TL;DR: Analysis of adsorption experiments, structure and surface analysis, and spectroscopic analysis indicated that initially phosphate preferentially bound to two Fe-OH2(1/2+) groups to form a binuclear bidentate surface complex without OH(-) release, with smaller size ferrihydrites exchanging more Fe- OH2( 1/2%) per mass.

TL;DR: The mechanism of improving the photocatalytic H2-evolution activity was further confirmed by time-resolved fluorescence, electron paramagnetic resonance, transient photocurrent response and electrochemical impedance spectroscopy.

TL;DR: In this article, the effect of variable substructures on the sorption sites of hexagonal birnessites with various Mn average oxidation states (AOS) was investigated, and the results showed that a decrease in Mn AOS of a given birnessite decreased considerably the capacity for heavy metals, despite the fact that the specific surface area increased almost linearly.

TL;DR: In this article, the adsorption-desorption behavior of phosphate on ferrihydrite, goethite, and hematite and underlying mechanisms were comparatively investigated with batch kinetics, solution equilibrium, and mineral characterization.

TL;DR: In this paper, the authors developed an easy and reliable approach to prepare crystalline graphitic carbon nitride (g-C3N4) heterojunction by using preheated melamine as precursor and molten salts as the liquid reaction media.
