Carbon nanotubes(CNTs) with abundant surface defects are prepared by a liquid oxidation and thermal annealing method. The defective CNTs-D supported Ba–Ru/CNTs-D catalysts exhibit superior catalytic performance in ammonia synthesis with a TOF be increased up to 0.30 s-1, which is 2.5 times of oxidized CNTs-O supported Ba–Ru/CNTs-O catalysts and 5 times of the Ba–Ru/CNTs. The characterizations by CO chemisorption, transmission electron microscope, Raman, and X-ray photoelectron spectroscopy revealed that the uniformly well dispersed Ru NPs can be stabilized on the defective sites of CNTs-D. The great improvement of the catalytic performance and stability of the Ba–Ru/CNTs-D is contributed to the strong interaction between Ru NPs and surface defect of the CNTs.

Heterogeneously catalyzed hydrolytic dehydrogenation of ammonia borane is a remarkable structure sensitive reaction. In this work, a strategy by using polyoxometalates(POMs) as the ligands is proposed to engineer the surface and electronic properties of Pt/CNT catalysts toward the enhanced hydrogen generation rate and durability. Three kinds of POMs, i.e., silicotungstic acid(STA), phosphotungstic acid(PTA)and molybdophosphoric acid(PMA), are comparatively studied, among which the STA shows positive effects on the catalytic activity and durability. A catalyst structure-performance relationship is established by a combination of kinetic and isotopic analyses with multiple characterization techniques, such as HAADF-STEM, EDS, Raman spectroscopy and XPS. It is shown that the STA compared to the other two POMs can increase the Pt binding energy and thus promote the reaction. The insights demonstrated here could open a new avenue for boosting the reaction by employing the POMs as the ligands to engineer the catalyst electronic properties.

Understanding the nature of Pt active sites is of great importance for the structure-sensitive base-free oxidation of glycerol. In the present work, the remarkable Pt particle size effects on glycerol conversion and products formation from the oxidation of the primary and the secondary hydroxyl groups are understood by combining the model calculations and DFT calculations, aiming to discriminate the corresponding dominant Pt active sites. The Pt(100) facet is demonstrated to be the dominant active sites for the glycerol conversion and the products formation from the two routes. The insights revealed here could shed new light on fundamental understanding of the Pt particle size effects and then guiding the design and optimization of Pt-catalyzed base-free oxidation of glycerol toward targeted products.

The Shanwang Basin is a small Cenozoic sedimentary basin located in Linqu county, Shandong *** Shanwang Formation, especially the diatomaceous shale member, contains diverse and finely preserved flora and fauna fossils （Fig. 1）. Previous paleontological study and radiometric dating show that it was formed in the Miocene. However, on the precise age of the formation, there are such different opinions as Late Miocene, Middle Miocene, Early stage of Middle Miocene, etc.

Red beds are not entirely red sometimes, in which grey-green spheroids or irregular spots can be found. However, the formation mechanism of grey-green spheroids or irregular spots in red beds is not clear so far. Samples taken from well JK1 in Jiaozhou area of Jiaolai Basin displayed that the reduction spheroids have more Vanadium (V) element, less TFe3O4 and Lead (Pb) element, almost the same content of other elements such as FeO and so on, comparing the red parts of the samples. The existence of organisms can explain the existence of green reductive spheres in the red beds formed under the oxidation environment.

通过对灵山岛野外地质考察及总结前人资料,并利用节理、岩墙和褶皱等应力感应构造的测量分析,得出研究区早白垩世可能存在四期构造作用:莱阳期NW向伸展形成近海盆地,莱阳期末期NW向挤压反转作用,青山期NW向伸展裂谷作用和早白垩世末期NW向挤压反转。灵山岛早白垩世两期伸展作用可能是分别对华北地区增厚地壳或岩石圈重力垮塌和岩石圈拆沉的响应,而两期挤压反转作用可能是研究区由伊泽奈崎板块NW向俯冲消减向太平洋板块NW向俯冲过渡的结果。

在胶莱盆地南缘开展1：5万区调工作的基础上，对胶莱盆地南缘的白垩纪青山群火山岩进行了层型剖面实测及系统采样，经过化学分析及数据整理，得出胶莱盆地南缘白垩纪青山群火山岩SiO2的含量为51．08％～74．86％，全碱（Na2O＋K2O）含量的变化范围为3．2％～8．8％，Al2O3的含量集中于13．18％～17．3％之间，全铁（TFe2O3）含量的变化范围在0．86％～10．48％之间；火山岩微量元素强烈富集大离子亲石元素La和Nd，亏损高场强元素Nb、P和Ti，轻稀土元素（LREE）相对富集，重稀土元素（HREE）相对亏损。后夼组与石前庄组火山岩的地球化学特征较相似，以酸性火山岩为主，而八亩地组和方戈庄组火山岩的地球化学特征较相似，以中一中偏基性火山岩为主；后期喷发的石前庄组与方戈庄组火山岩较前期的后夼组、八亩地组火山岩碱性物质含量增加。通过综合分析得出，胶莱盆地南缘白垩纪青山群火山岩是一套中一酸性过铝质、富钾钙碱性为主的火山岩，其四个不同喷发期次的岩浆应来源于同一岩浆源——下地壳，可能与扬子板块的俯冲作用有关，岩浆形成演化过程中表现出强烈的结晶分异作用，基于青山群火山岩岩性及岩浆源分析，认为其不属于典型的双峰式火山喷发。

陆相红层因为其含古生物化石稀少给高精度生物、年代地层的对比带来了较大的困难。旋回地层学可以将地层与地时结合起来,解决地层沉积的时限问题。基于前人在对胶莱盆地K/Pg界线识别的基础上,主要利用了一维连续小波变换尺度分析法与频谱分析法对胶莱盆地胶州组K/Pg界线之下、晚白垩世红土崖组玄武岩夹层之上的陆相红层进行旋回地层分析,认为胶莱盆地晚白垩世的陆相红层中保存有米兰科维奇旋回,岁差、斜率和偏心率各个周期在不同的层段响应程度略有不同。根据旋回识别结果及K/Pg界线建立了“浮动天文年代标尺”,推测在66~67.77 Ma期间,胶莱盆地陆相红层的平均沉积速率约为5.15 cm/kyr,胶州地区[(67.77~73)±0.3]Ma期间为玄武岩岩浆冷凝固结形成玄武岩进而遭受风化剥蚀及构造沉降的时期,红土崖组与胶州组的时间界线约为67.28 Ma,红土崖组玄武岩夹层的年龄应早于67.77 Ma。
