8263 1244 Au-MCM-41 hybrids 50 nm TEM Figure 1. Synthesis and characterization of the Au-mesoporous silica hybrids: (a) Schematic description of the different synthesis stages including (i) the synthesis of the Au NPs with the aid of THPC [59,62]; (ii) the synthesis of the MCM-41 ordered mesoporous spheres and the amino-grafting step with APTES [49,65,66]; (iii) the gold seeding attachment by electrostatic attraction; (b–c) HAADF-STEM images of the individual Au NPs; (d–e) TEM images at different magnifications of the mesoporous silica supports showing the ordered organization of the mesochannels; (f–g) TEM and STEM images displaying the correct gold seeding process via electrostatic attraction and the formation of the Au-silica hybrid nanoparticles.
