Synergistically interactive P–Co–N bonding states in cobalt phosphide-decorated covalent organic frameworks for enhanced photocatalytic hydrogen evolution

Abstract

Non-noble materials with high efficiency and stability are essential for renewable energy application. Herein, cobalt phosphide nanoparticles-decorated covalent organic frameworks (CTF-CoP) are synthesized via an in-situ self-assembly method combined with...

Strategies to improve the photocatalytic performance of covalent triazine frameworks

“…18. 214 Carbon materials such as carbon quantum dots (CQDs), carbon nanotubes (CNTs), and graphene oxide (GO) have found widespread use in various elds, including photocatalysis, electrocatalysis, sensing, and bioimaging, attributable to their unique photoelectric properties, quantum connement effects, high photochemical stability, and environmentally friendly nature. [215][216][217] In the study of CQDs/CTFs for photocatalytic hydrogen evolution from water, photoelectrochemical characterization revealed that the introduction of CQDs not only extended the visible light response range but also helped in electron storage, with the light emitted in its multiphoton active process being captured by CTF-1 to enhance the separation of photogenerated electron-hole pairs.…”
