设计分层异质结构作为一种经济且高效的催化剂,以实现水分解的电子和界面工程,是能源存储与转化中的一个有意义的决策.在这项工作中,通过静电纺丝-碳化-电沉积的策略,制备了负载在嵌入Co纳米颗粒的碳纤维上的非晶态NiFeS纳米片(Co-C/NiFeS纳米纤维)催化剂.该催化剂具有优异的析氧反应(OER)活性,在1 mol L^(-1)KOH溶液中,在10 mA cm^(-2)下的过电位为233 mV,Tafel斜率为53.1 mV dec^(-1),同时还具有良好的析氢反应活性.此外,由Co-C/NiFeS纳米纤维作为阳极,商用Pt/C作为阴极构建的碱性Pt/C‖Co-C/NiFeS电解槽在10 mA cm^(-2)下实现1.48 V的低电池电压,优于基准Pt/C‖RuO_(2)电解槽和许多其他报道的电解槽.作为双功能电催化剂,Co-C/NiFeS‖Co-C/NiFeS自身组装的电解槽表现出70小时的长期稳定性,显著优于Pt/C‖RuO_(2)电解槽.该催化剂显著的OER性能得益于Co-C纳米纤维核与非晶NiFeS纳米片鞘组成的明显分层异质结构以及生成的高导电碳纤维基底,这些结构特征赋予该材料丰富的暴露活性位点、良好的导电性和坚固的结构稳定性.因此,这项工作提出了一种简单且有效的方法来制备具有优异电催化性能的非贵金属基催化剂,以用于实际的能量转换和存储.

Org.nic vapors from biomass burning.are a major source of secondary org.nic aerosols(SOAs). Previous smog.chamber studies found that the SOA contributors in biomass-burning.emissions are mainly volatile org.nic compounds(VOCs). While intermediate volatility org.nic compounds(IVOCs) are efficient SOA precursors and contribute a considerable fraction of biomass-burning.emissions, their contribution to SOA formation has not been directly observed. Here, by deploying.a newly-developed oxidation flow reactor to study SOA formation from wood burning. we find that IVOCs can contribute ～70% of the formed SOA, i.e.>2 times more than VOCs. This previously missing.SOA fraction is interpreted to be due to the hig. wall losses of semi-volatile oxidation products of IVOCs in smog.chambers. The finding.in this study reveals that SOA production from biomass burning.is much hig.er than previously thoug.t, and hig.lig.ts the urg.nt need for more research on the IVOCs from biomass burning.and potentially other emission sources.
