| Abstract: | Adsorption of water
vapour on a series of nickel-chromia samples has been studied. Nickel-chromia,
with 15% chromium is an active catalyst for H-D (hydrogen-deuterium) exchange
in hydrogen-water system, where water is in vapour phase. Water vapour
adsorption/desorption indicate that it is adsorbed on the catalyst both
physically and chemically. The 15% chromium catalyst sample has been treated
with phenylethyl triethoxy silane to make it hydrophobic and active in liquid
water-hydrogen system of H-D exchange. Water vapour adsorption isotherm on the
treated sample shows the hydrophobization of the catalyst. |
