Abstract Chromic potassium sulphate is found to be an efficient and recyclable catalyst for the selective oxidation of thiols to disulfides.
The reaction was carried out in 60% methanol (v/v) using 30% H2O2 at room temperature. Cr(III) forms a complex with thiol which was then oxidized by H2O2 to produce disulfide in excellent yield after a simple workup procedure.

Abstract The present research work involves the nature of interaction between the Ru(II) complex and inorganic peroxides in the absence
of excitation by light photons. We synthesized a photosensitizer, ([Ru(dcbpy)2(biq)]Cl2·3H2O) and studied its thermal degradation in the presence of inorganic peroxides (hydrogen peroxide, peroxomonosulfate and peroxodisulfate).
Progress of the thermal reaction between the Ru(II) complex and each peroxide in 0.5 M H+ solutions was followed spectrophotometrically by monitoring the disappearance of the Ru(II) complex at its maximum absorbance
(λ = 514 nm). The reactivities of the peroxides were compared and suitable mechanisms proposed.

Abstract Two kinds of Cu/SiO2 catalysts were prepared by impregnation (IM) and ion-exchange (IE) methods, and tested in dehydrogenation of 2-butanol to
methyl-ethyl-ketone. Some kinds of Cu2+ on the IE catalyst could not be reduced during the reaction, and it produced the butene. The copper oxide over the IM catalyst
could be reduced during the reaction, and showed stable dehydrogenation activity for 2-butanol.

Abstract Alkylation of 2-naphthol with tripropylene in the presence of zeolite catalysts HBEA, H-Y and H-MFI was studied. Comparative
studies on the catalytic properties of H-BEA, H-Y and H-MFI zeolites were carried out under identical reaction conditions.
The results showed that the H-BEA catalyst exhibited outstanding catalytic performance; and the conversion and selectivity
of 2-naphthol could be 52.1% and 86.3%, respectively. It was found that the structure and acid strength of zeolite catalysts
were the major influencing factors for the conversion and selectivity of 2-naphthol alkylation.

Abstract Selective catalytic reduction of nitrogen monoxide (NO) over a catalyst of mechanically mixed Nb/TiO2 and Mn2O3 (Mn2O3+Nb/TiO2) in an oxidizing atmosphere with propene (C3H6) was studied. The Mn2O3+Nb/TiO2 catalyst showed high activity for the reduction of NO to N2. The maximum conversion of NO to N2 was observed at 200∼300°C, with about 80% reduction of NO to N2. Mn2O3 enhanced the formation of NO2 from NO and the activation of propene to react with NO2 for reduction to N2.

Abstract New chiral Co-salen complexes with tert-butyl group in position 5 of the aromatic ring in the structure have been synthesized and they were applied as a chiral catalyst.
A dimeric chiral salen having a transition metal salt such as AlCl3, displayed very high catalytic reactivity and enantioselectivity for the asymmetric ring opening of epoxides to synthesize
optically pure α-aryloxy alcohols via phenolic kinetic resolution.

Abstract Rhodium and cerium were found to be suitable additives for improving the sulfur-tolerance of Ni-based gasoline reforming catalysts.
In these cases, the Rh content was only 0.1 wt.% with 5 wt.% of Ce. The lifetime of Rh-Ce-modified Ni-based catalyst is found
to be above 600 hours at 1023K, which is over a ten times longer lifetime than that of the unmodified catalysts, when premium
gasoline was used.

Abstract Solid acid supports such as H-ZSM5, H-Mordenite, γ-Al2O3, USY and Beta catalysts were modified with Pt. These Pt/oxide catalysts were found to be active for propane formation through
aqueous reforming of glycerol in the presence of hydrogen. The reforming reactions, possibly, proceeded through reaction cycles
of dehydration on acid sites and hydrogenation on Pt sites over the catalysts.

Abstract Vanadium-containing H6+xP2Mo18−xVxO62 (x = 0, 1, 2 and 3) Wells-Dawson heteropolyacid (HPA) and H3+xPMo12−xVxO40 (x = 0, 1, 2 and 3) Keggin HPA catalysts were applied to the vapor-phase dehydrogenation of cyclohexanol. The catalytic oxidation
activity showed a volcano-shaped curve with respect to vanadium substitution for both families of HPA catalysts. The Wells-Dawson
HPA showed a better catalytic oxidation performance than the Keggin HPA at the same level of vanadium substitution.

Abstract This work evaluated the effects of pH on decolorization of C.I. Reactive Red 2 by O3, O3/Fe(II), UV/O3 and UV/O3/Fe(II) systems. At pH 4, the decolorization rate constants of O3, O3/Fe(II), UV/O3 and UV/O3/Fe(II) systems were 1.78, 3.11, 2.04 and 3.18 hr−1, respectively. The decolorization rates and effective energy consumption constants of all systems were higher under basic
conditions than under acidic conditions.

Abstract The oxidation of low concentration formaldehyde in air over Au/CeO2, prepared by co-precipitation, was investigated. Power-law kinetic models were proposed and the parameters were estimated,
which are r = −0.46 × e−14612 / RTCHCHO(303 K < T < 363 K) and r = −295.78 × e−34178 / RTCHCHO (363 K < T < 413 K). The mechanism of the reaction at low temperatures might be different from that at high temperatures.

Abstract A series of hexaaluminates, La0.8A0.2MnAl11O19−δ samples (A = Ba, Ca, Sr and Y) as new catalysts were prepared by carbonate precipitation and calcined at high temperature.
The structure and properties of these samples were characterized by XRD, BET and XPS techniques. Upon calcination at 1200°C,
the hexaaluminate structure was formed and it retained the specific surface area of 17∼20 m2g−1. The La0.8Ca0.2MnAl11O19−δ catalyst has a surface area of 19.3 m2g−1 and shows a good activity in CH4 combustion.

Abstract The high-throughput technique has been successfully employed to investigate systematically NH3 decomposition catalysts for COx-free hydrogen production. Supported γ-Mo2N catalysts not only could be prepared and evaluated by the high-throughput experiment, but are also active for NH3 decomposition luke supported Ni and Co catalysts. Additionally, the preparation process and support play important roles
on the catalytic performance of supported γ-Mo2N catalysts.
