通过XPS分析吸附后材料表面化学态的变化,进一步支持计算的电子转移理论。 4.研究结果 一、吸附能及结构分析 研究发现,UiO-66的锆空位能显著增强对Pb的吸附能力。计算表明,Pb原子在UiO-66含锆空位表面的吸附能(E_ads)远高于其他离子(如Cu、Zn和Cd),表明其具有优越的亲和性。 吸附能对比: Pb:-2.85 eV Cu:-1.7...
ICP-MS实验表明,UiO-66在混合重金属溶液中对Pb具有大幅优先吸附性,这一趋势与计算预测完全一致。 XPS结果则进一步确认,Pb的吸附过程中产生了Pb-O的化学键,与计算的轨道重叠分析吻合。 5.研究讨论 本文研究结合理论与实验,揭示了UiO-66锆空位对Pb吸附的选择性本质。锆空位通过其不饱和配位环境,提供了高亲和的电子...

Silicon is clearly detected by XPS in all samples, mainly in the form of silica. Si 2p is a doublet with a spin–orbit split of 0.61 eV. Si 2p3/2 of silica is usually found between 103 and 104 eV (Naumkin et al.2012). However, in non-activated and CO2-activated chars, Si 2p3...
Fortunately, the stability of perovskites can be improved by encapsulating them into protective materials such as mesoporous silica [21], [22], metal–organic framework (MOF) [23], [24], and zeolite [25]. Recent publication verified the feasibility of CsPbBr3 @ SiO2 and CsPbBr3: Sn @ SiO2...
