Researchers from the Department for Environmental Sciences Dr. Raghuraj Singh Chouhan, Dr. Jan Gačnik, Dr. Igor Živković, Sreekanth Vijayakumaran Nair, and, Prof. Dr. Milena Horvat "Josef Stefan Institute" and Prof. Dr. Alenka Vesel from Department of Surface Engineering and, Dr. Primož Šket, Nigel Van de Velde and Dr. Ivan Jerman from National Institute of Chemistry and colleagues from abroad published an article entitled Green synthesis of a magnetite/graphitic carbon nitride 2D nanocomposite for efficient Hg²⁺ remediation featured on the cover of Environmental Science: Nano. In this, the authors describe the thermal-sonication technique for producing unique de novo tris-s-triazine carbon nitride nanosheets decorated with magnetite nanoparticles (M-g-CN). The novel synthesis method yields a high percentage of stable, highly selective, and reusable M-g-CN, and exhibits wide-ranging potential applications, particularly as a green adsorbent in passive samplers or materials for remediation purposes.
