Highly selective production of value-added multicarbon(C^(2+))products via electrochemical CO_(2) reduction reaction(eCO_(2)RR)on polycrystalline copper(Cu)remains ***,the facile surface modification using poly(α-ethyl cyanoacrylate)(PECA)is presented to greatly enhance the C^(2+)selectivity for eCO_(2)RR over polycrystalline Cu,with Faradaic efficiency(FE)towards C^(2+)products increased from30.1%for the Cu electrode to 72.6%for the obtained Cu-PECA electrode at-1.1 V *** hydrogen electrode(RHE).Given the well-determined FEs towards C^(2+)products,the partial current densities for C^(2+)production could be estimated to be-145.4 mA cm~(-2)for the Cu-PECA electrode at-0.9 V *** in a homemade flow ***-situ spectral characterizations and theoretical calculations reveal that PECA featured with electron-accepting-C≡N and-COOR groups decorated onto the Cu electrode could inhibit the adsorption of^(*)H intermediates and stabilize the^(*)CO intermediates,given the redistributed interfacial electron density and the raised energy level of d-band center(E_(d))of Cu active sites,thus facilitating the C-C coupling and then the C^(2+)selective *** study is believed to be guidable to the modification of electrocatalysts and electrodes with polymers to steer the surface adsorption behaviors of reaction intermediates to realize practical eCO_(2)RR towards value-added C^(2+)products with high activity and selectivity.

The electronic configuration of central metal atoms in single-atom catalysts(SACs)is pivotal in electrochemical CO_(2) reduction reaction(eCO_(2)RR).Herein,chalcogen heteroatoms(e.g.,S,Se,and Te)were incorporated into the symmetric nickel-nitrogen-carbon(Ni-N_(4)-C)configuration to obtain Ni-X-N_(3)-C(X:S,Se,and Te)SACs with asymmetric coordination presented for central Ni *** these obtained Ni-X-N_(3)-C(X:S,Se,and Te)SACs,Ni-Se-N_(3)-C exhibited superior eCO_(2)RR activity,with CO selectivity reaching~98% at-0.70 V versus reversible hydrogen electrode(RHE).The Zn-CO_(2) battery integrated with Ni-Se-N_(3)-C as cathode and Zn foil as anode achieved a peak power density of 1.82 mW cm^(-2) and maintained remarkable rechargeable stability over 20 ***-situ spectral investigations and theoretical calculations demonstrated that the chalcogen heteroatoms doped into the Ni-N_(4)-C configuration would break coordination symmetry and trigger charge redistribution,and then regulate the intermediate behaviors and thermodynamic reaction pathways for eCO_(2)***,for Ni-Se-N_(3)-C,the introduced Se atoms could significantly raise the d-band center of central Ni atoms and thus remarkably lower the energy barrier for the rate-determining step of ^(*)COOH formation,contributing to the promising eCO_(2)RR performance for high selectivity CO production by competing with hydrogen evolution reaction.

由芸薹根肿菌(Plasmodiophora brassicae)侵染引起的根肿病是限制油菜生产的主要病害之一,苗期即可发病,目前该病害的主要防治措施有选用抗病品种和使用化学药剂,但农药残留问题日益突出,故提出采用生物防治的策略防控油菜根肿病。笔者采用拌种与苗期灌根的方式研究了芽孢杆菌(Bacillus Bam22)对油菜根肿病的田间防治效果,苗期调查结果表明芽孢杆菌Bam22拌种处理(T1)和芽孢杆菌Bam22+高岭土拌种处理(T2)较清水对照(CK)的发病率降低了3.4%～20%,防效达44%～52%;T1、T2与药剂对照氰霜唑拌种处理(T3)的株高和发病率无明显差异,但防效提高20%～40%。花期调查结果表明T1和T2处理较清水对照(CK)的发病率降低了10%～13%,防效介于28%～51%;T1、T2处理较药剂对照(T3)的发病率降低了6.67%～10%,防治效果提高了5%～22%,单株产量增加了23.97%～34.29%。以上研究结果表明,采用芽孢杆菌Bam22拌种结合苗期灌根,能够有效降低油菜苗期和花期根肿病的发病率,显著降低油菜的产量损失率。芽孢杆菌Bam22对油菜根肿病有较好的控制效果,具有开发成为生物农药的潜力。
