Recent research published in the journal Science China Chemistry explores active copper structures in ZnO-Cu interfacial catalysis. Many experiments, including catalyst preparation, structural characterizations, catalytic performance evaluation, and DFT calculations, were performed.
Activated carbon is employed for the adsorption of organic micropollutants (OMPs) from water, typically present in concentrations ranging from ng L1 to g L1. However, the efficacy of OMP removal deteriorates considerably due to competitive adsorption from background dissolved organic matter (DOM), present at substantially higher concentrations in mg L1. Interpreting the characteristics of competitive DOM is crucial in predicting OMP adsorption efficiencies across diverse natural waters.
