Abstract: The present invention provides porous composition, such as those monoliths with tortuous flow through channels from aggregates comprising small particles. The present invention also relates to methods of making these solid networks and the use of these networks for a variety of functions. The nanoporous solid can be formed into a wide variety of macroscopic shapes and sizes and can be used as chromatographic supports, supports for solid phase chemistry, high surface area packing for chemical reactors, and separation, mixing, or reaction matrix for microfluidics devices. The method of making these networks comprises high shearing of the particles via, for example, a homogenizer, in an incompatible fluid so that the particles form a continuous open network. The method also comprises cross-linking the particles together via a linker species to “lock-in” the open network structure formed during shearing.

Abstract: This invention relates to novel cobalt and molybdenum promoted titania and nickel and molybdenum promoted titania catalysts, and molybdenum promoted titania catalysts containing mixtures of cobalt and nickel. The invention also relates to a process for using the catalysts to convert sulfur in the form of carbon sulfides and nitrogen present as hydrogen cyanide to hydrogen sulfide and ammonia respectively. The catalysts and process of the present invention are effective even when oxygen in concentrations up to about 2 volume %, preferably 1.0 volume %, (dry basis) is present. The catalyst comprises about 0.5 to about 5%, by weight, cobalt oxide (CoO), nickel oxide (NiO), or mixtures thereof; about 1.5 to about 15%, by weight, molybdenum trioxide (MoO.sub.3); and about 70 to about 98%, by weight, titanium dioxide (TiO.sub.2).
