Question

The ________ readily adsorbs hydrogen at room temperature.

Answer 1

Adsorption of Hydrogen:

• Palladium, platinum, or nickel readily adsorbs hydrogen at room temperature on their surface.
• In the case of both catalytic and surface chemistry, in understanding the chemical process the adsorption of hydrogen on transition metals like platinum and palladium plays an important role.
• Hydrogen adsorbed on palladium, also called occluded hydrogen, is absorbed on its surface by the formation of hydride.
• Palladium is also used in the hydrogen separation and purification process.
• Hydrogen atoms produce favorable adsorption energies on the surface of both platinum and palladium.
• When more than one hydrogen atom interacts with the metal surface simultaneously, they produce a repulsive effect on one another, causing the adsorption energy to be slightly lower on Palladium.

Hence, The Palladium, Platinum or Nickel readily adsorbs hydrogen on their surface at room temperature.
