Abstract

Attenuated total reflectance infrared spectroscopy is used to monitor nanodiamond surface group transformations in the presence of aqueous IrCl(6)(2-). Electron transfer between the nanoparticle surface and the solution redox species results in oxidation of ∼8.5% of surface alcohol groups, with concomitant formation of unsaturated ketone or quinone-like moieties.

摘要

衰减全反射红外光谱用于监测纳米金刚石表面基团在含有水合三氯化铱(6)(2-)的情况下的转变。纳米颗粒表面和溶液氧化还原物种之间的电子转移导致约 8.5%的表面醇基团被氧化，同时形成不饱和的酮或醌样部分。
