报告摘要：
In this presentation, I will discuss our recent progress toward design of advanced colloidal carbon spheres for energy applications.
We have developed and synthesized various nanoporous carbon spheres (NCSs) (including novel microporous carbon spheres, mesoporous carbon spheres, core shell and yolk shell carbon spheres with hierarchical porous structures) with high monodispersity, defined size and orientation of pores, tunable surface area, and controlled surface properties and structural ordering.Specifically, (i) We developed a strategy to synthesise monodisperse polymer spheres from resorcinol–formaldehyde (RF) resin and carbon “Stöber” spheres.(ii) In addition, modified carbon spheres have been prepared through a bottom up self-assembly by using different functional precursors, or post-synthesis modification method.Furthermore, we have applied this method to produce uniform carbon core–shell spheres with adjustable shell thickness, carbon@metal, carbon@silica, metal@carbon, silica@carbon, or metal oxide@carbon materials. (iii) We also extended the synthesis method of mesoporous silica nanospheres to enable the preparation of ordered mesoporous resorcinol formaldehyde nanospheres with particle size from 80 to 400 nm and mesopores of ~3.5 nm in diameter.(iv) A general strategy was developed for the synthesis of versatile carbon nanospheres impregnated with highly monodispersed metal nanoparticles including (Au, Pt, Rh, Ru, Ag, Pd, Ir, Fe and Cu), testing these metal-loaded carbon particles as catalysts for the hydrogenation of benzaldehyde showed outstanding performance.
Our synthesis strategies provide a new benchmark for fabricating well-defined porous carbonaceous nanospheres with a great promise for energy storage and conversion applications.
