Stimulating Protonation Capability by Eliminating Detrimental Defects in Crystalline Carbon Nitride for Photocatalytic Hydrogen Evolution

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 21, 2025

Abstract Ionothermal synthesis method often results in significant structural defects the prepared crystalline carbon nitride due to insufficient penetration of molten salt. Herein, a strategy involving addition foaming agent (NH₄Cl) precursor is adopted, which significantly enhances salt during ionothermal nitride. This more uniform internal unit and fewer detrimental (terminal amine groups hydrogen bonds formed by these groups) transformation from triazine‐heptazine mixed phase heptazine phase. improvement enables photocatalyst, upon loading cocatalysts, maximally utilize photogenerated electrons holes, establishing smooth pathway for surface protonation electron‐proton coupling. The show that photocatalytic production rate reaches 8.67 mmol g −1 h exhibits high apparent quantum efficiency 22.1% (λ = 400 nm) evolution. study elucidates relationship between crystal structure process. It also reveals impact factors on perspectives carrier behavior reaction kinetics.

Sodium Poly(heptazine imide)-Enabled Oxytrifluoromethylation of Alkenes for the Synthesis of α-CF₃ Ketones

The Journal of Organic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: March 29, 2025

This paper describes a NaPHI-catalyzed oxytrifluoromethylation of olefins under photoirradiation. The reaction is applicable for the synthesis α-trifluoromethyl ketones, which could be structurally elaborated into an array useful scaffolds. Mechanistic studies suggested that photoexcited NaPHI* facilitate formation singlet 1O2 through EnT process, thus enabling difunctionalization with trifluoromethyl radical and oxygen anion species.
