Abstract
We show, for the first time, the ability to follow the surface chemistry (acid-base equilibrium) of a colloid nanoparticle (AlxOy@SiO2) while simultaneously monitoring the adsorption of a solute molecule (HCOOH) from solution using in situ X-ray photoelectron spectroscopy. Based on the results of the Al 2p and C 1s spectra a mechanism is proposed.
摘要
我们首次展示了使用原位 X 射线光电子能谱同时监测胶体纳米粒子（AlxOy@SiO2）表面化学（酸碱平衡）和溶液中溶质分子（HCOOH）吸附的能力。基于 Al 2p 和 C 1s 谱的结果，提出了一种机理。
