Novel synthesis of CuHCF/B-rGO composites for oxygen evolution reaction activity.

In this work, we have focused on the preparation of copper hexacyanoferrate/boron doped rGO composites (abbreviated as CuHCF/B-rGO) by employing simple co-precipitation technique subsequently processed with ultrasonication method. The XRD spectra confirmed the existence of the cubic structure of copper hexacyanoferrate with high crystalline peaks. The prepared nanocomposite morphology was evaluated by scanning electron microscopy (SEM), and confirmed CuHCF nanoparticles formation with flake-like and wrinkled sheets.

Facile Synthesis of Ni-MgO/CNT Nanocomposite for Hydrogen Evolution Reaction.

In this study, the pristine MgO, MgO/CNT and Ni-MgO/CNT nanocomposites were processed using the impregnation and chemical vapor deposition methods and analyzed for hydrogen evolution reaction (HER) using the electrochemical water splitting process. Furthermore, the effect of nickel on the deposited carbon was systematically elaborated in this study. The highly conductive carbon nanotubes (CNTs) deposited on the metal surface of the Ni-MgO nanocomposite heterostructure provides a robust stability and superior electrocatalytic activity.

γ-Ray-Induced Photocatalytic Activity of Bi-Doped PbS toward Organic Dye Removal under Sunlight.

Photocatalysts based on semiconducting chalcogenides due to their adaptable physio-chemical characteristics are attracting attention. In this work, Bi-doped PbS (henceforth PbS:Bi) was prepared using a straightforward chemical precipitation approach, and the influence of γ-irradiation on PbS's photocatalytic ability was investigated. Synthesized samples were confirmed structurally and chemically.

Conversion and reducing agent effect on zero valent iron into FeO for photocatalytic degradation under UV light irradiation.

Conversion and reducing agent (NaBH) effect on zero valent iron into FeO nanoparticles with diverse molar ratios of reducing agent was produced through chemical reduction technique. The structural, optical, vibrational analyses were executed via XRD, UV-Vis, Raman, and FT-IR analysis. The crystallite size obtained were 35 nm, 27 nm, and 18 nm for Fe:NaBH (1:1), Fe:NaBH (1:2) and Fe:NaBH (1:3).

Effect of grinding time on bismuth oxyhalides optical and morphological properties influence on photocatalytic removal of organic dye.

Herein, we reported the synthesis of BiOX (X = Cl, Br) with different grinding time like 15 min and 30 min to analyze the evolution of physiochemical properties and the morphological evolution. The structural, optical, vibrational properties were examined by standard characterization studies. The formation of bismuth oxyhalides were confirmed by XRD and Raman studies.
