摘要：In this study,we report a new small molecule acceptor(named TT-4 F)which uses 3,6-dimethoxylthieno[3,2-b]thiophene(TT)as theπ-*** of 0.05 weight ratio amount of TT-4 F into the host binary blend of PTB7-Th:IEICO-4 F,resulting in a ternary blend in a weight ratio of 1:1:0.05,enables increased open-circuit voltage(Voc),short-circuit curre nt-density(Jsc),and fill-factor(FF)at the same ***,12.1%efficiency is *** to the 3-(2-ethylhexyloxylthiophene)bridge on IEICO-4 F,the additional methoxyl group on the TT-6 position is involved in the lowest unoccupied molecular orbital(LUMO)and the largerπ-system on TT increases the electron-donating nature,both of which help to raise the LUMO level,one reason of the increased *** addition of 0.05 TT-4 F,the hole mobility is increased,the monomolecular recombination is reduced,and the charge dissociation and collection is *** of these contribute to the increased Jsc and FF.

摘要：Tailoring the microstructure of pristine TiO2 is essential to narrow its band gap and prolong the charge lifetime. In particular, strategies involving fluorine have been used successfully to tune the surface chemistry, electronic structure, and morphology of TiO2 photocatalysts to improve their photocatalytic activity based on the strong complexation between fluoride ions and TiO2 and the high electronegativity of fluorine. In this review, we summarize the strategies involving fluorine to establish highly efficient TiO2 photocatalytic systems or fabricate highly efficient TiO2 photocatalysts. The main fluorine effects(i.e. the effects of fluorine on photocatalysis) include the following four aspects:(1) Surface effects of fluoride on TiO2 photocatalysis,(2) effects of fluorine doping on TiO2 photocatalysis,(3) fluoride-mediated tailoring of the morphology of TiO2 photocatalysts, and(4) the effects of fluorine on non-TiO2 photocatalysis. Additionally, the unique applications of these fluorine effects in photocatalysis, including selective degradation of pollutants, selective oxidation of chemicals, water-splitting to produce H2, reduction of CO2 to produce solar fuels, and improvement of the thermostability of TiO2 photocatalysts, are reviewed.

摘要：Ti^（3＋） self-doped anatase three-dimensional（3D） TiO_2 hollow nanoboxes were synthesized via a topological transformation process involving template participation by a facile one-pot hydrothermal treatment with an ethanol solution of zinc powder and TiOF_2. It is worth noting that the 3D TiO_2 hollow nanoboxes are assembled from six single-crystal nanosheets and have dominant exposure of the {001} facets. It is found from EPR spectra that adding zinc powder is an environment-friendly and effective strategy to introduce Ti^（3＋） and oxygen vacancy（Ov） into the bulk of 3D hollow nanoboxes rather than the surface, which is responsible for their enhanced visible photocatalytic *** photocatalytic activity was evaluated by measuring the formation rate of hydroxide free radicals using 7-hydroxycoumarin as a probe. The sample prepared with zinc/TiOF_2 mass ratio of0.25 exhibited the highest RhB photodegradation activity under visible-light irradiation with a degradation rate of 96%, which is 4.0-times higher than that of pure TiO_2. The results suggest a novel approach to construct in-situ 3D hierarchical TiO_2 hollow nanoboxes doped with Ti^（3＋） and Ov without introducing any impurity elements for superior visible-light photocatalytic activity.

摘要：发布绩效评估榜单是第三方评估过程中经常采取的一种日常操作。在实践中,作为一种选择方式,许多项目评估方会选择性地公开绩效优良的评估对象的工作业绩,而对较差部门的评估结果不予以公开。那么,这种选择性公开的行为会对评估对象的响应行为造成怎样的影响?以政府门户网站建设的第三方评估数据为基础,通过断点回归设计实证检验了第三方评估的绩效公开与政府响应之间的关系。研究发现:公开第三方评估的结果有利于增强评估对象之间的竞争;对于进入公开榜单的优秀单位而言,公开会增强其持续学习行为;同时,与未进入公开榜单的对象相比,公开榜单的行为会降低评估对象在既有评估指标上的努力。
