PDIN与PDINO表明，具有高电子亲和力的π离域平面结构在开发高性能有机电子传输层材料中优势巨大。事实上，这项工作也是首次报道了对厚度不敏感的小分子型电子传输层材料。相关研究成果最终发表在《Energy & Environmental Science》上。 图4：PDINN合成路线与性能分析

2022年4月4日 · With the support of in situ (EXAFS and IR) and ex situ (XPS, Raman) spectroscopic techniques, the optimum presence of the Pd–In–O interface has been identified as a crucial parameter for enhancing eCO 2 RR toward CO in a reducing atmosphere.

Formation of PdIn intermetallic nanoparticles supported on α-Al2O3 was investigated by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and hydrogen temperature-programmed desorption (H2-TPD) methods. The metals were loaded as ...

2023年9月8日 · Reduction of the initial PdIn/Al 2 O 3 catalyst (after prolonged storage in air) in H 2 at 500 °C leads to the formation of PdIn intermetallic nanoparticles. XPS data show the presence of only Pd IMC and domination of In IMC (with a minor admixture of In oxide) on the catalyst’s surface.

在原位（EXAFS 和 IR）和非原位（XPS、拉曼）光谱技术的支持下，Pd-In-O 界面的最佳存在已被确定为增强 eCO 2 RR 对 CO 还原反应的关键参数气氛。 据报道，eCO 2 RR 持续时间的影响通过将产品选择性从 H 2切换为影响整体性能（来自水还原）到氧化物衍生合金表面上的CO（来自 eCO 2 RR）。 这项工作还通过使用气体扩散电极 (GDE) 并在流通池配置中优化其工艺参数，成功地成倍提高了电流密度。

2023年7月3日 · Using the cathode interlayer PDIN: PFN-Br (0.9:0.1, in wt.%) in the devices can reduce the electrode work function, suppress the dark current leakage, and improve charge extractions, leading to enhanced short circuit current density and fill factor.

UPS测试结果中，与单一PDIN或者PFN-Br阴极界面层相比，混合阴极界面能最有效地将Ag的功函数降低；同时，XPS测试结果中也是使用混合阴极界面的器件Ag表面结合能降低最明显。 为了进一步分析PDIN和PFN-Br中的N和Br的结合能变化，使用XPS对三组不同界面进行了表征，最后发现N和Br的结合能均发生减少。 图3.（a）不同阴极界面层覆盖的Ag电极的UPS谱图；（b）Ag 3d在Ag、PFN-Br/Ag、PDIN/Ag和PDIN: PFN-Br/Ag表面的XPS谱图；（c）Br 3d在PFN-Br、PFN …
