Abstract
Scaling the production of synthetic Two-dimensional (2D) materials to industrial quantities has faced significant challenges due to synthesis bottlenecks whereby few have been produced in large volumes. These challenges typically stem from bottom-up approaches limiting the production to the substrate size or precursor availability for chemical synthesis and/or exfoliation. The large-scale reactor has a number of advantages in terms of safety, processing, control and monitoring of the reaction, in addition to easy customizability of reaction conditions via computer interface. UV–visible spectroscopy was used to study the optical extinction (absorption and scattering) properties of the Ti3C2Tx. In general, MXene optoelectronic properties depend on solution concentration, flake size, and surface terminations. Quantification and peak fitting were conducted using CasaXPS V2.3.19. Shirley background was used for region fitting. Gaussian peak shape, was used for oxide and adventitious carbon-related moieties and asymmetric Lorentzian–Gaussian peak shape, LA, was used for remaining moieties.
