Catalyst–support interaction plays a crucial role in improving the catalytic activity of oxygen evolution reaction(OER).Here we modulate the catalyst–support interaction in polyaniline-supported Ni_(3)Fe oxide(Ni_(3)Fe oxide/PANI)with a robust hetero-interface,which significantly improves oxygen evolution activities with an overpotential of 270 mV at 10 mA cm^(-2)and specific activity of 2.08 mA cm_(ECSA)^(-2)at overpotential of 300 mV,3.84-fold that of Ni_(3)Fe *** is revealed that the catalyst–support interaction between Ni_(3)Fe oxide and PANI support enhances the Ni–O covalency via the interfacial Ni–N bond,thus promoting the charge and mass transfer on Ni_(3)Fe *** the excellent activity and stability,rechargeable Zn-air batteries with optimum Ni_(3)Fe oxide/PANI are assembled,delivering a low charge voltage of 1.95 V to cycle for 400 h at 10 mA cm^(-2).The regulation of the effect of catalyst–support interaction on catalytic activity provides new possibilities for the future design of highly efficient OER catalysts.

Although poly(lactic acid)(PLA)is a good environmentally-friendly bio-degradable polymer which is used to substitute traditional petrochemical-based polymer packaging films,the barrier properties of PLA films are still insufficient for high-barrier packaging *** this study,oxygen scavenger hydroxyl-terminated polybutadiene(HTPB)and cobalt salt catalyst were incorporated into the PLA/poly(butylene adipate-co-terephthalate)(PLA/PBAT),followed by melting extrusion and three-layer co-extrusion blown film process to prepare the composite *** oxygen permeability coefficient of the composite film combined with 6 wt%oxygen scavenger and 0.4 wt%catalyst was decreased significantly from 377.00 cc·mil·m^(-2)·day^(-1)·0.1 MPa^(-1) to 0.98 cc·mil·m^(-2)·day^(-1)·0.1 MPa^(-1),showing a remarkable enhancement of 384.69 times compared with the PLA/PBAT composite ***,the degradation behavior of the composite film was also accelerated,exhibiting a mass loss of nearly 60%of the original mass after seven days of degradation in an alkaline environment,whereas PLA/PBAT composite film only showed a mass loss of 32%.This work has successfully prepared PLA/PBAT composite films with simultaneously improved oxygen barrier property and degradation behavior,which has great potential for high-demanding green chemistry packaging industries,including food,agricultural,and military packaging.

随着社会的不断进步,食品工业得到快速发展,随之食品安全问题也层出不穷。由于合成抗氧化剂价格较低且对食品有较好的防腐保鲜作用,常被一些食品生产商过量添加在食品中,严重危及人们身心健康。因而,对于食品中合成抗氧化剂的检测研究是十分必要的。丁基羟基茴香醚(BHA)和叔丁基对苯二酚(TBHQ)是两种常见的合成抗氧化剂。实验上,利用共聚焦显微拉曼光谱仪分别对BHA和TBHQ进行拉曼光谱检测,获得样品的拉曼散射谱。理论上,应用密度泛函理论DFT(B3LYP)的三参数混合方法及6-31G(d,p)基组对其进行空间结构优化并计算其拉曼光谱,给出了光谱强度图。将理论结果与实验结果进行对比发现,在50~4 000cm^(-1)范围内BHA及TBHQ分子拉曼特征明显且拉曼活性较强,其振动频率在实验上和理论上显示出较好的一致性。另外,给出了BHA和TBHQ分子的红外活性、拉曼活性以及各频率谱线对应的振动模式归属。结果表明,BHA和TBHQ分子的拉曼频移表征物质的特征结构,可以作为鉴定和识别的检测依据。该研究报道了抗氧化剂BHA和TBHQ的拉曼光谱,并对其理论机制进行分析,为拉曼光谱技术应用于食品添加剂研究领域提供了理论和实验依据。
