On the chemical grafting of titanium nitride by diazonium chemistry

摘要: Current research directions with the aim of extending applications titanium nitride (TiN) in areas microelectronics, electrocatalysis, biosensors etc. require identifying new and efficient methods to modify this durable material desired organic functionalities. We have clearly demonstrated work that diazonium chemistry can be considered for surface modification nitride. Indeed, a near-monolayer aminophenylene has been reported spontaneously grafted onto TiN by simple immersion substrates into an acidic solution corresponding cations. X-ray photoelectron spectroscopy measurements strongly suggested covalent coating aminophenyl groups on Surface functionalization layers was also investigated presence hypophosphorous acid iron powder. Effect these homogeneous heterogeneous reducing agents respect formation aryl at different thicknesses discussed detail basis conventional hemolytic dediazoniation mechanism combination XPS results.
