Construction of MnCo2S4/S-BiOCl S-Scheme Heterojunction Nanocatalysts for Efficient Visible-Light-Driven Oxidative Coupling of Benzylamine via Cooperative Electron–Hole Utilization
Photocatalytic selective oxidation of amines to imines has attracted wide attention because of the high value of imines in pharmaceuticals, agrochemicals, and fine chemicals. However, most photocatalysts are constrained by insufficient visible-light absorption, rapid charge recombination, and inadequate redox capabil...

Versatile Co3O4@metal oxide nanocomposites: from photocatalytic pollutant degradation to high-efficiency energy supercapacitor storage
Co3O4-based heterojunction nanocomposites (Co3O4@M-Ox; where M = Zn, Ti or Cu) were synthesized using a simple, cost-effective, eco-friendly hydrothermal method. These nanocomposites can be used in a variety of applications. Characterisation using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR),...

Visible-light Driven Photocatalytic Degradation of Rhodamine B over Ce-g-C3N4 Composite: Structure -activity Relationship Study
Graphitic carbon nitride (g-C3N4) has emerged as a promising visible-light-responsive photocatalyst for wastewater treatment. However, its practical application is hindered by limited visible-light absorption and the rapid recombination of photogenerated charge carriers. In the present study, a cerium-modified graphiti...

Shape‑Dependent Co3O4/Zn2InS4 p-n Facet Heterojunctions: Modulating Built‑In Electric Field Toward Long‑Lived Charge Separation for Boosted Photocatalytic Hydrogen Evolution.
Photocatalytic water splitting for H2 generation represents a promising pathway for converting solar energy into clean chemical fuels, yet the efficiency is often limited by sluggish charge separation and inadequate utilization of photogenerated carriers. Here, we rationally design a novel p-n heterojunction photocatal...
