N/B co-doped polymeric carbon nitride with boosted charge transfer property and enhanced photocatalytic degradation of tetracycline

Polymeric carbon nitride, which is an excellent metal-free photocatalyst, is a good metal-free photocatalyst. N and B were successfully integrated into PCN's tri-triazine units, according to the characterization results of XPS and NMR. According to the determination of density functional theory, N/B co-doping significantly changed PCN's electronic fabric, resulting in a spatial split in NBCN for HOMO and LUMO. Tetracycline's photocatalytic degradation rate over NBCN was 2. 5 times higher than PCN. Frontier Electron Densities predicted that the vulnerably impacted sites in the tetracycline molecular.

Construction of novel metal-free graphene oxide/graphitic carbon nitride nanohybrids on carbon cloth and efficient degradation of RhB under visible light irradiation

Photocatalytic technology has a wide variety of application possibilities, but developing photocatalytic materials is vitally limited due to the inadequate photocatalytic material's low degradation rate at the present time, difficult to reuse, and other issues. This article describes a new metal-freephotocatalyst of graphene oxide/graphite-phase carbon nitride heterojunction on carbon cloth. The results reveal that the filter film photocatalytic activity of RhB degradation exhibits high photocatalytic activity.

Metal doped graphitic carbon nitride prepared by a bubbling template method for photo-degradation of organic pollutants

As the bubbling templates, a bubbling template method was used to produce metal-doped graphitic carbon nitride, as the bubbling templates. The materials' photocatalytic properties were determined by photocatalytic degradation of rhodamine B. K 0. 02 -CN, which was made with K doping and ammonium carbonate as the bubbling template, displayed the highest conversion at 17. 5 minutes, which is 3. 2 times higher than g-CN. This product was also effective at photo-degradation of other chemicals and has good reusability, and was also useful for photo-degradation of other pollutants.

CuCo and sulfur doped carbon nitride composite as an effective Fenton-like catalyst in a wide pH range

The carrier, CuCo/SCN bimetallic catalyst, was developed by pyrolysis method using sulfur doped carbon nitride as the carrier. The CuCO/SCN's active agent for oxygen deposition in neutral and weak alkaline environments was demonstrated by a similar combination of bimetals and sulfur doped carbon nitride in a synergistic reaction. The Bimetallic CuCo/SCN catalyst has a strong application potential in environmental pollution degradation.

Cu-Ni core-shell bimetallic cocatalyst decorated polymeric carbon nitride for highly efficient and selective methane production from photocatalytic CO 2 reduction

We then patterned these cocatalysts on polymeric carbon nitride for photocatalytic CO 2 reduction herein. The remarkable CO 2 conversion rate and stability of the developed catalyst are largely due to the Cu-Ni-11 core-shell cocatalyst and CN's synergistic effect, which provides significant optical absorption, CO 2 adsorption, and photoexcited charge separation. The study findings, therefore, clarify the effective design and production of non-noble bimetallic cocatalysts for photocatalytic CO 2 conversion.

DFT study of super-halogen (Al 7 ) doped carbon nitride (C 2 N) and its nonlinear optical properties

Density functional theory has been used to carry out a systematic investigation of a non-linear optical and electrical characteristic of a specific class of carbon nitride doped with super-halogen cluster in this study. At three operationals CAM-B3LYP, B3LYP, and LC-BLYP with 6-31G base set, the optimization of molecular geometries of pure C 2 N, single doped Al 7 @C 2 N, and double doped 2Al 7 @C 2 N, respectively, as well as comparison of their NLO properties are carried out. The B3LYP method is the lowest bandgap and highest first hyperpolarizability among these three methods of DFT. For A1, A2, and A3 systems respectively, the doping of Al 7 on C2N significantly improves the charge transfer characteristics by reducing the bandgap from 2. 32 ev to 0. 99 and 0. 95 ev.

Enhanced photocatalytic H 2 production of graphitic carbon nitride via implantation of lithium and potassium ions

Graphitic carbon nitride, a two-dimensional semiconductor with visible-light response, has been widely used in water splitting. The novel g-C 3 N 4 embedded by lithium and potassium ions was made by the simple molten salt method in Herein. The presence of Li + and K+ has shown that they can increase the crystallinity and narrow the band gap between g-C 3 N 4 and K+, thereby promoting carrier separation and increasing light absorption. Theoretical analysis results have also showed that the appearance of Li + and K + could greatly reduce the over potential of hydrogen evolution.

Efficient synthesis of porous graphitic carbon nitride nanosheets with different precursors via thermal condensation

The overall findings indicate that porous graphitic carbon nitride nanosheets with a varied morphology can be obtained using various precursors during this process. To obtain the best yield of graphite nitride production, it is suggested that melamine and the lower synthesis temperature be chosen based on this product yield analysis.

Photocatalytic properties of nano-structured carbon nitride: a comparison with bulk graphitic carbon nitride

Through a pyrolysis reaction involving urea and melamine, we have synthed two forms of graphitic carbon nitride. Compared to the bulk product made from melamine, the h-G 3 N 4 showed enhanced adsorption and higher photo-activity for rhodamine B reduction. After cyclic adsorption regeneration, the h-g-C 3 N 4's also shows good reusability.
