Abstract :

By harnessing the highly energetic, highly focused, and highly penetrating properties of synchrotron hard X-rays (>7 keV) to drive decomposition reactions (e.g. KClO4+hv � KCl+2O2), we have enabled a catalytic routes of chemical synthesis of novel materials under extreme or isolated conditions with little introduction of heat. In this talk, the author will showcase recent developments in by discussing three studies that showcase useful hard X-ray photochemistry i.e., probable synthesis of CsF2 and CsF3 at high pressure via X-ray irradiation of a mixture of CsF and KBF4. Here, the KBF4 is used as a source of molecular fluorine; synthesis and ambient recovery of stable doped polymeric carbon monoxide (doped poly-CO) via irradiation of SrC2O4 pressurized to 7 GPa; successful hydrogenation and oxygenation of WO3 and intercalation of oxygen into the WO3 lattice in separate experiments via irradiation of selected mixtures of WO3 with NH3BH3 and KClO4, respectively, demonstrating a novel means to dope semiconductors with the potential of creating photocells that are more resonant with sunlight.
