Preparation of PdCoIr Tetrahedron Nanocatalysts and Its Performance toward Ethanol Oxidation Reaction

钯(Pd)基催化剂是直接乙醇燃料电池研究中广泛使用的催化剂,进一步提升其性能是推动燃料电池发展的重要方向。本文用一步水热法制备出四面体结构PdCo(PdCo tetrahedron,记为PdCo-TH)和少量铱(Ir)掺杂的PdCo四面体合金纳米粒子(记为PdCoIr-TH)。经TEM、ICP、XPS及CV等表征证实,PdCoIr-TH为三元合金纳米粒子,且掺杂的Ir元素倾向分布在催化剂表层。相比于商业Pd/C催化剂,PdCo-TH/C和PdCoIr-TH/C对乙醇电氧化的催化性能显著增强。研究结果表明,Pd9Co1Ir0.1-TH/C在低电位(< -0.25 V)下具有最高的乙醇电氧化活性和稳定性。Ir掺杂不仅提高了催化剂抗CO毒化的能力还有利于乙醇起始氧化电位负移。同时,随着Ir含量的增加,所制备的纳米催化剂的乙醇电氧化C1产物选择性也随之升高。针对不同组成催化剂反应性的差异,本文认为Co与Ir位点上容易产生OHad物种,这将有利于活性Pd位点上乙醇电氧化中间反应物种的有效转化。除了以上的各位点间的协同效应,三元合金的形成,进一步调控了Pd的d带电子结构,从而促进了催化剂反应性的改变。As a new energy conversion device, direct ethanol fuel cells (DEFCs) are widely concerned because of their remarkable advantages such as high theoretical energy density and wide fuel sources. However, the rapid development of DEFCs has been severely impeded due to the sluggish kinetic process and toxic intermediates especially in their anodic reactions. Palladium (Pd)-based materials are considered to be excellent anode catalysts for DEFCs, especially under alkaline conditions. And further improving their performance is an important direction to promote the development of DEFCs. Surface structure and composition are the key factors affecting the performance of catalysts which can be improved by reasonable regulation. It is reported that high-index faceted structures and element doping are beneficial to improve the performance of catalyst. In this work, the advantages of these two strategies were used comprehensively to prepare Pd-based catalysts with high efficiency. Palladium cobalt (PdCo) and Ir-doped PdCo tetrahedron alloy nanocatalysts (denoted by PdCo-TH and PdCoIr-TH, respectively) have been successfully prepared by one-step hydrothermal method. The characterization results of TEM, ICP, XPS and CV show that the PdCo-TH binary and PdCoIr-TH ternary alloys were formed, while Ir element was mainly distributed on the PdCoIr-TH surface. Compared with the commercial Pd/C, the PdCo-TH/C and PdCoIr-TH/C exhibited the enhanced catalytic properties toward ethanol oxidation reaction in alkaline solutions. Particularly, the Pd9Co1Ir0.1-TH/C catalyst showed the best activity and stability toward EOR, especially at low potentials (< -0.25 V). And Ir sites not only resisted CO poison effectively, but also shifted the initial oxidation potential of ethanol negatively. Meanwhile, the selectivity of C1 products during the electrocatalytic oxidation of ethanol has been greatly improved with the increase of Ir content. The enhanced reactivities of PdCo-TH/C and PdCoIr-TH/C could be attributed to: (a) The coexistence of Co sites and Ir sites on the surfaces can generate OHad species which can promote the oxidation of intermediate adsorbed species on Pd sites and (b) the negative shift in electron binding energy of Pd due to the addition of Ir may make reaction intermediates desorb more difficultly, which might make the reactivity of PdCoIr-TH/C differ from that of PdCo-TH/C. This research work has demostrated a strategic approach for future development in high efficiency catalysts used for DEFCs.国家自然科学基金项目(21802112);国家自然科学基金项目(21773198)通讯作者:黄蕊,孙世刚E-mail:[email protected];[email protected]:RuiHuang,Shi-GangSunE-mail:[email protected];[email protected]厦门大学化学化工学院,固体表面物理化学国家重点实验室,福建 厦门 361005State Key Laboratory of Physical Chemistry of Solid Surfaces, Department of Chemistry, College of Chemistry and Chemical Engineering, Xiamen University, Xiamen 361005, Fujian, Chin

Legislative Fairness: A Procedural Perspective

立法程序的公平是现代法律制度中立法公平不可或缺的法理内涵。我国在立法实践中存在着“部门立法”等立法不公现象,其直接原因应归结为我国的立法程序中的制度瑕疵。为求构建公平合理的立法程序,我国应该努力推进立法参与主体的多元化、立法组织的民主化、立法过程的理性化,在立法实践中强化立法听证制度,推行立法助理制度,建立立法回避制度,适当延长人大及其常委会的会期,完善信息公开制度。 【英文摘要】Fairness in legislative procedure is an indispensable legal principle of legislative fairness in the contemporary legal framework. There are phenomena of legislative unfairness in our country’s legislative practice , such as departmental law-making ,which can be directly attributed to the flaws in our legislative procedure. In order to construct a fair legislative procedure , China should advocate and promote the plurality of law-making participants , the democratization of legislative organizations , and the rationalization of legislative process. Furthermore , the systems of legislative hearing , legislative assistance , and legislative withdrawal should be reinforced , and the legislative session of National People’s Congress and its standing committee should be prolonged to ensure full exposure and circulation of legislative information

Effects of phosphate and metal ions on alkaline phosphatase activity and kinetic parameters in Swan Lake,Rongcheng

The catalytic hydrolysis of organic phosphorus by phosphatase represents an important source of available phosphorus in surface water. To assess the effects of phosphate and metal ions on alkaline phosphatase activity and kinetic parameters,surface water samples were taken from the coastal Swan Lake water in Rongcheng. Results show that phosphate (PO_4~(3-)),hexametaphosphates (PO_3)_6~(6-),pyrophosphate (P_2 O_7~(4-)) and ß-glycerophosphate (C_3H_4O_6P)~(2-)could inhibit the alkaline phosphatase activity (APA) when their concentrations were in the range of 0.01-1mmol·L~(-1). And this inhibition effect increased with the increase of the ion concentrations. In comparison,the APA decreased 50.8%,55.8%,52.4% and 14.4% as treated by 1 mmol·L~(-1) PO_4~(3-),(PO_3)_6~(6-),P_2 O_7~(4-),(C_3 H_4 O_6 P)~(2-),respectively. The activation of APA by Al~(3+)、Co~(2+)、Pb~(2+) and Cr~(6+) increased when their concentration increased. After adding 1 mmol·L~(-1) Al~(3+),Co~(2+),Pb~(2+) and Cr~(6+) to the water,the APA increased by a factor of 2.8,3.1,2.3 and 2.7, respectively. The heavy metal Cu~(2+),Zn~(2+),Ni~(2+) were also found to have inhibition effects on APA,especially for Cu~(2+).The residual APA dramatically decreased to 62.3% at 1 mmol·L~(-1) of Cu~(2+). The significant reduction of an apparent substrate affinity (Km) and the uniform pattern of maximum APA (Vmax) were both observed when the Cu~(2+),PO_4~(3-),(PO_3)_6~(6-),P_2O_7~(4-) increased. This phenomenon indicates that Cu~(2+),PO_4~(3-),(PO_3)_6~(6-),P_2O_7~(4-) behave in competitive inhibition effects. In addition,V_(max) /K_m ratio is a good indicator for the catalytic efficiency of alkaline phosphatases in eutrophic water. This research suggests that the phosphate and metal ions can significantly influence APA and has profound implication for the transform and supplement of the organic phosphorus in eutrophic water
