Urea is one of the most essential reactive nitrogen species in the nitrogen cycle and plays
an indispensable role in the water-energy-food nexus. However, untreated urea or urine …

The excess nitrogen discharge into water bodies has resulted in extensive water pollution
and human health risks, which has become a critical global issue. Moreover, nitrogenous …

The treatment of low-concentration ammonium (eg,< 50 mg L− 1) in highly acidic
wastewaters through traditional biological nitrification, physical separation, or chemical …

Herein, we prepared novel three-dimensional (3D) gear-shaped Co 3 O 4@ C (Co 3 O 4
modified by amorphous carbon) and sheet-like SnO 2/CC (SnO 2 grow on the carbon cloth) …

Converting ammonia in wastewater into harmless nitrogen is a green strategy and
electrochemical advanced oxidation processes (EAOP) based on electron transfer are the …

Heterogeneous photocatalytic (PC) and electrochemical (EC) oxidation of
ammonia/ammonium pollutants in water/wastewater have been thoroughly investigated for …

Ammonia nitrogen pollution is still a global concern, leading to eutrophication of aquatic
ecosystems. Various technologies have been studied and applied for ammonium removal …

Conventional wastewater treatment plants (WWTPs) suffer from high carbon emissions and
are inefficient in removing emerging organic pollutants (EOPs). Consequently, we have …

Inorganic constituents in real wastewater, such as halides and carbonates/bicarbonates,
may have negative effects on the performance of electrochemical systems because of their …

Urea is considered as the potential hydrogen carrier. However, decomposition of urea to
generate hydrogen gas (H 2) is severely constrained by sluggish kinetics and the high over …
