文摘
- •
Ag/TiO2 nanocomposites with Ag clusters under 2 nm are synthesized through a silver mirror reaction in toluene.
- •
The silver mirror reaction refers to the reduction of silver-dodecylamine complexes by acetaldehyde in toluene.
- •
The Ag/TiO2 nanocomposites show a good ability of resistant against poisoning by the product in reduction of 4-NP.
- •
TOFs of Ag/TiO2 nanocomposites obtained in this work are the highest among Ag based catalysts previously reported.
