| 英文摘要 | Carboxymethylated chitosan (CMCts) protected ruthenium nanoparticles (RuNPs) were synthesized by gamma-radiation-induced reduction of metal ions at room temperature. The characteristics of RuNPs/CMCts composites prepared under different experimental conditions have been investigated by means of TEM, XPS and TGA. The results indicated that the average size of RuNPs increases as the concentration of precursor decreases. Narrowly distributed nanocomposites have been obtained when low molecular weight CMCts (LM-CMCts, M-n = 4400 Da) was utilized as stabilizer. The TEM images demonstrated the RuNPs prepared in a wide pH range of 4.5-12.3 can be dispersed uniformly in the alkalic CMCts solution for more than 2 months with the average particle sizes of 1.0-3.0 nm. XPS spectrum confirmed the ruthenium ions have been reduced to metal atoms by irradiation. TGA curves indicated that RuNPs/CMCts composites exhibited good thermal stability at temperature less than 200 degrees C and strong interactions existed between the metal nanoparticles and stabilizer molecules.
