论文摘要
我们通过放牧的含量传输小型和广角X射线散射（GTSAXS和GTSAXS和GTWAXS），X射线荧光（XRF）和2级的表面光学反射率（2DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDS），研究了电化学制造的PD纳米线的结构演化。这表明了电沉积和氢进化反应（她）如何在PD电depositon期间竞争并相互作用。在纳米线的自下而上生长期间，我们表明$β$ - 相PD氢化物形成。然后暂停电沉积，然后导致相位从$β$ - $α$ - 相PD氢化物的过渡。此外，我们发现谷物合并后来阻碍了氢在PD单位细胞中的掺入。 GTSAXS和2D-SOR提供了有关PD占用孔的体积分数的互补信息，而XRF则用于监视PD电沉积的量。
We investigated the structural evolution of electrochemically fabricated Pd nanowires $\textit{in situ}$ by means of grazing-incidence transmission small- and wide-angle x-ray scattering (GTSAXS and GTWAXS), x-ray fluorescence (XRF) and 2-dimensional surface optical reflectance (2D-SOR). This shows how electrodeposition and the hydrogen evolution reaction (HER) compete and interact during Pd electrodepositon. During the bottom-up growth of the nanowires, we show that $β$-phase Pd hydride is formed. Suspending the electrodeposition then leads to a phase transition from $β$- to $α$-phase Pd hydride. Additionally, we find that grain coalescence later hinders the incorporation of hydrogen in the Pd unit cell. GTSAXS and 2D-SOR provide complementary information on the volume fraction of the pores occupied by Pd, while XRF was used to monitor the amount of Pd electrodeposited.
