There has been a move, globally, towards sustainable development and green energy solutions. Through the eyes of Dia Mirza, “It is critical for us to cultivate consciousness and compassion towards our environment, create awareness, galvanize people, and build sustainable innovation for sustainable development.” As such, my research focuses on mixed-ligand transition metal complexes based on functionalized pyridyl benzothiazoles for their activity towards the hydrogen evolution reaction (HER). The research aims to combine the features imparted by the functionalized pyridyl benzothiazoles with hydrazones, polypyridyl type, and triphenyl phosphine ligands in one molecule either as mononuclear systems or dinuclear systems and apply them to electro-catalytic hydrogen evolution reaction and electro-catalytic reduction of carbon dioxide.
