WEB Selective Vapor Phase Syntheses of Low-Dimensional Metal Chalcogenides for Catalytic Water Splitting

Friday (25.09.2020)
09:45 - 10:00 Z: Special Symposia I
Part of:

Investigation of the interplay of metal-organic chemistry will enrich the state-of-the-art of chemical vapor deposition (CVD) technology and open new possibilities for the generation of nanostructured metal sulfide and selenide nanostructures. Therefore, novel single-source precursors exhibiting high volatility and defined thermal decomposition under (plasma-enhanced) CVD conditions through targeted synthesis strategies are reported to elaborate the precursor chemistry – materials synthesis – functional property chain. Synergistic reactivity and sufficient stability through unique ligand design to provide a precise control over compositional purity of metal chalcogenides in CVD deposits without additional chalcogenide sources. CVD-grown MEx (M = Fe, Co, Ni, Cu, Sn, In; E = S, Se) 2 D nanostructures were tested towards their (electro)catalytic applications, particular in the oxygen evolution reactions (OER). The presented CVD data opens new possibilities in the vapor phase synthesis of chalcogenide nanostructures facilitating the application as mutable earth abundant electro- or photocatalysts in OER and hydrogen evolution reactions (HER).
