Cathodic oxygen reduction reaction （ORR） is a highly important electrochemical reaction in renewable-energy technologies. In general, the surface area, exposed facets and electrical conductivity of catalysts all play important roles in determining their electrocatalytic activities, while their performance durability can be improved by integration with supporting materials. In this work we have developed a method to synthesize hybrid structures between PtPd bimetallic nanocages and graphene by employing selective epitaxial growth of single-crystal Pt shells on Pd nanocubes supported on reduced graphene oxide （rGO）, followed by Pd etching. The hollow nature, {100} surface facets and bimetallic composition of PtPd nanocages, together with the good conductivity and stability of graphene, enable high electrocatalytic performance in ORR. The obtained PtPd nanocage-rGO structures exhibit mass activity （0.534 A.m-1） and which are 4.4 times and 3.9 times greater than the specific activity （0.482 mA-cm-2） corresponding values for Pt/C.

Compared with marine facies shale strata,lacustrine shale strata are more complicated in geological conditions,and thus more difficult to explore and *** realize economic exploration and development of lacustrine shale oil,the geological regularities of accumulation and high yield of retained movable petroleum in shale should be understood *** this work,taking the shale strata of Kong 2 Member and Sha 3 Member in the Paleogene of Huanghua depression in the Bohai Bay Basin as examples,based on the previous joint analysis results of over ten thousand core samples and the latest oil testing,production test and geochemical data of more than 30 horizontal wells,accumulation conditions and models of retained movable petroleum in lacustrine shale were studied *** study shows that at moderate organic matter abundance(with TOC from 2%to 4%),shale strata have the best match between oil content and brittleness,and thus are rich in oil and good in *** ancient lake basin size and moderate sediment supply intensity are the internal factors leading to best coupling of organic matter abundance and brittle mineral content in the shale *** thermal evolution maturity of Ro of 0.7%–1.0%(at burial depth of 3200 to 4300 m)is the interval where oil generation from thermal evolution and oil adsorption by kerogen in shale layers match best,and retained movable petroleum is high in *** diagenetic evolution stage(3200 to 4300 m in the middle diagenetic stage A)is conducive to the formation of a large number of dissolved pores and organic matter pores,which provide storage space for shale oil *** development degree of natural fractures(without damaging the shale oil roof and floor sealing conditions)is conducive to the storage,seepage and preservation of shale *** research results have overthrown the general understanding that high organic matter abundance,high maturity,and high development degree o

在层序地层学研究的基础上,应用有机地球化学等手段开展歧口凹陷古近系层序地层格架中烃源岩成烃环境研究,探讨优质烃源岩分布规律及主控因素。歧口凹陷古近系可以划分为3个二级层序,不同层序地层中均发育多套有效烃源岩,但烃源岩非均质性强。根据古环境、古生态、古气候等方面的差异性将不同层序划分为6种沉积有机相类型,其中近源—咸化湖—强还原—植源藻源相优质烃源岩最为发育。纵向上,优质烃源岩主要发育于断陷湖盆稳定湖泛期,尤其是SQEs32上部—SQEs31、SQEs1下上部—SQEs1中;横向上受物源条件和水体环境的控制,优质烃源岩在歧口凹陷南部较为发育;沉积环境和成烃环境共同控制优质烃源岩空间发育。

黄骅坳陷发育了石炭-二叠系煤系烃源岩、古近系孔二段和沙三段暗色泥岩等3套有利烃源岩,导致原油成因及来源复杂多样.为进一步明确中-古生界原油成因与来源,在前人研究基础上明确了研究区3套烃源岩的生标化合物特征,并根据20个原油及油砂样品的碳同位素组成、生物标志化合物参数及饱和烃色谱和色-质谱图等特征,对研究区的原油成因类型进行划分并展开精细油源对比,认为黄骅坳陷南区围绕沧东-南皮凹陷分布的潜山是孔二段烃源岩生成油气的潜力分布区带;坳陷中北区沙三段烃源岩发育较好的潜山带,则是沙三段烃源岩生成油气的主要聚集区;而石炭-二叠系烃源岩生成原油则主要分布在新生代断裂不发育的褶皱潜山带,如乌马营潜山、孔西潜山等将是煤成油的有利勘探区带.研究结果表明:黄骅坳陷中-古生界原油可划分为3个大类6个亚类,且不同成因类型原油的分布特征受控于3套有效烃源岩的展布范围,其中I类原油主要源自石炭-二叠系煤系烃源岩,其碳同位素重于-28‰、三环萜烷含量高、Ts/Tm比值普遍低于1.0、C27-29甾烷呈"L"型分布,平面上分布范围局限,仅在孔西、乌马营等褶皱型潜山发育,且Ⅰ1类原油中混入了沙三段烃源岩贡献;Ⅱ类原油主要来自沙三段烃源岩,碳同位素较重、三环萜烷含量中等、Ts/Tm比值较小、C27-29甾烷呈近"Ⅴ"型分布,主要分布在坳陷中区的北大港潜山和歧北潜山,且Ⅱ2类原油中混入了石炭-二叠系烃源岩的贡献;而Ⅲ类则主要源自孔二段烃源岩,原油碳同位素轻于-30‰、三环萜烷含量低、Ts/Tm普遍大于1.0、C27-29甾烷呈反"L"型分布,仅分布在孔南地区,且Ⅲ1类原油中混入了少量的石炭-二叠系来源.
