By using copper manganese sulfated and lanthanum nitrate as raw materials, and NaOH as precipitating agent, the copper-manganese-lanthanum mixed oxides were prepared through co-precipitation method. The catalyst samples were characterized by XRD, TPR and TPD, and the catalytic properties on water gas shift (WGS) reaction were studied. The results show that, La doping didn’t change the crystal structure, but the sample crystallinity was deteriorated. Cu-Mn/La-0.5 sample reduction temperature was low and the adsorption quantity of activated CO2 was large, which implied that copper and manganese components have good metal synergic effect, lower temperature activity and thermal stability.

Oxygen adsorption and CO2produced of samples at different adsorption temperatures was investigated, Combined with thermal analysis method, the combustion properties of coal samples was determined. The results show that the oxygen adsorption capacity and CO2produced of the samples increase and later decrease with the enhanced of pyrolysis degree. In the process of low-temperature oxidation, coal molecular side chains break, then H2O, CO, CO2and so on are detected in turn; with the enhanced of pyrolysis degree, it reveals that combustion reaction activity decreased and spontaneous combustion tendency weakened.

The steam gasification experiment of FJC lignite, BL lignite, SH bituminous and TT anthracite were carried out by using an own design WFSM-3060TL Catalyst Evaluation Unit apparatus. The infulence of coal rank on the steam gasification activity was investigated. Experiment conditions: heating rate:15°C/min (25°C-500°C), 2°C/min (500°C-850°C). The resuts show that gasification of lignite is better. With the deepening of coal rank, the steam gasifiction reactivity of coal samples decreases obviously, the higher the coal rank is, the worse the gasification reactivity is.

The effects of Cu/Mn ratio on the activity and stability of Cu-Mn catalysts for the water-gas shift reaction (WGSR) were investigated. Activity tests showed that the Cu-Mn catalyst while the ration of Cu to Mn is 1:1 displayed higher activity and better stability than that of others catalysts. The BET , XRD and TPR results revealed that the Cu-Mn catalyst while the ration of Cu to Mn is 1:1 led to higher surface area, a more stable catalyst structure and suitable reduction performance, in turn leading to better catalytic behavior for the Cu-Mn catalyst.

Silicate strontium phosphor for white light LEDs was synthesized by high temperature solid-state method. The structure, surface, excitation and emission spectra of Sr3SiO5: Eu2+ phosphor which contain different mass fractions of BaF2 were measured. The results show that BaF2 quantity affects the structure, surface and spectra of Sr3SiO5: Eu2+ sample. The sample has the best properties when the BaF2 concentration comes to 2.0wt%. The structure of sample is tetragonal phase Sr3SiO5. The emission and excitation spectra peaks locate respectively at 575nm and 537nm. The samples can be excited by InGaN blue chip. The emission peaks appeared apparent red shift with the increase of BaF2 concentration. A white light emission spectrum with good color rendition was obtained by coupling the phosphor with blue chip.
