Alkali metal elements are the largest class of toxic elements for SCR catalysts, where their toxicity decreases in the order of Cs2O>Rb2O>K2O>Na2O>Li2O. In addition to alkali metal oxides, alkali metal sulfates
A3NiO2 (A=K, Rb, Cs) are paramagnetic in the whole temperature range investigated. The magnetic susceptibility data have been evaluated by the Curie–Weiss law, where the calculated magnetic moments are as expected for a d9 system (μ=1.73–2.20μB). Negative values of Weiss constants are...
Thermodynamics is a powerful tool for the study of chemical reactions and is intimately related to the atomic and molecular description of the species participating in these reactions. The transformation of energy involved in the reactions depends on the
that the high temperature and pressure, together with the remarkable heat and mass transfer capacity [14] might make the sc-H2O a very feasible reaction environment for effective syntheses of perovskites as its exotic properties are very beneficial to the solid-state reaction between oxides precursor...

The crystal structures of Rb_3NiO_2 and Cs_3NiO_2 were solved and refined by X-ray powder methods. Room temperature 谩-Rb_3NiO_2 (P4_12_12, Z = 4, a = 6.2651(2) A, b = 14.7438(3) A; R_(wp) = 6.30%) and high temperature P-Rb_3NiO_2 (at 523 K P4_2 /mnm, Z =...
The effect of NiAl mixed oxides composition, alkali metal species, and potassium precursors on catalytic activity was investigated. The results show that the catalytic activity of NiAl mixed oxide impregnated by K2CO3 solution is much higher than Na2CO3 and Cs2CO3 modified catalysts; the catalytic ...
Alkali metal/sulfur battery cells, in which the cathodic current collector is a shaped article comprising an aluminum substrate coated with molybdenum, have longer service lives if the molybdenum is overcoated with a layer of molybdenum oxides comprising an outer portion consisting of MoO3. ...
