2013/10/13
Preyssler acid H14[NaP5W30O110] was used as reducing agent and stabilizer for the synthesis of gold nanoparticles by photolysis of Au(III)/Preyssler acid/propan-2-ol solution. Preyssler acid plays bot...
Identification of Active Sites and Influence of Real Structure of Gold Catalysts in the Selective Hydrogenation of Acrolein to Allyl Alcohol
Gold Catalysts Selective Hydrogenation
2009/7/29
We have successfully employed oxide supported gold
catalysts in the gas-phase hydrogenation of acrolein, the
,-unsaturated aldehyde being most difficult to
hydrogenate at the carbonyl group. The ...
The widely used cyanidation technology is not
applicable to some gold ores due to economic or
technical reasons when the cyanidation gives very low
gold extractions. Despite the fact that the gold ...
