After concentration in a rotary evaporator， the obtained material was dried in air at 383 K overnight and subjected to preliminary reduction with a 1N2/3H2 stream at 698 K， and then cooled in 1N2/3H2 atmosphere. The potassium promoter was introduced by incipient wet impregnation with KNO3 solution at room temperature with molar ratio of K+ /Ru = 5/1. After stirring for 6 h and infusing for 24 h， the samples were dried in a rotary evaporator at 343K and then dried in the air at 383K for 12 h. The ammonia synthesis activities of the catalysts with about 35-60 meshes were evaluated by 1N2/3H2 flow of 2100 mL/h at 0.2 MPa from 623 K to 773 K. The amount of effluent ammonia was determined by titration method. As we can see from the Table 1， under the same reaction conditions， the catalyst K-Ru/Mg(Al)O exhibited the highest activity， 38.42 mL NH3•h-1•g-1 at 673K， 3 times more active than K-Ru/MgO， 12.88 mL NH3•h-1•g-1 at 748K. This means that selection of supports takes great effects on the activity of catalysts. The ammonia synthesis activity of different supports are K-Ru/Mg(Al)O > K-Ru/Mg-Al-Ca(1) > K-Ru/Mg-Al-Ca(2) > K-Ru/Al2O3 > K-Ru/CaO > K-Ru/MgO. The combinatorial supports showed higher activity than single supports. However， the sequence of temperature corresponding to the highest activity is just opposite to that of the activity. The optimal temperature for K-Ru/Mg(Al)O， 673K， is the lowest of all， on the contrary， that of K-Ru/MgO is the highest， 748K. The Mg(Al)O has a larger surface area of 140.95 m2•g-1 ， similar to γ-Al2O3， 110-180 m2•g-1 . The other two combinational supports have little surface areas but higher activities than Al2O3. It suggested that the activity of the catalyst is influenced not only by the dispersion of Ru crystals but also by the crystal structure of the supports. Table 1 Ammonia synthesis activities and BET surface areas Catalyst Optimal activity Highest activity Surface area of support temperature(K) (NH3/mL•h-1•g-1) (m2•g-1) K-Ru/MgO 748 12.88 K-Ru/Al2O3 698 23.79 K-Ru/CaO 723 23.22 K-Ru/Mg(Al)O 673 38.42 140.95 K-Ru/Mg-Al-Ca(1) 698 30.75 29.10 K-Ru/Mg-Al-Ca(2) 698 26.12 14.69 Acknowledgments This work was supported by the NNSF of China (20273053， 20023001 and 29933040)， the 973 Programming (001CB108906) and the NSF of Fujian province (E0310001).

In this paper， the degradation of an azo dye Orange G (OG) on nitrogen-doped TiO2 photocatalysts has been investigated under visible light and sunlight irradiation. Under visible light irradiation， the doped TiO2 nanocatalysts demonstrated higher activity than the commercial Dugussa P25 TiO2， allowing more efﬁcient utilization of solar light， while under sunlight， P25 showed higher photocatalytic activity. According to the X-ray diffraction (XRD)， X-ray photoelectron spectroscopy (XPS) and UV–vis spectra analyses， it was found that both the nanosized anatase structure and the appearance of new absorption band in the visible region caused by nitrogen doping were responsible for the signiﬁcant enhancement of OG degradation under visible light. In addition， the photosensitized oxidation mechanism originated from OG itself was also considered contributing to the higher visible-light-induced degradation efﬁciency. The effect of the initial pH of the solution and the dosage of hydrogen peroxide under different light sources was also investigated. Under visible light and sunlight， the optimal solution pH was both 2.0， while the optimal dosage of H2O2 was 5.0 and 15.0 mmol/l， respectively. Azodyes， which are characterized by the presence of one or more azo bonds ( N N )， are among the most notorious widespread environmental pollutants associated with textile，cosmetic， food colorants， printing， and pharmaceutical indus-tries. Because of their non-degradability， toxicity， potential mutagenicity and carcinogenicity， wastewaters originating from these dyes production or application industries pose a major threat to the surrounding ecosystems and human beings’ health.[1–3].Environmental concerns and the need of meeting the strin-gent international standards for rejecting wastewaters has made the development of novel and cost-effective processes for the puriﬁcation of azo dyes efﬂuents an issue of major technological importance. 展开

If you had to choose the single most important discovery of the 20th century， you would have a real dilemma on your hands. In just 100 years， the world changed completely. Amazing discoveries were made in medicine， communications and transport， not to mention our knowledge of the world and space . Medical advances ranged from discovering the causes of diseased under microscopes to surgical procedures replacing diseased organs with donated ones.Communications changed with the introduction of mobile phones and the way we correspond went from writing letters to emailing. We started flying around the world and meanwhile， scientists figured out how to spilt the atom， previously thought to be the smallest particle of matter in the universe. Although it is impossible to choose the most important discovery， it is possible to single out a few pioneers of the 20th century.Here are five of them. 展开
