Fig. 1: Structural characterization of Pd/TiO2 serial catalysts.
From: Photo-thermo semi-hydrogenation of acetylene on Pd1/TiO2 single-atom catalyst
a–d AC-HAADF-STEM images of a Pd/TiO2, b Pd/TiO2-200H, c Pd/TiO2-600H, and d Pd/TiO2-600H-O300; Pd single atoms are highlighted in yellow circles. e, f DRIFT spectra of CO adsorption on Pd/TiO2-200H, Pd/TiO2-600H, and Pd/TiO2-600H-O300 e at CO saturation adsorption and f upon He purging for 2.5 min at room temperature. g XANES spectra of different Pt/TiO2 catalysts at Pd K-edge absorption edge.
