Shape selective plate-form Ga(2)O(3) with strong metal-support interaction to overlying Pd for hydrogenation of CO(2) to CH(3)OH.

A stronger metal-support interaction between Pd and plate-form Ga(2)O(3) nanocrystals covered with the predominant 002 surface than other Ga(2)O(3) surfaces is found, which gives higher methanol yield in catalytic CO(2) hydrogenation.
