Use of some catalysts in radiolytical split of water. În: Revue Roumaine de Chimie, 2002, vol. 47, pp. 165-172. ISSN 0035-39300035-3930https://msuir.usm.md/handle/123456789/11438The present paper deals with the study of catalyzed water radiolysis under the influence of γ-rays emitted by a 60Co source (Λ = 3 × 104 Ci) with a dose rate of 8.3 kGy/h, for hydrogen production. Thirty-one solid inorganic compounds, insoluble in water, were tested as catalysts. They belong to: coordination compounds of some metallic ions with organic ligands based on salycilaldehyde or naphthalenaldehyde derivatives, mixed oxides, RhCl3 supported on a Al2O 3 layer and bimetallic compounds with EDTA ligand. The released hydrogen quantity, determined by mass spectrometry, was approximately 7-35 times greater than the one produced by simple radiolysis of water, in the absence of catalysts.enEngineering controlled terms Aromatic hydrocarbonsderivativesGamma raysirradiationMass spectrometryNuclear reactorsRadiolysisWater Engineering uncontrolled terms Bimetallic compoundsIonizing nuclear radiationsIrradiation distanceSolid inorganic compounds Engineering main heading CatalystsArticle
