Mesoporous chromium oxide doped palladium catalysis for cyanation reaction of some aryl halides
(Elsevier, 2021)
A Pd/Cr2O3 hybrid catalyst for cyanation reaction of some aryl halides was synthesized and characterized by XRD, SEM/EDS and TEM. The porous structure of the catalyst was also investigated by BET analysis. All XRD ...
Catalytic activity of palladium doped activated carbon from waste coffee on some environmental pollutants
(Elsevier, 2022)
The presence of nitro compounds and such commercial dyes as Congo red, methylene blue, methyl orange and methyl red in water/wastewater causes environmental issues. The treatment of such industrial contaminants, new efficient ...
Occurrence of microplastics in herpetological museum collection: Grass snake (Natrix natrix [Linnaeus, 1758]) and dice anake (Natrix tessellata [Laurenti, 1769]) as model organisms
(Springer, 2022)
Microplastics are plastic fragments with a size less than 5 mm in length. In addition to a threat to the marine environments where these are abundantly present, these have also started polluting freshwater ecosystems. ...
Novel peripheral and non-peripheral oxobenzo[d]thiazol substituted cobalt phthalocyanines: Synthesis, electrochemistry, spectroelectrochemistry, electrocatalytic hydrogen production in alkaline medium
(Elsevier, 2022)
In this study novel oxobenzo[d]thiazol substituted cobalt phthalocyanine complexes were synthesized and characterized by FT-IR, NMR, UV-vis spectroscopy, and mass spectrometry. The redox properties of peripheral and ...
Sucrose-based activated carbon foams as an electrode active material for supercapacitors
(Springer, 2022)
Activated carbon foams (ACFs) have been successfully prepared by foaming sucrose with Zn nitrate and further chemical activation with H3PO4. The effect of the foaming agent (Zn) concentration and the activation temperature ...
Activated carbon derived from tea waste: A promising supporting material for metal nanoparticles used as catalysts in hydrolysis of ammonia borane
(Pergamon-Elsevier Science Ltd, 2020)
Activated carbons with high porosity and high surface area are promising materials to be used in wide-range applications. They can easily be prepared from various biomass source following by simple and reproducible activation ...
Novel phthalocyanines bearing 1,2,4 triazole substituents: Synthesis, characterization, photophysical and photochemical properties
(Pergamon-Elsevier Science Ltd, 2020)
4-(4,5-Diphenyl-4H-1,2,4-triazol-3-ylthio)phthalonitrile ( 3) and its non-peripherally tetra substituted zinc(II) phthalocyanine (4) and magnesium(II) phthalocyanine (5) derivatives were prepared. the novel compounds 3-5 ...
Treatment of wastewater containing organic pollutants in the presence of N-doped graphitic carbon and Co3O4/peroxymonosulfate
(Springer, 2023)
The disposal of organic pollutants is one of the important research topics. Some of the studies in this field are based on the degradation of organic pollutants with a catalytic agent. The cobalt tetraoxide/peroxymonosulfate ...
A new activated carbon-supported Pd-ZnO catalyst for Heck Cross-coupling reactions
(Elsevier, 2023)
In this work, to develop catalysts for Heck-type coupling reactions, a hybrid ZnO-Pd nanocatalyst was fabricated on activated carbon sourced from polymer debris. Such techniques as transmission electron microscopy (TEM), ...
Microplastic contamination and risk assessment in table salts: Turkey
(Elsevier, 2023)
In this study, the characterization of microplastics of table salts (n = 36) was determined by FT -IR. Then, individuals' exposure to microplastics from table salt consumption was calculated with a deterministic model, and ...
