NiFeB-assisted adsorption and activation of nitrogen to improve the photooxidation activity of zinc porphyrin.

This study effectively addresses the challenge of nitrogen adsorption and activation in photocatalytic nitrogen fixation by introducing an oxidizing co-catalyst, NiFeB hydroxides. The NiFeB hydroxides could provide reactive active sites and significantly enhance the nitrogen oxidation activity, offering a novel pathway for co-catalysts in nitrogen fixation reactions.

CdS/ZnS core-shell nanorod heterostructures co-deposited with ultrathin MoS cocatalyst for competent hydrogen evolution under visible-light irradiation.

Hydrogen generation via semiconductor photocatalysts has gained significant attention as a sustainable fuel generation process. To demonstrate the performance of nanoscale core-shell heterostructure in photocatalytic hydrogen production, we have fabricated CdS nanorods coated with ZnS photocatalyst via wet-chemical reaction followed by deposition of ultrathin MoS nanosheets by photo reduction process. The effect of ZnS content and suitable amount of MoS loading over the visible-light induced photocatalytic hydrogen evolution was examined in NaS and NaSO aqueous solutions.

Facile fabrication of highly catalytic-active AgCO/AgBr/graphene oxide ternary composites towards the photocatalytic wastewater treatment.

AgCO/AgBr/graphene oxide (AgCO/AgBr/GO) ternary composites with different percentages of GO were fabricated by a facile co-precipitation strategy. The composites were characterized in the aspect of phase composition, light absorption performance, and micromorphology etc. The activity of the composites was studied by photocatalytic degradation of colored organic dye (rhodamine B, RhB) and colorless organics (phenol) under the shine of visible light.

Bio-inspired honeycomb-like graphitic carbon nitride for enhanced visible light photocatalytic CO reduction activity.

Graphitic carbon nitride (g-CN) is paying attention lately owing to its interesting characteristics and substantial application in improving environmental and energy concerns. Nevertheless, the photocatalytic activity of g-CN is constrained by the inertness of the surface and particle aggregation during photocatalytic activity. Herein, we report the preparation of g-CN with honeycomb-like morphology (HC-CN) via thermal condensation of prepared SiO templates and dicyandiamide.

Fabrication of CdMoO4@CdS core-shell hollow superstructures as high performance visible-light driven photocatalysts.

CdMoO4@CdS core-shell hollow microspheres with the diameter of 2-3 μm were synthesized through a simple ion exchange hydrothermal method by using CdMoO4 solid microspheres as the sacrificial template in the presence of thioacetamide (TAA). Based on the detailed investigation it was found that the concentration of TAA in the starting solution affects the size of the CdS nanosheets and the hollowing process. At the TAA concentration of 0.

Hydrothermal synthesis of meso/macroporous BiVO4 hierarchical particles and their photocatalytic degradation properties under visible light irradiation.

An ordered hierarchical meso/macroporous monoclinic bismuth vanadate (BiVO4) particle was fabricated for the first time by a simple two-step melamine template hydrothermal method followed by calcination. The physiochemical parameters of as-prepared porous materials were characterized by means of X-ray diffraction, scanning electron microscopy, high-resolution transmission electron microscopy, Raman, Barrett-Emmett-Teller, and UV-vis techniques. The nitrogen adsorption-desorption measurement and pore size distribution curve suggest that meso/macropores exist in these hierarchical microarchitectures.

Long phosphorescent Ca2SnO4 with minuscule rare earth dopant concentration.

Rare-earth doped Ca2SnO4 phosphors were synthesized using a conventional solid state reaction method. The red phosphorescence of Eu(3+) was observed in this system with persistence time. In the as-prepared samples, the doped rare earth ions occupied both Ca and Sn sites in the host lattice.

Facile synthesis of novel hierarchical graphene-Bi2O2CO3 composites with enhanced photocatalytic performance under visible light.

A facile template-free hydrothermal approach is developed to synthesize hierarchical flower-like graphene-Bi(2)O(2)CO(3) microcomposites. The as-prepared samples were systematically characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, Fourier transform infrared spectroscopy, N(2) adsorption-desorption and UV-visible diffuse reflectance spectroscopy. The photocatalytic activity of the as-prepared samples was evaluated towards degradation of Rhodamine B (RhB) under visible light.
