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 …

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 …

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 …

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 …

The effects of Mn2+ precursors on the structure and ozone decomposition activity of
cryptomelane-type manganese oxide (OMS-2) catalysts were investigated under high …

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 …

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 …

Monolithic catalysts with excellent O 3 catalytic decomposition performance were prepared
by in situ loading of Co-doped KMn 8 O 16 on the surface of nickel foam. The triple-layer …

Catalytic ozonation is a promising method for simultaneous removal of NO x and Cl-VOCs,
but needs to clarify their interaction mechanism and the influence of catalyst acidity. In this …

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 …
