Catalytic ozonation is an environmentally friendly technology for the removal of gaseous NH
3 due to high NH 3 conversion and high N 2 selectivity at ambient temperature. However …

Two kinds of cryptomelane-type manganese oxide (OMS-2-Ac and OMS-2-SO 4) catalysts
were prepared with MnAc 2· 4H 2 O and MnSO 4 as precursors, respectively, and were …

Eliminating ammonia (NH 3) from high-humidity exhaust gases by catalytic oxidation is a
great challenge, especially at low temperatures. Herein, Cu and N co-doped cryptomelane …

Catalytic ozonation based on heterogeneous metal oxides is a promising approach to
removing ammonia as gaseous nitrogen from water. Herein, MgO/Co 3 O 4/CeO 2 was …

It is highly concerned to explore heterogeneous catalysts of metal oxides to remove NH 4+-
N in the wastewater, in which NH 4+-N can be greatly oxidized as gaseous nitrogen in the …

As one of the most important water pollutants, ammonia nitrogen emissions have increased
year by year, which has attracted people's attention. Catalytic ozonation technology, which …

Large amounts of water containing-ammonium nitrogen (NH 4+-N) have attracted increasing
attention. Catalytic ozonation technology, involving the generation of hydroxyl radical (· OH) …

Abstract Ammonia nitrogen (NH 4+-N), which exists in the dominant form of ammonium ion
(NH 4+) under the pH of 6.5–8.5, is one of the regular indexes and the most important …

In this paper, CO atmosphere reduced cobalt manganate (CoMn2O4/CO), prepared by a
hydrothermal method, was successfully utilized in catalytic ozonation for NOx removal …

In this work, CTAB-NiO catalyst was prepared by solid-state method and employed for
oxidizing ammonia (NH 4+) in aqueous solution by catalytic ozonation. In order to obtain …
