MICROWAVE-ASSISTED HYDROTHERMAL SYNTHESIS, OPTICAL AND ELECTROCHEMICAL PROPERTIES OF AgBi(MoO4)2 NANOSPHERES

In this paper, we report the successful synthesis of novel AgBi(MoO 4 ) 2 nanospheres via a simple, rapid and reliable microwave-assisted hydrothermal approach, employing AgNO 3 , Bi(NO 3 ) 3 ⋅ 5H 2 O and Na 2 MoO 4 ⋅ 2H 2 O as starting materials. The phases and morphologies of the products were characterized by powder X-ray diffraction (XRD), energy dispersive spectrometry (EDS), X-ray photoelectron spectrum (XPS), selected area electron diffraction (SAED), transmission electron microscopy (TEM), and scanning electron microscopy (SEM). Optical property of the product gives the value of optical absorption edge energy to be 2.88 eV. Moreover, experimental result showed that obvious increase of the reduction peak was observed employing AgBi(MoO 4 ) 2 /GCE as working electrode in the presence of H 2 O 2 molecule, which indicated that the as-prepared AgBi(MoO 4 ) 2 nanospheres exhibited excellent electrocatalytic activity to H 2 O 2 .
