Precisely Tailoring Nitrogen Defects in Carbon Nitride for Efficient Photocatalytic Overall Water Splitting

Qiqi Zhang et al.

Summary: Precisely tailoring the nitrogen defects is a promising approach for enhancing the photocatalytic efficiency of C3N4. In this study, two-coordinated-N vacancies are selectively introduced into the C3N4 framework through a facile Cl- modification method, and the concentration of defects can be easily controlled by varying the usage of Cl- during thermal polymerization. The optimal defective C3N4 exhibits superior hydrogen and oxygen evolution rates and the highest apparent quantum efficiency among reported single-component C3N4 photocatalysts for overall water splitting. The Cl- modification facilitates the introduction of two-coordinated-N vacancies and promotes charge carrier separation efficiency, leading to greatly enhanced photocatalytic efficiency.

Molecular engineering of benzothiadiazole-based polymers: balancing charge transport and stretchability in organic field-effect transistors

Michael U. Ocheje et al.

Summary: Fluorination is a common strategy for improving the electronic properties of pi-conjugated materials, but its effects on thermal transitions and mechanical properties are not fully understood. This study evaluated the glass transition temperatures and mechanical properties of a series of fluorinated and/or alkylated benzothiadiazole-based polymers, and measured their electronic properties under strain through organic field-effect transistor fabrication. The results showed that fluorination embrittles conjugated polymer thin films, while alkylation softens them. The crack onset strains and electronic properties of the synthesized polymers were inversely proportional, and the electronic properties under strain increased with decreasing elastic moduli.

Sulphur vacancies-VS2@C3N4 drived by in situ supramolecular self-assembly for synergistic photocatalytic degradation of real wastewater and H2 production: Vacancies taming interfacial compact heterojunction and carriers transfer

Gen Li et al.

Summary: In this article, a universal method for the synthesis of compact heterojunction VS2@C3N4 with S vacancies was developed via in situ supramolecular self-assembly method. The material showed outstanding catalytic activity, stability, and hydrogen production rate. The presence of S vacancies resulted in the formation of a compact heterostructure and reduction of the work function, promoting interfacial carriers transfer and surface properties. The core-shell structure also improved the stability of S vacancies. This work not only provides a universal method for the construction of TMD core-shell structure with vacancies, but also deepens our understanding of carrier separation in the vacancies interface for photocatalysis.
