Development of Solid Base Resin Catalyst for Synthesis of Propylene Glycol Methyl Ether via Addition of Propylene Oxide and Methanol

丙二醇甲醚是一种用途广泛的精细化学品，因其结构中同时具有亲油性的醚基和亲水性的羟基，素有“万能溶剂”之称。目前被广泛地用于涂料、油墨、印染、纺织、电子化学品、清洗剂等行业，同时也可用作化工原料中间体，通用性强。 丙二醇甲醚的传统生产方法是由均相酸或碱作催化剂，环氧丙烷和甲醇发生加成反应制得。但该法存在着催化剂分离困难、设备腐蚀严重、环境污染等问题，而固体碱催化剂对丙二醇甲醚的合成具有反应活性高、伯醚选择性好、催化剂易分离等优点。因此，本文制备了树脂型固体碱催化剂，并研究了其在合成丙二醇甲醚反应中的性能，具体内容如下： 1、本文以交联的聚苯乙烯微球为载体，通过嫁接法将无水哌嗪等含氮杂环负载于...Propylene glycol methyl ether (PM), an extensive used chemical, with two groups-alcohol ether and hydroxyl, owning its strong ability of hydrophilic and lipophilic properties, is known as the “universal solvent”.

Two-dimensional materials for electrocatalytic water splitting

氢能是一种高热值、无污染的洁净能源.电解水制氢被认为是一种有效利用可再生能源,如风能、太阳能等,实现能量储存和转换的前沿科技.二维材料独特的结构和电子特性使其在催化电解水反应中具有广阔的应用前景.本文系统综述了二维材料在催化电解水反应中的两个半反应——阴极析氢反应（HER）和阳极析氧反应（OER）中的关键科学问题和最新进展,并展望了该领域所面临的挑战和机遇.Hydrogen is a kind of clean energy with high calorific value and non-pollution. There are many methods for hydrogen production. Fuel processing technologies transform a hydrogen containing material such as coal, petroleum, or natural gas into a hydrogen rich stream. However, these processes need an external heat source for the reactor and produce large amounts of carbon dioxide. Hydrogen production by electrolysis of water is regarded as an advanced technology to make effective use of renewable resources, such as wind power, solar power, etc., to achieve energy storage and conversion. Water electrolysis includes hydrogen evolution reaction（HER） and oxygen evolution reaction（OER）. These reactions are normally catalyzed by precious metals, such as platinum（Pt） and iridium（Ir）-based catalysts, which limits the large-scale application of electrolysis of water. Thus, it is necessary to develop alternative catalysts with low cost and high performance. Two-dimensional（2D） materials have considerable application prospect in electrocatalysis of H2 O because of their unique structural and electronic properties. In addition, 2D materials with a reduced dimension compared with the bulk material exhibits several distinctive properties, such as high specifc surface area, high thermal and electric conductivity and more catalytic active sites. In this review, the key scientific issues and the latest advances in the two half-reactions（HER and OER） of electrocatalytic water splitting with 2D materials are systematically summarized. The mechanisms of HER and OER are discussed briefly. The involved 2D materials for HER in this work include graphene, graphene encapsulated transition-metal catalysts, g-C_3N_4 and 2D transition-metal dichalcogenides, while for OER contain layered double hydroxide（LDH） and graphene encapsulated transition-metal catalysts materials. For graphene, g-C_3N_4 and 2D transition-metal dichalcogenides, there are various techniques to enhance the catalytic activity of the materials, s国家科技部重点研发计划（2016YFA0204100,2016YFA0200200）; 国家自然科学基金（21573220）; 中国科学院前沿科学重点研究计划（QYZDB-SSW-JSC020）和中国科学院战略性先导科技专项（XDA09030100）资

Synthesis of alloy nanocatalysts with high-index facets and investigation of their electrocatalytic performance

铂族金属纳米催化剂广泛的用于燃料电池、石油化工等领域中。但是由于铂族金属价格昂贵、储量十分有限，因此如何进一步提高其催化活性、稳定性，提高其利用效率一直是相关领域研究的重要课题。基础研究表明铂族金属高指数晶面由于含有高密度的台阶原子和扭结原子，催化活性和稳定性显著优于{100}、{111}等低指数晶面。此外，对铂基合金纳米粒子的研究结果也表明，合金纳米粒子的催化性能相对于单金属有很大的提高。因此制备表面为高指数晶面结构的铂族金属合金纳米晶体是显著提高催化剂性能的有效途径。但是由于较高的表面能以及晶格不匹配等原因，常规方法很难制备出高指数晶面铂族金属合金纳米粒子。 本论文中，我们发展了双金属纳...Platinum-group metal nanomaterials are widely used catalysts applied in fuel cells, petrochemical industry and other important fields.

Analysis and estimation of learning style in Library

根据南京师范大学社科专业图书馆2016年4.22—5.22的在馆读者信息,以可反映学习状态的参数——在位人数、总占位数及吃零食、玩手机、用电脑、睡觉、交谈、学习等的人数,对该馆内读者的实时学习状态进行了抽样分析。首先,通过读者出入馆信息确定了状态参数的抽样时间为上午10—11时,并定义学风指标为学习人数除以实际在位人数;再对抽样时间点的学习状态参数及天气情况建立模型。通过建立负二项回归模型、广义线性模型,并应用稳健性检验方法得到了在馆读者的实时学习状态。结果表明：学风指标区间为60%-80%,处于良好状态;8—11时的进馆人数与学习氛围呈正相关关系,天气因素对馆内读书人数有较大影响,其是无法改变的外生变量,可通过改善图书馆的硬件设施与服务质量提升进馆人数;模型估计的学风指标与实际情况基本一致。Based on the present readers＇ information from Nanjing Normal University professional library between Apr 22 th and May 22 th in 2016, the readers＇ real-time learning style are analyzed by some parameters reflecting learning status such as the present number, the total number of occupied seats, and the numbers of who are eating snack, playing phones, using computer, sleeping, talking and learning. Firstly, the readers＇ entrance information are used to ensure that the sampling time of status parameters is 10—11 a.m. each day, and we define the learning style index as the number of who are learning divided by the real number of who are present seated. Secondly, a model is put forward based on the learning status parameters and weather conditions from sampling time point. By the Negative Binomial Regression, Generalized Linear Model and robust test, the real-time learning status of present readers is put forward. The results show that the interval of the learning style is 60%-80%, which is good; there is a positive correlation between the entrance number of 8—11 o＇clock and the learning atmosphere. The weather condition is an unchanged exogenous variable that affects the number of readers. The improved library＇s hardware facilities and service quality can increase the entrance number. The index made by the model is basically consistence with the actual circumstance.国家自然科学基金（61374080）; 江苏省自然科学基金（BR20161552
