Embedding Monodisperse LaO_x Into Pt Nanoclusters for Ultra-Stable and Efficient Hydrogen Isotope Oxidation.

ABSTRACT: Catalytic oxidation plays a crucial role in the efficient treatment of hydrogen isotopes, with the key technical challenge being the development of high-performance catalysts to enhance isotope removal efficiency, thereby reducing environmental pollution and ensuring public radiation safety. Herein, the strategic control of platinum nanoclusters confined within silicalite-1 zeolites is reported to enhance the high removal efficiency for hydrogen isotopes under low-temperature conditions for the first time. Incorporating a single lanthanum oxide (LaO_x) into Pt nanoclusters adapts the local charge of adjacent Pt atoms, significantly altering their electronic structure. The existence of individual LaO_x species is confirmed by X-ray absorption spectroscopy and aberration-
