Abstract

The TEM images of core–shell Au@SiO2@Pdop (a, b) and Au@void@C(c, d) in the ratio of ethanol and water(10:1). Figure S2. The SEM imagines of Au(a,b), Au@SiO2@Pdop(c,d), Au@void@C(e,f). Figure S3. ln (C/C0) versus time for the reduction of MB. Figure S4. The SEM imagines of Fe3O4@SiO2@Pdop(a,b), Fe3O4@void@C(c,d), CNTs@Fe3O4@SiO2@Pdop(e,f), CNTs@Fe3O4@void@C(g,h), α-Fe2O3@SiO2@Pdop(I,j), α-Fe2O3@void@C(k,l), Ag@SiO2@Pdop(m,n), Ag@void@C(o,p) at different magnetification.
