Here we demonstrate the in situ formation of ultra-small gold nanoparticles (<2 nm) finely dispersed on a binary solid carrier, i.e. a mesoporous SiO2 coated graphene oxide (GO) nanosheet. The as-synthesized Au-SiO2-GO composite has shown high catalytic activity and reusability for chemical reactions under mild conditions.
在此,我们展示了超小金纳米颗粒(<2纳米)在二元固体载体上的原位形成,该载体为介孔二氧化硅包覆的氧化石墨烯(GO)纳米片。所合成的金-二氧化硅-氧化石墨烯复合材料在温和条件下对化学反应表现出高催化活性和可重复使用性。
