The aim of the study was the synthesis of multifunctional TiO2-ZnO oxide systems with desired antibacterial and photocatalytic activity. It was investigated how the TiO2:ZnO molar ratio and the time of hydrothermal treatment affected the physicochemi

A novel TiO2-SiO2/Bi2O3 oxide material (TSB) was prepared for a first time via the sol-gel method. The synthesis was performed using titanium(IV) isopropoxide, tetraethoxysilane and bismuth nitrate pentahydrate as oxide precursors, ammonia as hydroly

Using the by-product biopolymer lignin and nanoparticles of magnetite, well-known for its nontoxicity and magnetic properties, novel nanomagnetite–lignin hybrid materials were synthesized. In the first step, magnetite was produced via a co-precipit

A study was made of the adsorption of three selected food dyes (C.I. Food Black 1, C.I. Food Brown 3 and C.I. Food Green 4) on the surface of an inorganic, synthetic TiO2-SiO2 support of anatase form. This produces new hybrid pigments having desirabl

A new method of synthesis of advanced, functional hybrid materials obtained from TiO2 or TiO2-SiO2 and lignin has been proposed. The resulting hybrids exhibited specific physicochemical and structural properties, which were determined by a number of
