Abstract: Ultrasensitively selective detection of trace polycyclic aromatic hydrocarbons (PAHs) like phenanthrene (PHE) is critical but remains challenging. Herein, atomically dispersed Zn sites on g‐C3N4 nanosheets (sZn‐CN) are constructed by thermal polymerization of a Zn–cyanuric acid–melamine… read more here.

Abstract: Introducing heteroatoms into atomically dispersed Fe-N4 sites with symmetric electron distribution can adjust the imperfect oxygenated adsorption-activation and promote oxygen reduction reaction (ORR) activity. However, the relevant design synthesis and deeply understanding the electrocatalytic mechanism… read more here.

Abstract: The heterogeneous electro-Fenton (hetero-e-Fenton)-coupled electrocatalytic oxygen reduction reaction (ORR) is regarded as a promising strategy for ·OH production by simultaneously driving two-electron ORR toward H2O2 and stepped activating the as-generated H2O2 to ·OH. However, the… read more here.
