synthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
Phase Equilibria and Crystal Chemistry in Portions of the System SrO-CaO-Bi2O3-CuO, Part II—The System SrO-Bi2O3-CuO
New data are presented on the phase equilibria and crystal chemistry of the binary systems Sr0-Bi203 and SrO-CuO and the ternary system SrO-Bi2O3-CuO. Symmetry data and unit cell dimensions based on single crystal and powder x-ray diffraction measurements are reported for all the binary SrO-Bi2O3 phases, including a new phase identified as Sr6Bi2O9. The ternary system contains at least four ter...
متن کاملA NEW COMPOUND IN THE TERNARY SYSTEM, Li2O-TiO2-Nb2O5
A new compound was confirmed to be formed at around the composition Li:Ti:Nb=19:10:12 in the system Li 0-Ti0 -Nb O5 by reaction at 1100 OC for 2 120 hrs in air betaeen tf2~63, Ti0 and Nb205. This compound was also produced by reactlon of L~N~o,.o.~T~o, with Li2Ti0 . Single crystals of the compound were grown uslng a Li2Mo04 8y flux method. The crystals were shown to possess a hexagonal symmetry...
متن کاملSubsolidus Phase Relationships in the ZnO–In2O3–SnO2 System
The subsolidus phase relationships in the ZnO–InO1.5–SnO2 system were investigated at 12751C using X-ray diffraction. Each of the end members of the ternary diagram is a transparent conducting oxide. There are two substantial solid solutions in the ternary phase space, the bixbyite solid solution In2 2xZnxSnxO3 (x5 0–0.40), and the indium substituted zinc stannate spinel, Zn(2 x)Sn(1 x)In2xO4 (...
متن کاملCatalytic Effect of Nb2O5 in MgH2-Nb2O5 Ball-Milled Composites
We report a study on the desorption properties, crystallography and chemical state of MgH2 and 1 mol% Nb2O5 ball-milled composites. Desorption temperatures of the composites decreased with increase of ball-milling time. Size of MgH2 crystallites decreased during ball-milling. Reduction of Nb2O5 after ball-milling was confirmed by tracing the chemical state of Nb and was further supported by TEM...
