Chào mọi người! Mình là thành viên" mới toanh" của diễn đàn. Mong các thành viên giúp mình tìm các hệ phản ứng có mangan,hợp chất của mangan làm xúc tác với! Mình cảm ơn nhiều!
Hi truongthimyduc,
Mangan dùng trong chất làm khô ( xúc tác quá trình tự oxy hóa tạo màng khô của nhựa alkyd trong sơn alkyd)
Ngoài ra còn dùng trong các hệ oxy hóa để loại bỏ NO trong khí thải
Một số ứng dụng khác liên quan đến dùng phức managanse để làm xúc tác tẩy và oxy hóa.

A manganese(IV) complex (MnMeTACN) containing 1,4,7-trimethyl-1,4,7-triazacyclononane (MeTACN), in the presence of polyamines, significantly accelerated the oxidation of ethyl linoleate (EL) emulsions,which can be used as binder of water based alkyd paint.
Dinuclear manganese-based complex Mn2IV(μ-O)3L22 (MnMeTACN) (L = 1,4,7-trimethyl-1,4,7-triazacyclononane).
A series of catalysts of manganese oxide, manganese–cerium and iron–manganese oxide supported on USY (ultra-stable Y zeolite) were studied for the low-temperature selective catalytic reduction (SCR) of NO with ammonia in the presence of excess oxygen. It was found that MnOx/USY have high activity and high selectivity to N2 in the temperature range 80-180 °C. The addition of iron and cerium oxide increased NO conversion significantly although the single-component Fe/USY and Ce/USY catalysts had low activities. Among the catalysts studied in this work, the 14% Ce-6% Mn/USY showed the highest activity. The results showed that this catalyst yielded nearly 100% NO conversion at 180 °C at a space velocity of 30 000 cm3 g-1 h-1. The only product is N2 (with no N2O) below 150 °C. The effects of the concentration of oxygen, NO and NH3 were studied and the steady-state kinetics were also investigated. The reaction order is 1 with respect to NO and zero with respect to NH3 on the 14% Ce-6% Mn/USY catalyst at 150 °C.

Novel bleach and oxidation catalysts, a method of bleaching substrates using these catalysts and bleaching (detergent) compositions containing the catalysts are reported. The catalysts are manganese complexes of formula: [L n Mn m X p] z Y q wherein Mn is manganese or iron or mixtures thereof, which can be in the II, III, IV or V oxidation state or mixtures thereof; n and m are independent integers from 1-4; X represents a co-ordination or bridging species; p is an integer from 0-12; Y is a counter-ion, the type of which is dependent upon the charge z of the complex which can be positive, zero or negative; q=z/[charge Y]; and L is a ligand being a macrocylic organic molecule.
