1Ternary Ni-Co-Fe oxyhydroxide oxygen evolution catalysts:Intrinsic activity trends,electrical conductivity,and electronic band structure显示文摘Nickel-,cobalt-,and iron-based(oxy)hydroxides comprise the most-commonly studied electrocatalysts for the oxygen-evolution reaction(OER)in alkaline solution.A fundamental understanding of composition-structure-activity relationships for mixed-metal Ni-Co and Ni-Co-Fe(oxy)hydroxides is important to guide the design of advanced OER catalysts.Here we use cyclic voltammetry,chronopotentiometry,inductively-coupled plasma-optical emission spectroscopy,and in situ electrical conductivity measurements to characterize the properties and activity of various compositions of Ni-Co-Fe(oxy)hydroxides prepared by cathodic co-electrodeposition.Consistent with previous studies,we find Fe is essential for the mixed-metal(oxy)hydroxides to achieve high OER activity.In the rigorous absence of Fe(achieved by using specially cleaned electrolytes),the most-active Ni-Co(oxy)hydroxide composition has an OER turn-over frequency only twice that ofpure Co(oxy)hydroxide,suggesting minimal synergism between the two metals.The addition of Co to Ni-Fe(oxy)hydroxides shifts the onset of electrical conductivity to lower potentials,but has little effect on the intrinsic OER activity,with the most-active Ni-Co-Fe(oxy)hydroxide having an OER turn-over frequency only -1.5 times that of the Ni-Fe(oxy)hydroxides.The magnitudes of the electrical conductivities are similar for all the compositions measured.Density-functional-theory-calculated projected density of states show a significant contribution of all chemical elements at the valence band edge of the mixed-metal oxyhydroxide electronic structure,demonstrating significant electronic hybridization between the elements.The calculations suggest the involvement of all the elements in modulating the electronic structure at putative Fe-based active sites that are probably located at edges or defects in the two-dimensional oxyhydroxide sheets.Michaela Burke Stevens Lisa J.

3挪威Storgama小型源头集水区土壤和径流的天然可变性显示文摘为了提供挪威南部泰勒马克县Storgama的11个小型源头集水区(30~268 m^2)气候操控实验的基线数据,我们对位点特征和径流质量的天然可变性进行了分析。各位点径流中的年平均浓度的变异系数为26%~61%,其中总有机碳(TOC)和碳氮比(C/N)最小而无机氮(N)值最大。这些集水区的无机氮、TOC和总磷浓度比附近更大的Storgama集水区(0.6 km^2)高2~5倍。径流中的TOC和TON浓度随着土壤碳和氮含量以及集水区土壤体积而增加。对于径流中的硝酸盐(NO_3)和铵来说则相反。在潮湿年份,裸岩的比例是径流中年平均NO_3浓度的主要指示指标。Line Tau Strand Stle Haaland Φyvind Kaste Arne O.Stuanes 丁莉 2008AMBIO-人类环境杂志2008,37,1:3

6挪威Storgama小型源头集水区积雪操控实验:对无机氮淋溶的影响显示文摘我们对挪威南部山区石南荒地的小型源头集水区冬令时期土壤温度机制进行了操控实验,以研究土壤温度对径流中无机氮浓度和通量的可能影响。实验包括两个集水区土壤的隔热处理,以使土壤在整个冬季保持零上温度;另两个集水区的去除积雪处理,以促使土壤冻结。冬季土壤温度升高增加了春季径流中铵氮(NH_4)和硝酸盐(NO_3)的浓度和通量。相反,去除积雪覆盖,土壤显著冻结,则对无机氮浓度和通量没有系统的影响。我们的实验结果表明,暖冬较高的土壤温度或者较厚的积雪覆盖意味着这一地区无机氮淋溶的风险更大,而雪盖减少导致的土壤冻结事件,造成的无机氮淋溶增加的风险则不大。Φyvind Kaste Kari Austnes Live Semb Vestgarden Richard F.Wright 陶书田 2008AMBIO-人类环境杂志2008,37,1:2
7挪威Storgama小型源头集水区积雪操控实验:对总有机碳和总有机氮淋溶的影响显示文摘预期未来气候变化将引起冬季温度升高,这可能导致北温带较低和中等高度地区的雪积累降低。土壤温度和水状况的变化结果会影响总有机碳(TOC)、总有机氮(TON)的淋溶。本研究在挪威南部的山地荒野区对小型源头集水区的积雪覆盖进行操控实验,以此来量化对径流中TOC和TON浓度和通量的影响。操控实验包括除雪处理(以促进土壤冻结)和隔离处理(以阻止土壤冻结)。除雪处理导致TOC和TON浓度升高,但通量减少。隔离引起TOC浓度和通量少量降低。研究结果表明,积雪深度变化,因而土壤温度也发生变化,对所研究的山地荒野区的TOC和TON淋溶不会有严重影响。Kari Austnes Φyvind Kaste Live Semb Vestgarden Jan Mulder 张秋英 2008AMBIO-人类环境杂志2008,37,1:2

9气候变化对挪威托夫达尔河流域至邻近海域氮通量的影响显示文摘假定4种气候变化情景,利用质量运输模型(TEOTIL)可预测挪威最南部的托夫达尔河流域的硝酸盐(NO_3)通量。目前,森林、高地和开阔水体占NO_3通量的90%。2071~2100年的气候情景显示,温度将增加2~4℃,降水会增加3%~11%。利用气候实验和长期监测来估算未来的氮(N)淋溶率。冬季将有更多的水流经陆地流域,而春季则较少。预计从托夫达尔河到邻近的托普达尔峡湾,年NO_3通量保持不变,但是,冬季运送的NO_3要多,春季要少。可以预计,沿海水域藻类大量繁殖会发生在当年的更早时候。主要的不确定来源是储存在土壤有机物中的氮的长期命运及森林管理的影响。Richard F.Wright Φyvind Kaste Heleen A.de Wit Torulv Tjomsland Mirjam Bloemerts Jarle Molvr John Rune Selvik 高战朝 2008AMBIO-人类环境杂志2008,37,1:2
