Enhanced Electron‐Capturing by Single‐Atomic Iron on Pyridinic N‐Deficient Carbon Drives Self‐Oxidative Degradation of Pollutants

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Pyrolysis of FeOx/g‐C3N4 and ZIF‐8 is performed to introduce Fe single atom and pyridinic nitrogen vacancies onto N‐doped carbon. This modification enables the materials to efficiently extract electrons from ciprofloxacin (CIP) and activate dissolved oxygen. 100% of CIP was degraded within 1 min without adding any oxidant.

Dissociation behaviour of humic acids

open access: yes, 2015
Humic acids are substances of natural origin and form the finest part of humic substances. They are formed by biochemical transformations of organic residues (mainly plants).

The Role of Concentration and Solvent Character in the Molecular Organization of Humic Acids

open access: yesMolecules, 2016
The molecular organization of humic acids in different aqueous solutions was studied over a wide concentration range (0.01–10 g·dm−3). Solutions of humic acids were prepared in three different media: NaOH, NaCl, and NaOH neutralized by HCl after ...
