal decomposition with carbonates and has been studied in order to throw light on such type of reaction1-6. The two approaches include much in common and endure the same kind involving experimental and theoretical negatives. For instance, each won't proceed independently of other; false equilibria can end up being obtained from either side of equilibrium plus the counter-pressure effect in energy decomposition is analogous on the ratelimiting diffusion of carbon dioxide in the absorption problem. Studies7’8 involving the healing of zinc oxide surfaces with water vapour and carbon dioxide have shown that water will be the preferentially adsorbed species but in these cases very little evidence was

 found of a bulk phase reaction. In the recent publication9 the fun roles of water vapour

 and carbon dioxide while in the bulk phase formation of zinc hydroxycarbonate happen to be discussed and it was found that once the reaction conditions were optimised, zinc oxide might be completely converted to zinc hydroxycarbonate as outlined by the equation.
