    Abstract: Nanoparticle catalysts are manufactured by first preparing a solution of a solvent and a plurality of complexed and caged catalyst atoms. Each of the complexed and caged catalyst atoms has at least three organic ligands forming a cage around the catalyst atom. The complexed and caged catalyst atoms are reduced to form a plurality of nanoparticles. During formation of the nanoparticles, the organic ligands provide spacing between the catalyst atoms via steric hindrances and/or provide interactions with a support material. The spacing and interactions with the support material allow formation of small, stable, and uniform nanoparticles.

    Abstract: Carbon monoxide and carbonyl sulfide emissions are reduced in manufacturing processes, including titanium tetrachloride production processes. Gas is contacted with CO, COS, and an oxygen-containing gas with a suitable catalyst. The catalyst may be a metal oxide catalyst containing bismuth, cobalt and nickel, a xerogel or aerogel catalyst containing Au, Rh, Ru and Co in aluminum oxide/oxyhydroxide matrices, or a supported metal catalyst that contains at least one metal from the group Pd, Rh, Ru and Cu. In the latter case, the catalyst support is contains alumina or carbon. A catalyst composite of Au, Rh, Ru and Cr, and cerium oxide and lanthanum oxide may also be used.
