“…Perovskite structure was formed after calcination of freshly-prepared precipitate at 500°C, which was significantly lower than the previous study [8]. The homogeneous formation of LST resulted from co-precipitation of titanium peroxohydroxide formed in basic solution and cations of strontium and lanthanum in the nitrate solutions [9]. However, the powder revealed the change of crystal structure after calcination of precipitate after ageing under an air atmosphere for several days.…”

Lanthanum-doped strontium titanate powder, La 0.05 Sr 0.95 TiO 3+δ , was fabricated by peroxidebased route and calcination of freshly prepared precipitate and precipitate after ageing was carried out. The starting titanium precursor was titanium nitride, which underwent the reaction to form titanium peroxohydroxide and then compound containing strontium and lanthanum. A perovskite structure of strontium titanate with 5 mol-% doped lanthanum was obtained after calcination of the freshly-prepared precipitate at 500°C. However, the ageing powder revealed the presence of the second phase of strontium carbonate after calcination at the same condition. Thermogravimetric results showed that the decomposition of ammonia promoted a reaction to form the pure phase of ceramic oxide only in the freshly calcined sample.

“…Nickel hydroxide and LDH can be prepared using various methods, for instance: high-temperature two-stage synthesis [29], electrochemically in a slit-diaphragm electrolyzer [30], decomposition method [31], precipitation at constant рН [32,33], high-temperature interaction of solution with nickel-foam matrix [38]. The most common and simple is chemical precipitation at various temperatures.…”

“…Такое замещение создает избыточный заряд, который компенсируется анионами, располагающимися между слоями Me-O-H вместе с водой [1].В литературе также описываются СДГ, в которых часть двухвалентных катионов замещена на четырехвалентные: Ti 4+ [2,3], Zr 4+ [4],V 4+ [5]. Благодаря изменчивости состава СДГ широко применяются в качестве катализаторов, носителей [6,7], прекурсоров оксидных катализаторов и сорбентов [8][9][10], и др.…”

The molybdate intercalated layered double hydroxides can be potentially applied as catalysts for organic synthesis a nd oxidation. According to literature they are most commonly prepared using multi-stage methods such as anion-exchange and rehydration of calcinated LDH precursor. Aim of the work was to study a possibility of one-stage synthesis of molybdate-intercalated Ni-Ti LDH. To achieve the set-out aim, a sample of molybdate-intercalated Ni-Ti LDH has been prepared using one-step coprecipitation at high supersaturation at room temperature synthesis method: drop-wise introduction of nickel and titanium salts solution into solution of sodium hydroxide and ammonium heptamolybdate. The prepared sample was characterized by SEM, XRD, FTIR, TG-DTA and EDX. Hydrotalcite-like structure has been confirmed by results of XRD, FTIR and TG. The results of SEM have showed that sample morphology is constituted by spherical agglomerates. According to XRD results the prepared sample has rather low crystalinity. The results of TG-DTA showed that thermal decomposition of the sample occurs into two stages: 1) 90-180 o C accompanied by an endothermic event and associated with loss of adsorbed and interlayer water; 2) 280-340 o C accompanied by an endothermic event and associated with dehydroxilation brucite-like layered, transformation of LDH into LDO and, possibly, transformations in Ni-Ti-MoO system. Results of FTIR have confirmed successive intercalation of molybdate anion into interlayer space of Ni-Ti LDH. The results of FTIR also indicate presence of polymobdate forms. The results of EDX analysis showed molar ratio of Ni:Ti:Мо=1:0,19:0,22. The acquired results show the possibility of one-stage synthesis of molybdate intercalated Ni-Ti LDH.
