The catalytic activity of nickel in the form of aerosol and aerogel

Porous Materials for Applications in Energy and Environment

“…In 1930 Gibbs and Liand first reported obtaining a nickel aerogel from nickel carbide, applying an electric arc and under the hydrogen gas flow; they reported that this nickel aerogel weakly catalyzed the reduction of carbon-to-methane monoxide, despite its huge specific surface area [57]. A year later, Kistler first prepared a silica aerogel with a very small density value of 0.02 g/cm 3 , as he also was the first who prepared alumina gels, nickel tartarate, tin oxide, tungsten oxide, nitrocellulose, cellulose, gelatin, agar, and egg albumin [58].…”

Physicochemical Properties of Carbon Materials: A Brief Overview

“…Despite this comparison, many researchers may have the impression that these are relatively recent concepts. However, the Web of Science (isiwebofknowledge.com) quickly reveals, for example, that aerogel catalysts were compared to the more conventional aerosol counterparts in the 1930s [19]. The origin of the term aerogel is straightforward: The solvent is replaced by gas (air), thus maintaining the low density of the final product.…”

Heterogeneous catalysis

“…He suggests that one might expect the most unsaturated points to be less active catalytically, for the adsorbate would be more firmly bound to a highly unsaturated atom. Gibbs and Liander (33) have recently reported an attempt to verify Taylor's theory experimentally. A material prepared in a colloidal condition would be expected to furnish an excellent catalyst.…”
