STUDY OF HETEROLYTIC DITHIOLENE COMPLEXES OF Ni(ΙΙ) FOR HYDROGEN PRODUCTION BY PHOTOCATALYSIS AND ELECTROCATALYSIS
Summary:
The main area of study is the production of hydrogen by heterolytic dithiolene-diimine complexes of Ni (II) by photocatalysis and electrocatalysis as well as their spectroscopic study to check the stability of the two systemsand investigate the mechanism of the catalytic action of the complexes. During this research two Ni (II) catalytic complexes that were synthesised by the phD candidate Sophia Ballou of our laboratory, were initially examined by spectroscopic techniques such as UV-Vis andcyclic voltammetry (CV). Subsequently, hydrogen detection studies were carried out in the following photocatalytic systems:
 System 1:The [Ni(pq)(qdt)] was considered as catalyst in a photocatalytic system which had the fluorescein as photosensitizer and the triethanolamine (TEOA) as electron donor.
 System 2: The [Ni((pq)bdt] was considered as catalyst in a photocatalytic system which had the fluorescein as photosensitizer and the triethanolamine (TEOA) as electron donor.These experiments were carried out using dimethylformamide (DMF) and water as solvent. Gas chromatography with thermal conductivity detector (TCD) was used for H2 detection.
