LZ and SLZ catalysts are fairly active for oxidative coupling of methane. Their catalytic performance can be further improved by adding K+ cations (supposedly in the form of K2O) as promoters. Under conventional reaction conditions such as a reaction

Sro-la2o3/cao(slc) catalysts have been found to be active for the oxidative coupling of methane (ocm), but the lattice oxygen of them is only active for total oxidation as revealed by the studies of in - situ ft-ir on the interaction between ch4 and

The kinetics of CO desorption on Pd(111) has been studied by using isotope switch method under the gas-phase pressures of single isotope and mixed ones. The experiments show that the desorption kinetics is non-linear and is first order plus second or

The mechanism of the synthesis of platinum carbonyl clusters Pt-3(CO)(6)](n)(2-) (n=3, 4) in cages of NaY was studied by IR, EXAFS (CO)-C-13 exchange reaction and NO interaction. The results suggest that oxidized Pt species in NaY cages reacts with C

The catalysts derived from the reduction of intrazeolite Pt carbonyl clusters [Pt-12(CO)(24)](2-)/NaY and [Pt-9(CO)(18)](2-)/NaY were characterized by EXAFS and chemisorption techniques. EXAFS analysis gave RPt-Pt=2.74 angstrom, C.N.=4.2 for Pt-12/Na

A series of NaCl/B2O3/Fe2O3 catalysts having a B/Fe atomic ratio from 0 to 0.3 and 0.25 of Na/Fe atomic ratio were prepared for the oxidative coupling of methane (OCM). It was noted that NaCl and B2O3 show a synergetic effect: NaCl/Fe2O3 produces mai

t-Butylacetylene was polymerized using MoCl 5 as catalyst. Some factors influencing metathesis polymerization of t-butylacetylene were studied, including co-catalysts (Ph 2 Si(OEt) 2 , CH 3 Si(OEt) 3 , Et 3 SiH, etc.). All of the co-catalysts bring a
