Gallium palladide explained

Gallium palladide (GaPd or PdGa)^[1] is an intermetallic combination of gallium and palladium. It has the iron monosilicide crystal structure.^[2] The compound has been suggested as an improved catalyst for hydrogenation reactions.^{[3] [4]} In principle, gallium palladide can be a more selective catalyst since unlike substituted compounds, the palladium atoms are spaced out in a regular crystal structure rather than randomly.^{[5] [6]}
