High-purity 2D MXenes synthesized using chemical vapor deposition precursors to avoid use of hazardous liquid acid etching

"MXene production relies on complex, multi-step, hazardous, expensive, difficult to scale liquid acid etching of ceramic precursors... these steps bypassed furnace heating lower-cost precursors (like titanium tetrachloride, methane)... reaction space confined/ titanium surface area controlled, causing crystalline MXene flakes to self-organize/ expand laterally into large-area, low-defect domains... scalable, low-cost, wafer-scale MXene based electronics, optics, quantum technology, batteries, sensors"
