Laser-synthesized TiN nanoparticles as novel efficient sorbent for environmental water cleaning
arxiv(2024)
摘要
Dyes used in industries such as textile, paper, and leather are known to be
harmful to both human health and aquatic ecosystems. Therefore, finding
effective and sustainable methods to remove dyes from wastewater is crucial for
mitigating the detrimental effects of pollution.TiN nanoparticles have good
absorption and conversion of light energy into thermal energy in the visible
range of the spectrum, which makes them promising in various applications, from
biomedical to environmental protection. In this work, it is shown that titanium
nitride nanoparticles also possess promising adsorption capabilitieseffect. TiN
nanoparticles were synthesized by laser ablation method in liquid. Water,
acetone and acetonitrile are used as solvent. Nanoparticles were characterized
by scanning and transmission microscopy, Raman spectroscopy, which showed the
formation of the under-stoichiometric titanium nitride (TiN1-x). TiN
nanoparticles are investigated as a promising object for high adsorption It is
shown that adsorption of TiN nanoparticles is associated with the electrostatic
effect and the presence of pores in the synthesized nanoparticles. Optimal dye
absorption capabilities were found to be associated with a low amount of Ti
vacancies and high amount of N vacancies acting as donor states. The particles
synthesized in water have the highest sorption capacity of dye achieving the
value of 136.5 mg/g.
