Pyrolytic char/Ν-TiO2 (CTN), pyrolytic char/Ν-F-TiO2 (CTNF) and activated pyrolytic char-TiO2 (ACT) composite catalysts have been successfully prepared by a sol–gel method. TiO2 anatase was the major phase formed in all doped catalysts with a small fraction of brookite phase observed for CTN and ACT. UV–vis diffuse reflectance spectroscopy showed a decrease of band gap energy for all doped CTN and...
The catalytic oxidation of carbon monoxide to carbon dioxide by gold nanoclusters loaded onto cerium oxide supports is an important reaction that has been increasingly tailored for use in hydrogen fuel cells. It has been known that there are simultaneous mechanisms that involve coordination of both the dioxygen and carbon monoxide to the gold, as well as one in which the dioxygen is contributed in...
