An anomalously large difference was found in the energies of the 2p, 3s, and 3p lines in the X-ray photoelectron spectra for all metal ions in complexes [Fe2MO(O2CCH3)6(H2O)3](H2O)3 and [Fe2MO(O2CCCl3)6(H2O)3](H2O)3(M = Co, Ni). The observed line shifts were explained in the framework of an electrostatic model considering the change in the interaction energy of the electrons of metal atoms and the charge distribution of the peripheral fragments of the complexes. © 2016 Springer Science+Business Media New York

Sulfonation of mesoporous organosilicas with diethylxylene bridging groups using chlorosulfonic acid gave mesoporous silicas with arylsulfonic acid bridging groups. TPD-MS was used to confirm the structure and characterize the thermal stability of the organic groups of the starting and sulfonated samples. The catalytic activity of mesoporous silicas with arylsulfonic acid bridging groups in the synthesis of ethyl tert-butyl ether is higher than for model samples (MCM-41 mesoporous molecular sieves and silica gel with anchored alkylsulfonic acid groups as well as SiO2/Nafion nanocomposite) and is similar to the activity of industrial catalysts such as Amberlyst-15. © 2014 Springer Science+Business Media New York.

The use of CTMABr as a template along with prior treatment of samples of WOx{dot operator}ZrO2 with phosphoric acid yields heat-stable mesoporous phosphated tungstate-containing materials. The selectivity of these materials relative to acrolein in the dehydration of glycerin depends on the content of WOx in the samples, while the product yield depends on the heat treatment conditions. © 2014 Springer Science+Business Media New York.
