Metal pollution is one of the significant concerns affecting the environment and the wellbeing of living things. Copper and manganese are the most common metal pollutants with detrimental effects on the health of human beings. Several methods have been proposed and applied for the treatment of indus...
Cu(II) complexation at the water-goethite (alpha-FeOOH) interface was studied by XAFS, potentiometry, and sorption experiments. Thermodynamic data indicate that the initial Cu(II) sorption is not accompanied by release of a H+. As pH is raised, hydrolysis occurs, and a maximum of two H+ ...

-Al2O3and CeO2supports exhibit high activity in reverse water gas shift (RWGS) and preferential oxidation of carbon monoxide (CO-PROX) reactions, respectively. Moreover, the deactivated Cu catalysts after the reactions can be facilely reactivated by exposing to O2-H2O at RT. Results Spontaneous ...
摘要: Investigates the [Cu(OH).TMEDA][sub 2]Cl[sub 2]-catalyzed coupling of arylboronic acids with imidazoles in water. Effect of hydrogen-ion concentration value of liquid medium on the coupling process; Cause of coupling yield decrease; Complexity of the N-arylation system....
molecules on the metal catalysts were active sites for facilitating the effective reduction of CO2to CO. The effect of H2O could also be mirrored by a reversed water-gas shift reaction (WGSR) using Cu/ZnO/Al2O3as catalyst (Supplementary Fig.6a–c) and in situ diffuse reflectance infrared ...
