Surface fluorination of α-Fe2O3 using selectfluor for enhancement in photoelectrochemical properties
Download2022-09-22
Fluorinated α-Fe2O3 nanostructures are synthesized via a facile hydrothermal route using Selectfluor™ (F-TEDA) as a fluorinating as well as growth directing agent. The addition of incrementally increasing amount of F-TEDA to Fe precursor under hydrothermal conditions resulted in preferential...
