Tungsten–humic substances complexation

Carbon Research, 2022
AbstractTungsten (W) is an emerging contaminant whose environmental behaviors remain rather sketchy, narrow, and fragmentary. The mobility and fate of W in the aquatic environments may be influenced by naturally dissolved organic matter (DOM), nevertheless, no studies have addressed how W is bound to DOM.

Spin‐Dependent Generation of Surface‐Bound Radicals Toward Selective and Long‐Lasting Water Purification

Advanced Functional Materials, EarlyView.
This study develops a novel atomic engineering strategy to fine‐tune the spin state of α‐Fe2O3 catalysts toward a medium‐spin state, thereby modulating peroxymonosulfate activation and selectively yielding surface‐bound radicals. Compared with free radicals, surface‐bound radicals exhibit moderated oxidation potential, extended lifespan, surface ...
