Hydrothermally synthesized Ag2Te on metallic 2D templates
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.
期刊介绍：
Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications.
Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques.
Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals.
Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review.
The Journal is owned by the Korean Physical Society.
