文摘

Rice roll-like Au/SiO2 nanocatalysts were synthesized through one-step inverse miniemulsion-based technique. The rice roll-like Au/SiO2 nanocatalysts embody excellent catalytic activity and good recycling catalytic performance. The rice roll-like Au/SiO2 nanocatalysts display good aqueous dispersibility and pH-dependent, reversible colloidal stability. A formation mechanism of rice roll-like Au/SiO2 nanocatalysts was proposed.
