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.

Hydrothermal synthesis of TiO hollow spheres adorned with SnO quantum dots and their efficiency in the production of methanol via photocatalysis.

TiO hollow spheres and TiO hollow spheres adorned with SnO quantum dots were synthesized successfully under mild temperature and autogenous pressure using the hydrothermal route. X-ray diffraction, field emission scanning electron microscopy, scanning electron microscopy, transmission electron microscope, photoluminescence spectroscopy, and UV-vis spectroscopy were used to characterize the physical and chemical nature of the synthesized sample. The characterized samples were used in the photocatalytic applications to reduce the concentration of carbon dioxide in the presence of water under the influence of visible light.
