Architecture of visible-light induced Z-scheme MoS/g-CN/ZnO ternary photocatalysts for malachite green dye degradation.

The synthesis of bilayer heterojunctions has received considerable attention recently. Fabrication of novel bilayer composites is of significant interest to improve their photocatalytic efficiency. In this study, molybdenum disulfide (MoS), a layered dichalcogenide material exhibiting unique properties, in combination with graphitic carbon nitride (g-CN), a carbon-based layered material, was fabricated with small amounts of zinc oxide (ZnO).

Mint leaf derived carbon dots for dual analyte detection of Fe(iii) and ascorbic acid.

Highly luminescent carbon dots (CDs) are obtained from mint leaves adopting a simple and cost effective route devoid of additional chemical reagents and functionalization. The as-synthesized CDs are characterized by TEM, FE-SEM, XRD analysis, FTIR, Raman, UV-visible and photoluminescence spectral studies. The results reveal that the CDs have an average diameter of 4 nm with a hydroxyl-rich surface.

Redox properties and catalytic activity of CuO/γ-Al₂O₃ meso phase.

Copper oxide based systems are well appreciated for their oxidation activity. The present piece of work discusses the redox properties and catalytic activity of CuO impregnated on mesoporous alumina support. A series of catalysts with copper loading varying from 2.
