Controllable synthesis and catalysis application of hierarchical PS/Au core–shell nanocomposites

Long chain ionic liquid-assisted synthesis of PS/Pd beads and hierarchical porous Pd–SiO2

“…These SEM images are similar to the images of PS spheres covered with dense and uniform Au NPs. 31 Fig . 3 further shows TEM images of PS/C 16 mimCl/Pd(x) bead with different coverage.…”

Synthesis of IrO2 decorated core–shell PS@PPyNH2 microspheres for bio-interface application

“…The synthesis of core-shell (core@shell) microspheres has attracted considerable attention recently, due to their great potential in a variety of applications, including drug release, photocatalysis, and electrocatalysis [1][2][3][4][5]. In general, the most popular core components are either SiO 2 or polystyrene (PS) microspheres, whereas the shell constituent can comprise different polymers or inorganic materials [6][7][8][9]. Among the various combinations of core@shell microspheres, the use of polypyrrole (PPy) is of particular interest, because the PPy is a well-established conductive polymer, owing to its impressive electrical, electrochemical, and optical properties, as well as its biocompatibility and environmental stability [10][11][12][13].…”

A protector-free one-pot strategy to synthesize highly dispersed Pd hydrogenation catalysts in a broad loading range on polystyrene

“…However, note that this method could only be feasible in a low and narrow loading range of metal due to the limited surface area of the support. 13,14 In addition, the randomness of impregnation or deposition processes always leads to uneven distribution of metal precursors on the supports and consequently fails to prepare metal particles in the desired narrow size range. 15,16 Based on this situation, pursuing a feasible and ideal system to overcome the drawbacks of the above mentioned traditional preparation methods is still an open topic for both the design and application of precious metal catalysts.…”
