![عکس صفحه اول مقاله: A simplified method to synthesize pure vanadium silicate analogue of ETS-10 A simplified method to synthesize pure vanadium silicate analogue of ETS-10](/preview/png/73538.png)
High purity microporous vanadosilicate (EVS-10/AM-6) has been hydrothermally synthesised by a simple template-free, reducing agent-free method in the absence of titanosilicate ETS-10 seeds. Direct comparison between EVS-10 and ETS-10 showed successful isomorphous substitution of titanium with vanadium in the framework. The existence of vanadium is confirmed by energy dispersive X-ray spectroscopy and inductively coupled plasma mass spectrometry. The scan electron microscopy and the X-ray diffractometry show similar crystal morphology and similar molecular structure between the as-synthesised material and the ETS-10. Preliminary results indicate a similar internal surface area to ETS-10. Similar to ETS-10, EVS-10 may be useful for semiconductor and other electronic applications. This new simplified synthesis method may allow the economical production of EVS-10/AM-6 for quantum wire and other applications.
