Radical‐initiated support: Xanthates were used as chemical reagents for the sidewall covalent functionalization of carbon nanotubes (see figure). The best grafting yields were obtained with stoichiometric ratios of xanthate and the radical initiator lauroyl peroxide. One grafted function was used as a tether for bimetallic cluster compounds, which were converted into very small (1–2 nm) supported nanoparticles
自由基引发的载体:黄原酸酯用作化学试剂,用于碳纳米管的侧壁共价官能化(见图)。用黄原酸酯和自由基引发剂月桂酰过氧化物的化学计量比可获得最佳的接枝产率。一种接枝功能被用作双金属簇化合物的束缚物,在加热时它们会转化为非常小的(1-2 nm)负载的纳米颗粒。
