Summary: The study demonstrated a single-step ultrasonic method to prepare ASA-ZnO-GO nanoparticles in aqueous solution with an average size of <70 nm. The ASA-ZnO-GO showed more efficient inhibition of E. coli growth and enhanced antioxidant properties compared to free ASA and ASA-ZnO in neutralizing hydroxyl radicals. The improved function of ASA in ASA-ZnO-GO can be attributed to the well-defined morphology and surface characteristics of ZnO-GO nanoparticles, which facilitated the complexation with ASA.

Summary: A plant biomass mediated ecofriendly synthesis approach was used to design gold nanoparticles (gAuNPs) on reduced graphene oxide (RGO) using Averrhoa carambola leaf extract at room temperature. The combination of folded RGO sheets and polar biomolecules of the leaf extract helped enhance the growth inhibition effect and significantly reduce the size of gAuNPs in the nanocomposite. The synthesized compound was characterized using various techniques including XRD, TEM,STEMHAADF, Raman, FT-IR, and UV-Vis DRS spectra, revealing a size of 8±3 nm for gAuNPs on 2D-RGO sheets. The gAuNPs loaded on RGO exhibited high photocatalytic degradation rates for various pollutants under visible light irradiation.

Summary: Magnesium aluminate (MgAl2O4, MAO) and silver doped magnesium aluminate (Ag-MgAl2O4, Ag-MAO) nanomaterials were synthesized using co-precipitation technique. Reduced graphene oxide composite (Ag-MgAl2O4@rGO, Ag-MAO@rGO) was prepared by ultrasonication method for photocatalytic degradation of crystal violet (CV) and phenol in organic effluents. The formation of doped and bare MgAl2O4 was confirmed by XRD, identified functional groups using FTIR, morphology observed by SEM, and optical analysis performed using UV-Visible spectrophotometer. Ag-MAO@rGO exhibited 81.89% CV degradation and 40.51% phenol degradation under sunlight, with hydroxyl radicals as the principal photoactive species.

Summary: In this study, CdSe quantum dots (QDs) combined with [FeFe] hydrogenase mimics were utilized as molecular catalytic reaction centers for photocatalytic hydrogen generation. The direct linking of [FeFe] hydrogenase mimics to the QD surface established a close contact between the two components, enabling efficient electron transfer for hydrogen evolution. The researchers successfully functionalized the QDs immobilized in a thin-film architecture with [FeFe] hydrogenase mimics via covalent linking, achieving high catalytic activity.

Summary: Solar-powered photochemical water splitting using suspensions of SrTiO3-based photocatalyst nanoparticles has attracted attention due to its potential for green hydrogen production. Doping the SrTiO3 nanoparticles with 1% Rh introduces midgap acceptor states, reducing the free electron concentration and built-in potentials, as well as acting as recombination centers, decreasing the photocarrier lifetime and maximum achievable EQY. The absence of built-in electric fields within Rh-doped SrTiO3 nanoparticles suggests the possibility of achieving moderate electron-hole separation through a difference in mobility.

Summary: Ammonia-source is believed to influence the physical characteristics of ZnO-based nanomaterials during synthesis, and the catalytic activity is affected by the surface characteristics of semiconductor-photocatalyst. Using ammonium carbonate and tetramethyl ammonium hydroxide as ammonia-source led to differences in pore width, volume, and surface area in the resulting nanoparticles, as well as variations in violet light absorption and catalytic activity. The observed photocatalytic activities are attributed to the differences in surface characteristics between the two samples.

Summary: Cubic Ag2O-deposited anatase TiO2 nanospheres with cubic Ni0.5Zn0.5Fe2O4-core have been synthesized in a 2-stage method. The synthesized nanospheres exhibit superparamagnetic properties and are capable of absorbing UV-A light and visible light throughout the entire wavelength range. The presence of a ferrite core enables magnetic recovery of the photocatalytic nanospheres under visible light.
