Answer
Aldehydes can be prepared by the hydrogenation of acid chloride, in the presence of palladium supported by Barium sulphate. This reaction is called Rosenmund reduction.
In the above reaction, $BaSO _4$ act as a catalytic poison to palladium catalyst, so that aldehyde cannot be further reduced to alcohol.
