A new 2D material "Ilmenene" has been exfoliated from the naturally occurring titanate ore ilmenite (FeTiO<inf>3</inf>) by employing liquid phase exfoliation in a dimethylformamide solvent by ultrasonic bath sonication. Ilmenene displays a [001] orientation that is confirmed by transmission electron microscopy. Probable charge transfer excitation from Fe<sup>2+</sup>Ti<sup>4+</sup> to Fe<sup>3+</sup>Ti<sup>3+</sup> results in ferromagnetic ordering along with the antiferromagnetic phase accompanied by enhanced anisotropy due to surface spins. The 2D nature and band gap states help ilmenene form a heterojunction photocatalyst with titania nanotube arrays, capable of broad spectrum light harvesting and separating/transferring the photogenerated charges effectively for solar photoelectrochemical water splitting.falseA Non-van der Waals Two-Dimensional Material from Natural Titanium Mineral Ore IlmeniteArticle152050025923-593111 September 2018101arJournal105
