图3:通过原位FTIR光谱和原位拉曼光谱展示了Co3O4/Cu1-N-C在电催化还原NO3-过程中的物种变化,以及通过设计拉曼池来探测催化剂表面到电解液体相中NO2-的局部浓度。 图4:通过计算动力学曲线和吸附能力,展示了Co3O4/Cu1-N-C、Cu1-N-C和Co3O4/N-C对NO3-和NO2-的吸附和还原能力,以及通过密度泛函理论(DFT...
射线衍射(XRD)、透射电镜(TEM)、傅里叶变换红PI-(FTIR)光谱、紫外一可见漫反射光谱(UV-VisDRS)等技术对 复合材料的形貌、表面结构、层间微结构、光响应性能进行了研究.结果表明:CN—REC对CuO的形貌具有较好 的调控作用,CuO均匀分散负载于CN.REC的层间和片层表面:CuO和CN.REC通过Si—O—Cu键发生相 ...
FTIR and UV–vis absorption spectra were analyzed to explore the chemical structure of PoPD, PoPD/Cu, and PoPD/Ag polymer films. SEM and AFM analyses revealed distinct morphological differences between the polymer synthesized in the presence of metal salts and the pure polymer. Spectroelectrochemical...
