Morphological effects on the photocatalytic performance of FeVO4 nanocomposite

Construction of 1T-MoS2quantum dots-interspersed (Bi1−xFex)VO4heterostructures for electron transport and photocatalytic properties

“…Raman spectroscopy is a versatile characterization technique generally used for monitoring the local molecular bonding and structures of all types of catalytic materials. 13,34 Therefore, Raman analysis was conducted for structural information and to find the crystal local structure and electronic dimensions of materials. In Fig.…”

“…The peak at 530.20 eV is due to OH group while that at 532.37 eV is attributed to molecular water adsorbed on the surface. 13 The XPS spectrum of Fe 2p core peaks is shown in Fig. 4(f) .…”

“… 27,29,30 Among these various transition metal oxides, bismuth vanadate (BiVO 4 ) and ferric vanadate (FeVO 4 ) are potential candidates for light-driven photocatalysts due to narrow band gaps ranging from 2.0 to 2.72 eV due to their remarkable chemical stability and catalytic activity, minimal optical damage and commercial cost-effective availability. 13,24,31-33 Both BiVO 4 and FeVO 4 possess a suitable energy band in the visible light range indicating tremendous photocatalytic and electrochemical applications. 26,33–35 From a literature survey, it is observed that in scheelite ABO 4 the B site is partially filled by substituted material.…”

H2O2-assisted Sonophotocatalytic Degradation of Diclofenac using a Visible Light-Active Flower-like Micron-sized TiO2 Photocatalyst

“…For instance, Wong et al [33] reported that ZnO with pompon-like morphology led to a higher COD removal efficiency of 96.0% from treated palm oil mill effluent compared to other morphologies including rod-like (43.0%), spindle-like (56.9%) and spherical-shaped (46.6%) structures. On the other hand, nanoflower morphology has been reported to exhibit a high surface area to volume ratio and efficient photocatalytic performance for dye degradation [60]. Theoretically, the nano-sized TiO2 particles could provide a larger active surface area to trigger enhanced photocatalytic oxidation of organic compounds.…”

One-Step Preparation of RGO/Fe3O4-Fevo4 Nanocomposites As Highly Effective Photocatalysts Under Natural Sunlight Illumination

“…In addition, because of its various stable oxidizing states (+2 to +5), vanadium interacts with numerous components. However, FeVO 4 gave low photocatalytic activity, low optical absorption and poor transport of photogenerated charges which limited its applications [12,13]. Many novel composites are created as a result of this combining procedure [14].…”
