2025年3月15日 · A novel binary metal nanoparticle catalyst; iron copper phosphate nanoparticles (FeCuP), was synthesized via a hydrothermal route under mild conditions without surfactants or post-treatment uses. Three variants of the catalyst, FeCuP1, FeCuP2, and FeCuP3, were prepared using different urea amounts.

2020年9月1日 · Here we report a facile two-step approach to fabricate trimetallic Fe/Co/Cu-based phosphides embedded onto nitrogen-doped carbon-graphene (FeCoCuP@NC). The FeCoCuP@NC exhibits excellent electrocatalytic hydrogen evolution reaction (HER) performance with low overpotential and durable long-term stability in both acidic and alkaline conditions.

xps，即x射线光电子能谱。 原理简单来说是将X射线光子入射到样品上，将样品的光电子和俄歇电子激发出来。 在阅读文献中，经常可以看到XPS图谱，用来分析样品表面元素的价态变化、成分和分子结构 下面以一个图来举例…
