Efficient oxygen electrocatalysts are the key elements of numerous energy storage and conversion devices, including fuel cells and metal-air batteries. In order to realize their practical applications, highly efficient and inexpensive non-noble metal-based oxygen electrocatalysts are urgently required. Herein, we report a novel iron-chelated urea-formaldehyde resin hydrogel for the synthesis of Fe-N-C electrocatalysts. This novel hydrogel is prepared using a new instantaneous （20 s） one-step scalable strategy, which theoretically ensures the atomic-level dispersion of Fe ions in the urea-formaldehyde resin, guaranteeing the microstructural homogeneity of the electrocatalyst. Consequentl~ the prepared electrocatalyst exhibits higher catalytic activity and durability in the oxygen reduction （ORR） and evolution （OER） reactions than the commercial Pt/C catalyst. Furthermore, the above catalyst also shows a much better performance in rechargeable Zn-air batteries, including higher power density and better cycling stability. The developed synthetic approach opens up new avenues toward the development of sustainable active electrocatalysts for electrochemical energy devices.

The development of an electrocatalyst based on abundant elements for the oxygen evolution reaction （OER） is important for water splitting associated with renewable energy sources. In this study, we develop an interconnected Ni（Fe）OxHy nanosheet array on a stainless steel mesh （SSNNi） as an integrated OER electrode, without using any polymer binder. Benefiting from the well- defined three-dimensional （3D） architecture with highly exposed surface area, intimate contact between the active species and conductive substrate improved electron and mass transport capacity, facilitated electrolyte penetration, and improved mechanical stability. The SSNNi electrode also has excellent OER performance, including low overpotential, a small Tafel slope, and long-term durability in the alkaline electrolyte, making it one of the most promising OER electrodes developed.

基于福建省林改监测数据,使用OLS最小二乘法和Tobit方法进行估计,实证分析非农就业对农户经济林经营投入及收入的影响效应和组群差异,并对森林保险和林业补贴政策进行调节效应检验。结果表明:非农就业对农户经济林经营的投入与收入均产生抑制作用;本地非农就业与外出务工对农户经济林经营的投入与收入均产生抑制作用;非农就业对家庭居住地距离城市20 km以内的农户经济林经营投入产生显著的抑制作用,而对家庭居住地距离城市20 km以外的农户经济林经营行为的影响不大;非农就业对闽西北林区的农户经济林经营的投入与收入均产生显著的抑制作用,而对闽东南的农户经济林经营的投入与收入影响都不大;非农就业对有森林保险或森林补贴的农户经济林经营的收入具有显著的促进效应,但对其投入的影响效应不显著。因此,应该根据不同就业类型的农户制定出有针对性的差异化的帮扶政策,引导农户经济林经营;根据不同地区特点采取差异化管理手段;完善森林保险、森林补贴政策,设计“重点倾斜性”的补贴政策。同时,积极引入技术人才,加强推广农技服务,完善林业生产外包服务制度。

氢能作为一种潜在的能源载体,有望取代化石燃料,解决当今社会的能源需求和环境问题.质子交换膜电解水(PEMWE)技术因其工作电流密度大、氢气纯度高和系统响应迅速等优点,能够有效地弥补可再生能源波动性等缺点,被认为是一种利用可再生能源制氢的可持续手段.但其阳极氧析出反应(OER)为四电子/质子转移过程,反应动力学缓慢,同时强氧化性和强酸性环境会对阳极催化剂的产生腐蚀,导致稳定性差,因此亟需开发高效且稳定的催化剂.研究发现,无定型氧化铱材料中的特殊缺陷结构可显著提升其催化酸性OER的活性,但该结构也会加速反应过程中铱的溶解,导致催化剂稳定性降低,严重限制了其实际应用.本文采用高价金属掺杂的策略,利用高价金属元素与氧的强成键作用,对无定型氧化铱的整体结构及活性位点起到优化且稳定的作用.首先,采用改性的亚当斯熔融法制备了金属钽掺杂的无定型氧化铱:350-Ta@IrO_(x),400-Ta@IrO_(x),450-Ta@IrO_(x)(350,400和450代表样品分别在350,400和450℃烧结),并用于催化酸性OER;作为对比,制备了无掺杂的无定型氧化铱:350-IrO_(x),400-IrO_(x)和450-IrO_(x).然后,通过扫描电子显微镜、透射电子显微镜(TEM)和X射线衍射等表征技术考察了材料的宏观形貌及微观结构.结果表明,掺杂后的350-Ta@IrO_(x)材料表面具有丰富的氧空位贡献的活性位点,且表现出多晶的超小纳米颗粒形貌.电化学测试结果表明,350-Ta@IrO_(x)具有较好的酸性OER活性,在10 mA cm-2的电流密度下,过电势仅为223 mV,在1.55 V ***的电位下质量活性为1207.4 A gIr-1,是商业二氧化铱的147.7倍.且该催化剂的稳定性比未掺杂Ta样品及商业二氧化铱有明显提升,在0.5 mol L^(-1)硫酸溶液中反应500 h后电位未发生明显变化.密度泛函理论计算结果表明,Ta掺杂与构建缺陷有利于OER决速步中水分子的亲核进攻,从而提升催化活性并降低反应过电势.为进一步研究材料在酸性OER工作状态下具有较好稳定性的原因,采用TEM和X射线光电子能谱等对反应前后的材料进行表征.结果表明,350-Ta@IrO_(x)在反应前后结构保持稳定,Ir溶解速率较未掺杂样品明显降低,证明了Ta掺杂大大提升了无定型氧化铱材料的稳定性.综上,本文发展了制备高价金属掺杂氧化铱的改性亚当斯熔融法,利用高价金属元素与氧的强成键作用,调控了铱活性位点的电子结构,同时提升了氧化铱类材料在酸性氧析出反应中的活性与稳定性,简化了此类材料的合成方式,为进一步降低质子交换膜电解水器件阳极催化剂的成本和提高其催化活性提供了新思路.
