In the last few years, gold catalysts have generated a great amount of interest. This has been the result of two main findings: gold is the most active catalyst for ethyne hydrochlorination, and it is also effective for ...

A novel method to obtain catalytic bio-nanocomposites based on chitosan containing different amounts of gold nanoparticles generated in situ is reported. The formation of gold nanoparticles takes place in solid phase ...

Au/Nb2O5 and Au/CeO2 catalysts were studied for the selective hydrogenation of crotonaldehyde, both in liquid (batch reactor, 4 atm, 60 °C, solvent: isopropanol) and in gas (flow microreactor, 120 °C, atmospheric pressure) ...

The experimental data of CO oxidation over the series of 2 wt.% Au/Ce1-xZrxO2 (x=0, 0.25, 0.5, 0.75, 1) catalyst were analyzed using a variation of the Temperature Scanning Method with the aim of catalyst's composition ...

The nature of gold species in Au/CeXZr1-XO2 catalysts was successfully investigated using the visible and near infrared photoacoustic spectroscopy and Fourier transform infrared spectroscopy of adsorbed carbon monoxide. ...

The diesel soot combustion was studied using catalysts prepared by impregnation with cesium nitrate and/or gold on zirconium oxide (ZrO2), hydrated zirconium oxide and silica (SiO2). Catalysts were characterized by ...
