Abstract

Silver telluride, Ag₂Te, was synthesized on various 2D templates of carbon nanotubes (CNT) and transition-metal dichalcogenides (WTe₂ and VTe₂) via hydrothermal synthesis. X-ray diffraction (XRD) and Raman spectroscopy revealed that Ag₂Te was synthesized on the 2D templates under optimal synthesis conditions. Differential scanning calorimetry (DSC) confirmed that the structural phase transition of Ag₂Te underwent endothermic and exothermic reactions at approximately 410 and 425 K, respectively. Among various metallic templates, a large amount of Ag₂Te has been synthesized on strongly acidic CNT. X-ray absorption near-edge structure (XANES) revealed that the chemical state of the metallic support influenced the electronic structure of the as-grown Ag₂Te on the metallic supports. Our findings demonstrated that the hybrid 2D catalysts with an appropriate 2D metallic template can be a promising strategy for achieving efficient catalysis.
