The characteristic bands of 3000-2850 cm 21 are the mixture vibrations of CH 3 , CH 2 , and CH [33,34]. The characteristic peaks at 1727, 1465, and 1392 cm 21 are assigned to C@O, COH, and CH 3 , CH 2 mixture vibrations [32][33][34].…”

The absorption bank between 1280 and 1070 cm 21 is corresponding to the vibrations of CAO, the rocking and the skeleton vibrations of CH 2 and CH 3 [33,34].…”

“…Polymers are advantageous because in addition to stabilizing and protecting the nanoparticles, they also offer unique possibilities for modifying and adjusting catalytic sites [20][21][22]. The protective polymer not only influences morphologies and particle sizes, but also tremendously influences catalytic activity.…”

“…Shi et al prepared gold nanoparticle by using poly(N, N-dimethylamino ethyl methacryate) as stabilizing and functional agent, which did not need an additional surfactant or functional groups [19]. Shi et al further prepared gold nanoparticles and studied their catalytic activity by using different structure and morphological micelles as stabilizers [20][21][22]. However, the above mentioned metal nanoparticles are only used in certain solutions and discommodious for application [17][18][19][20][21][22].…”
