Meeting of the Princeton ACS Section Tuesday, March 12, 2024 Professor Michel. W. Barsoum Drexel University, Philadelphia, PA “1D Lepidocrocite Titania-based Nanomaterials, Their Diverse Morphologies and Exceptional Properties” Frick Chemistry Laboratory, Taylor Auditorium, Princeton University Mixer (in Atrium) 6:30 pm; Lecture 7:00 pm   Abstract: Recently, we converted 15 binary and ternary titanium carbides, nitrides, borides, phosphides, and silicides into lepidocrocite-based, one dimensional, 1D, sub-nanometer nanofilaments, NFs, ≈ 5x7 Å in cross-section by reacting them with a tetramethylammonium hydroxide, TMAH, aqueous solution at ≈ 85 °C range for tens of hours. In some cases, the conversion is 100 % precluding the need for centrifuges, filters, etc. We currently routinely make 100 g batches in a lab setting. Depending on with what and the order the reaction products are washed, the 1D NFs self-assemble into loose, spaghetti-shaped fibers, ≈ 30 nm in diameter, fully inorganic TiO2 gels, pseudo 2D or porous mesoscopic particles. In all cases, the fundamental building block is 1D lepidocrocite NFs, ≈ 3 nm long, that self-assemble into the aforementioned morphologies. At this time, we believe that our materials are the only thermodynamically stable 1D NFs in water, with important implications in photo- and chemical catalysis. The production
