New Phenols Findings Has Been Reported by Investigators at Fudan University

March 4, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- A new study on Phenols is now available. According to news originating from Shanghai, People's Republic of China, by NewsRx correspondents, research stated, "Gold nanoparticles (Au NPs) were prepared by reducing HAuCl4 with NaBH4. Their average particle sizes could be tuned in the range of 1.7 and 8.2 nm, by adjusting the amount of NaBH4 used during synthesis."

Our news journalists obtained a quote from the research from Fudan University, "The obtained Au NPs (colloids) were then loaded onto a commercial Al2O3 support to prepare Au/Al2O3 catalysts with tunable Au particle sizes. An optimal pH value (5.9) of the Au colloid solution was found to be essential for loading Au NPs onto Al2O3 while avoiding the growth of Au NPs. Au NPs and Au/Al2O3 catalysts were tested in the reduction of p-nitrophenol with NaBH4. Interestingly, the catalytic activity depended on the size of Au NPs, being the highest when the average size was 3.4 nm."

According to the news editors, the research concluded: "Relevant characterization by UV-Vis, TEM, and XRD was conducted."
