Spatially restricted strategy to construct crystalline carbon nitride nanosheet assists exciton dissociation to enhance photocatalytic hydrogen evolution activity

Shitao Yang et al.

Summary: In this study, highly crystalline carbon nitride sheets were prepared using a integrated strategy involving spatially restricted growth in solid salt media and hydrochloric acid induced exfoliation. The growth of carbon nitride was induced by K+ ions in the confined space of the solid salt, and K+ ions diffused into the carbon nitride bulk phase with feasible paths. Pickling was also used to control the K+ concentration gradient distribution and regulate the charge characteristic of cyanoamino. The carbon nitride dual-functionalized with cyanoamino and K+ (KCCN) exhibited improved photocatalytic performance with significantly higher hydrogen evolution efficiency and quantum efficiency compared to ordinary carbon nitride.

Single-Color and Two-Color Femtosecond Pump-Probe Experiments on Graphitic Carbon Nitrides Revealing Their Charge Carrier Kinetics

Shuang Song et al.

Summary: Graphitic carbon nitride related materials are promising photocatalysts. Understanding their genuine charge carrier kinetics is important for their photocatalytic applications. Two samples with different termination/functionalization groups were synthesized and studied using single-color and two-color femtosecond pump-probe experiments. The results showed that the charge carrier kinetics of CN and NCN should be measured under very low pump fluence, and higher pump fluence would introduce a short picosecond component due to carrier-carrier interactions. The derived absorption cross section of CN and NCN at pump wavelength were also determined. Overall, this study provides insights into the charge carrier kinetics of CN and NCN and their photocatalytic activities.

Efficient Exciton Dissociation in Ionically Interacted Methyl Viologen and Polymeric Carbon Nitride for Superior H2O2 Photoproduction

Yubao Zhao et al.

Summary: By anchoring cationic methyl viologen (MV) on polymeric carbon nitride (CN) photocatalyst with an anionic moiety, an ionic link is generated, resulting in an internal local electric field in the organic photocatalyst framework, which greatly enhances exciton dissociation. This study demonstrates an unprecedentedly efficient photocatalyst for the photoproduction of hydrogen peroxide (H2O2), and provides a mechanistic rationale for its remarkable catalytic performance.

Unravelling the doping effect of potassium ions on structural modulation and photocatalytic activity of graphitic carbon nitride

Chengyu Peng et al.

Summary: Graphitic carbon nitride (GCN) has been extensively studied as a promising photocatalyst, but its performance is still lacking. Metal ion doping has been proven to enhance the photocatalytic activity of GCN, and in this study, K+-doped GCN samples were prepared at different temperatures. The introduction of K+ improved the crystallinity of GCN at higher temperature, but reduced it at lower temperature. FTIR and SEM-EDS measurements showed that K+ predominantly distributed on the surface of the lower temperature sample, while it was found both on the surface and in the bulk of the higher temperature sample. The higher crystallinity of K+-doped GCN resulted in a higher H-2 evolution rate under visible light irradiation. This work provides insight for optimizing metal ion doped GCN with high photocatalytic activity.

Cyano group-enriched crystalline graphitic carbon nitride photocatalyst: Ethyl acetate-induced improved ordered structure and efficient hydrogen-evolution activity

Binbin Zhao et al.

Summary: In this study, the ethyl acetate-mediated method was developed to improve the crystallinity and prepare efficient g-C3N4 photocatalysts. The resultant cyano group-enriched crystalline g-C3N4 photocatalysts (CC-CN) displayed significantly enhanced photocatalytic hydrogen-evolution performance. The improved performance was attributed to the synergy of improved ordered structure and abundant cyano groups, promoting efficient transfer and separation of photoinduced charges as well as excellent interfacial hydrogen-generation reaction.

On-Surface Polymerization of In-Plane Highly Ordered Carbon Nitride Nanosheets toward Photocatalytic Mineralization of Mercaptan Gas

Fangsong Guo et al.

Summary: 2D carbon nitride nanosheets with in-plane highly ordered structure (PCNNs-IHO) are successfully prepared by on-surface polymerization of melamine on NaCl crystal surface at elevated temperatures. The NaCl crystals with relative high surface energy facilitate the adsorption and activation of melamine to undergo condensation reaction, and also function as unique substrates to orientate the assembly of 2D nanosheet structure. NaCl acts as a reactant to provide Na+ doping into carbon nitride matrix, affording PCNNs-IHO with robust structural base sites. PCNNs-IHO exhibits superior photocatalytic performance toward CH3SH mineralization under visible light irradiation.
