“…The photocatalytic activity of the biologically synthesized ZnO NPs and the ZnO NPs prepared with hydrothermal method (27) was compared by monitoring the decolouration of heterocyclic dye MB under visible light irradiation. In a typical process, 20 mg ZnO NPs were added into a quartz tube containing a MB solution (50 mL, 20 mg/L), which was placed with a 15 cm distance from the lamp.…”

We reported a green and simple method for biosynthesizing zinc oxide nanoparticles (ZnO NPs) using Corymbia citriodora leaf extract as reducing and stabilizing agent. SEM, EDX, XRD, UV-VIS spectroscopy, Raman spectroscopy and TGA have been used for characterizing the biosynthesized ZnO NPs. The results indicating the ZnO NPs synthesized by C. citriodora leaf extract have high purity and the average size is 64 nm. The photocatalytic activity of the ZnO NPs has been investigated by degradation methylene blue under visible light irradiation. Due to the smaller size, the biosynthesized ZnO NPs showed an excellent photocatalytic performance. ARTICLE HISTORY

“…Li et al [29] prepared rGO/potassium niobate composite nanoscrolls as a photocatalyst, which showed high photocatalytic activity for dye degradation. Furthermore, using rGO as support material to enhance the photocatalytic activity of ZnO has been discussed intensively [30][31][32][33][34][35]. Some reports have also discussed synergetic effects of the metal and rGO in the process of photocatalytic [7,36].…”

− A series of Ce-doped ZnO (Ce/ZnO) nanostructures were fabricated using the co-precipitation method, then a simply nontoxic hydrothermal approach was proposed for preparation of reduced graphene oxide (rGO)-Ce/ZnO composites. The synthesized composites were investigated by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), photoluminescence spectroscopy (PL), electrochemical impedance spectroscopy (EIS), UV-vis diffuse reflectance spectroscopy (DRS) techniques and Raman pattern. The as-synthesized rGO-Ce/ZnO composites showed high photodecomposition efficiency in comparison with the rGO-ZnO, Ce/ZnO, pure ZnO under UV, visible-light and sunlight irradiation. The degradation of methylene blue (MB) (10 mg/L, 100ml) by 95.8% within 60 min by using rGO-2 (10 mg) under sunlight irradiation was observed. The repeated use of the rGO-2 was investigated, and the results showed almost no decay in the catalytic activity.

“…Liu et al prepared GO-CdS nanocomposites for the degradation of Rhodamine B dye under visible-light [143]. Particularly, the ZnO-graphene oxide (GO) composites exhibit better photocatalysts for various photocatalytic reactions because the introduction of GO causes the structural changes such as lattice constants and band gap energy of ZnO [144,145]. Ameen et al [146] demonstrated the synthesis of ZnO-GO nanohybrid by simple chemical route and applied it as effi cient photocatalyst for the photodegradation of Cv-dye under light illumination.…”

The fabrication of semiconducting materials with controlled size and morphology is an exciting, rapidly expanding research area for realizing the peculiar physical/chemical properties and the possible practical applications at the nano-to-microscale. Also, the technological applications for nanocomposites of organic/inorganic materials are of great interest in scientifi c research due to their unique and tunable electronic and optical properties. The semiconducting materials at nanoscale are widely used for the manufacturing of various electronic, electrical and photovoltaic devices owing to their unique band structure, optical properties, good charge mobility and ability to absorb photons from light. Among various photovoltaic devices, a regenerative photoelctrochemical solar cell called DSSC is a promising photovoltaic device for achieving reasonably high conversion effi ciency as compared to the conventional silicon solar cells. Various metal oxide semiconducting nanomaterials such as ZnO, TiO 2 , SnO 2 , Nb 2 O 5 and CeO 2 -based thin fi lm electrodes and their nanocomposites have also shown comparably good conversion effi ciency of DSSC due to their good optical and electronic properties. These semiconducting metal oxides possess high surface area which is essential for acquiring a high amount of dye
