Pd-Si-structured novel mesoporous nanocomposite catalytic materials, having quite high Pd/Si ratios, were synthesized by an acidic direct hydrothermal synthesis route. The nanocomposite catalytic materials were then characterized by XRD, XPS, EDS, nitrogen adsorption, and SEM techniques. Unlike MCM-41, the XRD patterns indicated a rather wide d((100)) band at a 2 theta value of about 1.9. The materials, with very high Pd/Si wt ratios between 1.43 and 2.66, were synthesized and had BJH surface area values between 600 and 200 m(2)/g. The pore size distributions of these materials were also quite narrow, indicating pores between 2 and 7 nm.

Hydrothermal synthesis of hydroxyapatite from calcium sulfate hemihydrate Bıngol, Onur Rauf; Durucan, Caner (2012-08-01) Commercial grade calcium sulfate hemihydrate (CaSO4·0.5H2O, or plaster of paris, PoP) an economically feasible and abundant precursor has been used in (Ca10(PO4)6(OH)2, HAp) synthesis. The synthesis was realized by reacting solid PoP precursor with 1M of (NH4)2HPO4 aqueous solution, at ambient and mild hydrothermal conditions (2 ± 0.2 atm and 120 °C). The effect of reaction temperature and pressure on PoP to HAp conversion efficiencies and reaction kinetics has been reported. The formation of HAp at a react...
Synthesis and characterization of Ba/MCM-41 Kaya, Emine; Oktar, Nuray; Karakaş, Gürkan; Murtezaoglu, Kirali (2010-01-01) Mesoporous Ba/MCM-41 type materials (Ba/MCM-41) with high Ba/Si molar ratios between 0.025 and 0.1 were synthesized by direct hydrothermal synthesis. The samples were characterized by XRD, nitrogen adsorption, TGA-DTA, FTIR, SEM-EDS, and TEM techniques. BET surface areas of samples with various Ba loadings were found between 722 and 931 m(2)/g with 28 A average pore size, which is consistent with the pore size of 30 A for pure MCM-41 samples synthesized by the same procedure. The crystal structures of synth...
Direct synthesis of hydrogen storage alloys from their oxides Tan, Serdar; Öztürk, Tayfur; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2011) The aim of this study is the synthesis of hydrogen storage compounds by electrodeoxidation technique which offers an inexpensive and rapid route to synthesize compounds from oxide mixtures. Within the scope of this study, two hydrogen storage compounds, FeTi and Mg2Ni, are aimed to be produced by this technique. In the first part, effect of sintering conditions on synthesis of FeTi was studied. For this purpose, oxide pellets made out of Fe2O3-TiO2 powders were sintered at temperatures between 900 °C – 1300...
Ni and cu incorporated mesoporous nanocomposite catalytic materials Nalbant, Asli; Doğu, Timur; Balci, Suna (2008-02-01) Nickel and copper incorporated MCM-41-like mesoporous nanocomposite materials prepared by the direct hydrothermal synthesis and the impregnation procedures showed highly attractive pore structure and surface area results for catalytic applications. The XRD patterns showed that characteristic MCM-41 structure was preserved for the materials synthesized following an impregnation procedure before the calcination step. The surface area of the Cu impregnated material with a quite high Cu/Si atomic ratio (0.19) w...
Hydrothermal and microwave synthesis of boron phosphate, BPO(4) Baykal, Altan; Toprak, M; Kniep, R (2001-01-01) BPO4 was previously synthesized by the solid state reactions of (NH4)(2)HPO4 and B2O3 at 1000 degreesC and was characterized by X-ray powder diffraction and IR methods. We have now succeeded in preparing BPO4 from H3BO3 and P2O5 using hydrothermal synthesis by heating at 160 degreesC for 2 days and obtained a single phase product. We observed that a microwave-assisted synthesis takes only 3 to 5 minutes to transform a solid mixture of (NH4)(2)B4O7. 4H(2)O, and solid H3PO4 Or B2O3 + P2O5 into the crystalline...
