“…S1). In addition, the appearance of another weak band at 2570 cm À1 suggests the existence of eSH in the formed PEI-SH, in agreement with the literature [61]. 1 H NMR was also carried out to confirm the structure of PEI-SH and to quantify the degree of PEI thiolation (Fig.…”

“…The partially thiolated PEI (PEI-SH) was synthesized according to protocols described in the literature [61]. In brief, MTG (108 mL) was added to a freshly prepared PEI aqueous solution (10 mL, 1.0 g), and the mixture was continuously stirred at 60e70 C in a water bath for 24 h to complete the reaction.…”

“…On the basis of the above data, we can conclude that in our system, Au nanoparticles are really immobilized on the surface of thiol-functionalized silica through the strong Au-S bonds. Their existence has been confirmed by many previous works, where the bonding of thiols to gold surfaces was exploited [32][33][34][35][36]. The procedure for preparing Au/SiO 2 catalyst is shown in Scheme 1.…”

Au/SiO 2 catalysts were prepared by self-assembly technique and characterized by EDS, XRD, XPS, AAS and N 2 adsorption/desorption. They were found to be very efficient catalysts for the selective oxidation of cyclohexane with air in the absence of any solvent or promoter. The influences of Au loading, reaction temperature, reaction pressure and reaction time on the catalytic activity were explored in detail. Under suitable reaction conditions, the conversion of cyclohexane and total selectivity of cyclohexanone and cyclohexanol were up to *10 and *92%, respectively.

Hyperbranched poly(amidoamine) conjugated silica (HBPcS) particles were synthesized by grafting poly(amidoamine) dendrimers on multiple-functional hybrid silica (MHS) particles containing three different organosilane functional groups. Due to advantageous combination of dendrimers, with ample and controlled amount of amine groups, and monodisperse and stable MHS particles from simple one-pot synthesis, the HBPcS particles can serve as multifunctional platforms for various applications. The growth of the amine functional groups of the HBPcS particles with the generation number was confirmed by monitoring the amide peaks in IR spectra as well as indirectly by monitoring the amount of the molecules that are bound to the functional groups. As a proof of principle, colorimetric sensors for Cd ions were prepared by employing the HBPcS particles and organic Cd ion sensing molecules. Notably, the sensor particles from HBPcS particles of different generations showed different detection ranges due to the increase in the amount of amine functionalities by grafting processes.
