借助催化剂性能评价、XRD、电导率测定、H2-TPR和XPS技术考察助剂Ag对钼磷酸催化剂丙烷氧化脱氢性能和催化剂性质的影响。结果表明,在Ag-Mo-P-O催化剂中形成Mo6++Ag0 Mo5+(Mo4+)+Ag+的氧化-还原循环,并且在催化剂中AgMoO2PO4和MoO3两相之间存在由"一致性界面"引起的协同效应,提高了催化剂的氧化还原性。在催化剂中添加适量的Ag,有助于获得高丙烯选择性和高收率。

Surface-enhanced Raman scattering （SERS） is a nanostructure-based vibrational spectroscopy with extremely high detection sensitivity up to single molecule level. However, it is in principle difficult if not impossible to directly use SERS to study atomically flat single-crystal surfaces that cannot effectively support the strong surface plasmon resonance （SPR）. As a consequence, SERS has not been well adopted by the surface science community. Recently, its application to atomically-flat single crystal surfaces has been realized to a large extent by devising and utilizing two types of nanostructure based on the borrowing SERS activity strategy.

A preliminary study of the variation of phytoplankton absorption coefficients in the northern South china Sea

引用

Acta Oceanologica Sinica 2009年第5期28卷 17-29页

作者： WU Jingyu HONG Huasheng SHANG Shaoling DAI Minhan LEE Zhongping LI Shaojing state key laboratory of Marine Environmental Science Xiamen University Xiamen 361005 China Department of Oceanography Xiamen University Xiamen 361005 China Naval Research Lab Code 7333 Stennis Space Center MS 39529 USA

The temporal and spatial variabilities of phytoplankton absorption coefficients （a ph （λ）） and their relationships with physical processes in the northern South china Sea were examined, based on in situ data collected from two cruise surveys during May 14 to 25, 2001 and November 2 to 21, 2002. Significant changes in the surface water in a ph values and B/R ratios （a ph （440）/a ph （675）） were observed in May, which were caused by a phytoplankton bloom on the inner shelf stimulated by a large river plume due to heavy precipitation. This is consistent with the observed one order of magnitude elevation of chlorophyll a and a shift from a pico/nano dominated phytoplankton community to one dominated by micro-algae. Enhanced vertical mixing due to strengthened northeast monsoon in November has been observed to result in higher surface a ph （675）（0.002–0.006 m-1 higher） and less pronounced subsurface maximum on the outer shelf/slope in November as compared with that in May. Measurements of a ph and B/R ratios from three transects in November revealed a highest surface a ph （675） immediately outside the mouth of the Zhujiang （Pearl） River Estuary, whereas lower a ph （675） and higher B/R ratios were featured in the outer shelf/slope waters, demonstrating the respective influence of the Zhujiang River plume and the oligotrophic water of the South china Sea. The difference in spectral shapes of phytoplankton absorption （measured by B/R ratios and bathochromic shifts） on these three transects infers that picoprocaryotes are the major component of the phytoplankton community on the outer shelf/slope rather than on the inner shelf. A regional tuning of the phytoplankton absorption spectral model （Carder et al., 1999） was attempted, demonstrating a greater spatial variation than temporal variation in the lead parameter a 0 （λ）. It was thus implicated that region-based parameterization of ocean color remote sensing algorithms in the northern South china Sea was mandatory.
