Palladium(Pd) nanostructures are highly promising electrocatalysts for the carbon dioxide electrochemical reduction(CO_(2) ER). At present, it is still challenge for the synthesis of Pd nanostructures with high activity, selectivity and stability. In this work, a facile PdII-complex pyrolysis method is applied to synthesize the high-quality one-dimensional heterostructured Pd/Pd O nanowires(Pd/Pd O H-NWs).The as-prepared Pd/Pd O H-NWs have a large electrochemically active surface area, abundant defects and Pd/Pd O heterostructure. Electrochemical measurement results reveal that Pd/Pd O H-NWs exhibit up to 94% CO Faraday efficiency with a current density of 11.6 m A cm^(-2) at an applied potential of -0.8 V. Meanwhile, Pd/Pd O H-NWs can achieve a stable catalytic process of 12 h for CO_(2) ER. Such outstanding CO_(2) ER performance of Pd/Pd O H-NWs has also been verified in the flow cell test. The density functional theory calculations indicate that Pd/Pd O heterostructure can significantly weaken the CO adsorption on Pd sites, which improves the CO tolerance and consequently enhances the catalytic performance of Pd/Pd O H-NWs for CO_(2) ER. This work highlights a facile complex pyrolysis strategy for the synthesis of Pd-based CO_(2) ER catalysts and provides a new application instance of metal/metal oxide heterostructure in electrocatalysis.

*** Carbon dioxide reduction(CO_(2)RR)technology has attracted much attention in recent years and can effectively decrease the greenhouse effect and simultaneously achieve chemical energy storage[1].In the electrochemical process,a large overpotential is generally required to activate inert CO_(2)molecules,resulting in the inevitable competition reaction from the hydrogen evolution reaction(HER)and consequently decreasing the faradaic efficiency of CO_(2)RR[2,3].Among various reduction products of CO_(2)RR,formate is the most prevalent product with important applications in the energy conversion and chemical *** a host of catalysts that can convert CO_(2)to formate,bismuth(Bi)-based nanomaterials are highly promising electrocatalysts for the conversion of CO_(2)to formate due to their high faradaic efficiency and good ***,the preparation method and catalytic activity of Bi-based nanomaterials still need to be further improved for industrial conversion of the CO_(2)RR.

化学需氧量(COD)是我国评估有机耗氧污染的关键指标,为探究白洋淀湖心区和沼泽区天然水体COD构成组分,通过物理连续分级和三维荧光等方法揭示水体中的耗氧有机物质主要组成、来源和影响因素.结果表明,白洋淀COD主要由类蛋白质和类腐殖质溶解性有机物质贡献(59%~93%),无机物(如Cl^(-)和NO^(-)_(3)等)对COD产生的贡献甚微,可忽略不计;上覆水有机物主要受内生植被降解、沉积物释放[TOC释放通量1.55~2.28 mg·(m^(2)·d)^(-1)]等内源[生物源指数(BIX)>0.8]和人为污染、芦苇台田等陆源的共同影响(1.4<荧光指数(FI)<1.9),沉积物有机质以陆源(芦苇台田)为主.研究水域COD的组分主要受难生化降解有机物质(RDOC)控制,RDOC在天然环境中降解周期较长,重铬酸钾法会在短时间内迅速氧化大部分RDOC,因此高估了水体的有机耗氧污染水平.
