Engineered covalent triazine framework inverse opal beads for enhanced photocatalytic carbon dioxide reduction.

The development of highly ordered covalent triazine framework (CTF) materials with tailored structures is crucial for advancing functional material applications. Herein, we introduce a novel approach to fabricate covalent triazine framework inverse opal (CTF-IO) photonic crystal beads via a microfluidic-assisted assembly method and pore-confined polymerization. The polymerization process occurs within the interstitial voids of SiO nanoparticles (NPs) photonic crystals, where spatial confinement dictates the growth and arrangement of the CTF framework, resulting in a robust and precisely ordered inverse opal (IO) structure.

Preparation of Cu modified g-CN nanorod bundles for efficiently photocatalytic CO reduction.

Carbon nitride-based photocatalysts for CO reduction have received great attention. The introduction of transition metals can effectively improve the photocatalytic efficiency of carbon nitride. However, how to introduce transition metals into carbon nitride in more ways remains a challenge.

Tubular g-CN/carbon framework for high-efficiency photocatalytic degradation of methylene blue.

The preparation of high-efficiency, pollution-free photocatalysts for water treatment has always been one of the research hotspots. In this paper, a carbon framework formed from waste grapefruit peel is used as the carrier. A simple one-step chemical vapor deposition (CVD) method allows tubular g-CN to grow on the carbon framework.
