Acidity and Catalytic Activity of Zinc Sulfide

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Antimicrobial Activity and Photocatalytic Degradation Properties of Zinc Sulfide Nanoparticles Synthesized by Using Plant Extracts

Biological synthesis of zinc sulfide (ZnS) nanoparticles (NPs) was prepared by a simple co-precipitation method using methanol plant extracts of Tridax procumbens, Phyllanthusniruri, and Syzygium aromaticum. The as-prepared ZnS NPs was examined by several physiochemical techniques such as X-Ray Powder Diffraction (XRD), Scanning Electron Microscopy (SEM), UV-Visible spectroscopy, Fourier Transf...

Electrochemical Synthesis and Characterization of Zinc Sulfide Nanoparticles

Electrosynthesis process has been used for preparation of zinc sulfide nanoparticles. Zinc sulfide nanoparticles in different size and shapes were electrodeposited by electrolysis of zinc plate as anode in sodium sulfide solution. Effects of several reaction variables, such as electrolysis voltage, sulfide ion concentration as reactant, stirring rate of electrolyte solution and temperature on p...
