Hydrogenation is a reductionreactionwhich results in an addition ofhydrogen(usually as H2). If anorganiccompoundis hydrogenated, it becomes more "saturated" with hydrogen atoms. The process typically requires the use of a catalyst, since hydrogenation only occurs spontaneously at high temperatures. The...
