An i.r. study of carbon monoxide fixation by Ni+ ions obtained by photoreduction of a nickel-exchanged silica

Abstract

It is shown by i.r. spectroscopy, using mixtures of ¹²CO and ¹³CO, that isolated Ni⁺ ions produced by u.v. irradiation in hydrogen at 77 K of an Ni-exchanged silica can form mono- or di-carbonyl adducts in the 10^–5–5 Torr range.
