The role of methoxide species in selective formation of iso butene from CO and H 2 over ZrO 2 was investigated by means of 13 C tracer method. Analysis of 13 C 13 C coupling in the formed iso butene showed that 12 CO hydrogenation over ZrO 2 pretr

The adsorbed species on ZrO2 and CeO2 during CO hydrogenation forming branched carbon chains, especially isobutene, (over ZrO2), have been investigated by chemical trapping, in situ IR, and solid-state NMR methods. These indicated that methoxide and

The CO hydrogenation mechanism of selective isobutene formation over ZrO2 and CeO2 catalysts was investigated. The chemical trapping and 13C tracer studies showed that branched chain is formed by the carbonylation of C1 species produced from C-O bond

The CO–H2 reaction over ZrO2 was carried out in the presence of various organic additives. The addition of dimethyl ether, methylal, acetaldehyde, and dimethyl acetal showed the marked enhancement effects on the hydrocarbon formation keeping the hi

The dependency of water-isoluble and slightly soluble dyes on the composition of nonionic hydrocarbon-anionic hydrocarbon and of nonionic hydrocarbon-amionic fluorocarbon surfactants in micelles has been studied through the solubilization characteris
