Effect of mechanical−chemical modification on adsorption of beryllium by calcite

Stabilizing oxygen-deficient Mn sites active in seawater oxidation

“…6e). 47 These carbonates were found to be irreversibly adsorbed on the active sites during seawater electrolysis. However, owing to the high surface area of the substrate and the nanostructures, the catalyst maintained substantial geometric activity even when a fraction of the active sites was blocked by these insoluble precipitates.…”
