The synthesis of thiophene from the reaction of n-Butanol and carbon disulfide was performed in a fixedbed reactor in the presence of promoted chromia on γ-alumina. A high selectivity to thiophene (87%) and a long lifetime of the catalyst (55 hour) was obtained at 450 o C with a 1 : 6 n-Butanol to carbon disulfide molar ratio and LHSV 1 h −1 over γ-Al 2 O 3 promoted by 7% K 2 CO 3 with 15% Cr 2 O 3 loaded. The catalytic behavior of these catalysts can be attributed to their dual-functional acidity and dehydrogenating and cyclized properties.

A new LiFePO4-based phase composite LiFe0.95Ti0.05PO4/(C+LiFeP2O7)was synthesized by solid state method . The amorphous carbon and phosphate LiFeP2O7 consisted of the protective layer and coated the surface of the solid solution LiFe0.95Ti0.05PO4 The phosphate LiFeP2O7 was detected though XRD(X-ray diffraction)and CV(cyclic voltammetry).Morphology of the composite was observed by scanning electron microscope(SEM)and Transmission electron microscopy (TEM), it illustrated Ti4+ had been induced into the crystal lattice of LiFePO4 and formed the solid solution LiFe0.95Ti0.05PO4.The data of charge-discharge tests showed the composite had excellent electrochemical properties. Initial charge and discharge capacity of LiFe0.95Ti0.05PO4/(C+LiFeP2O7) had reached 157.9mAh/g and 155.2mAh/g at the rate of 0.1 C, respectively. At 1C, the discharge capacity of the composite remained 125mAh/g after 100 cycles.
