Efficient,durable and economic electrocatalysts are crucial for commercializing water electrolysis ***,we report an advanced bifunctional electrocatalyst for alkaline water splitting by growing NiFe-layered double hydroxide(NiFe-LDH)nanosheet arrays on the conductive NiMo-based nanorods deposited on Ni foam to form a three-dimensional(3D)architecture,which exhibits exceptional performances for both hydrogen evolution reaction(HER)and oxygen evolution reaction(OER).In overall water splitting,only the low operation voltages of 1.45/1.61 V are required to reach the current density of 10/500 mA·cm^(-2),and the continuous water splitting at an industrial-level current density of 500 mA·cm^(-2) shows a negligible degradation(1.8%)of the cell voltage over 1000 *** outstanding performance is ascribed to the synergism of the HER-active NiMo-based nanorods and the OER-active NiFe-LDH nanosheet arrays of the hybridized 3D ***,the dense NiFe-LDH nanosheet arrays enhance the local pH on cathode by retarding OH-diffusion and enlarge the electrochemically active surface area on anode,while the conductive NiMo-based nanorods on Ni foam much decrease the charge-transfer resistances of both *** study provides an efficient strategy to explore advanced bifunctional electrocatalysts for overall water splitting by rationally hybridizing HER-and OER-active components.

为完善增程式电动汽车(Extended range electric vehicle,EREV)全生命周期环境影响和经济效益评价研究,对EREV、纯电动汽车(Battery electric vehicle,BEV)和内燃机汽车(Internal combustion engine vehicle,ICEV)进行了对比分析.基于生命周期评价理论和生命周期成本分析方法,构建了车辆生命周期资源消耗、能源消耗、环境影响和成本评价模型,针对不同汽车各阶段材料消耗、能源消耗和环境排放三大特性,识别EREV、BEV和ICEV的环境负荷差异,并从初始购置成本、使用维护成本和报废回收成本3个方面评价了EREV、BEV和ICEV的生命周期成本差异.综合碳排放特性和经济属性,进一步提出减碳经济性评价指标,科学评价EREV和BEV的环境效益和减碳经济性,并讨论了不同电力结构下EREV、BEV和ICEV的生命周期温室气体排放情况和减碳经济性变化.对增程式电动汽车进行全生命周期内综合评价研究,进一步明确EREV在多种能源类型汽车技术路线中的环境效益和减碳经济性.结果表明,相比于ICEV,BEV和EREV在运行使用阶段和全生命周期具有降低化石能源消耗和碳排放的优势,但BEV在原材料获取和制造装配阶段表现出较高的碳排放和矿产资源消耗,EREV在生命周期具有较高的矿产资源消耗. EREV的减碳成本低于BEV,减碳经济性较好.电力结构的优化有助于EREV和BEV减碳经济性的提高.
