Manganese/TiO2 composites are prepared by a solvothermal process starting from the precursors titanium propoxide and manganese nitrate. The solvothermal processes are driven at temperatures of 140 °C or 180 °C. The formation of anatase as crystalline TiO2-phase was determined by XRD for preparation conditions at 180 °C. The occurance of crystalline phases in nanometer scale is determined furthe...
In this work, the synthesis of porous structure of cadmium oxide with multilayered sheet-like morphology in nano-meter size using adipic acid as soft template by solvothermal/thermal decomposition process is reported. Chemical analyses exhibited that the formation of porous sheet-like structure is originated from bidentate coordination mode of adipate units to Cd-center. It was found that the c...
Flower-like CdSe architectures composed of ultrathin nanosheets were prepared via a facile solvothermal method. A relationship was established between the solvothermal temperature and the product structure, and thus the photocatalytic activity. When compared with well-studied CdSe quantum dots, the ultrathin nanosheet assemblies exhibited a better photocatalytic H2 evolution activity under visi...
using fe(no3)3.9h2o, co(no3)2.6h2o and mn(no3)2.4h2o the magnetic properties of nanoparticles trimetalic iron - cobalt - manganese, with supported magnesium oxide have been prepared by co-precipitation and solvothermal methods. the prepared samples are characterized by scanning electron microscope (sem), x-ray diffraction (xrd), vibrating sample magnetometer (vsm) and brunaer-emmett-teller (bet...
