Efficient and stable ZrO2/Fe modified hollow-C3N4 for photodegradation of the herbicide MTSM

“…All of the chemicals used in this study were of analytical grade and were used without further treatment. 40 with slight modication according to the requirements. 60 ml of acetonitrile was put into a 100 ml Teon Autoclave, and then 2.76 g of 2,4,6trichloro-1,3,5-triazine and 0.63 g of dicyandiamide were added.…”

Carbonyl‐Grafted g‐C3N4 Porous Nanosheets for Efficient Photocatalytic Hydrogen Evolution

“…However, pristine g-C 3 N 4 exhibits limited photocatalytic activity owing to its small specific surface area, poor visible-light utilization, and fast recombination of photogenerated electrons and holes. Supramolecular assembly of CN precursors provides ag ood way to align the molecules in ap articular order.S upramolecular aggregates of melamine and cyanuric acid, [28,47,48] cyanuric chloride, [49,50] or benzoguanamine [51] connected by hydrogen bonds have been adopted to prepare nanostructured g-C 3 N 4 with high photocatalytic performance. [46] Among these methods, nonmetal doping has been demonstrated to be an effective way to incorporate externali mpurities into g-C 3 N 4 to modulate its electronic structure to achieve high photocatalytic performance.…”

“…In photocatalysis, the directional flow of electrons largely dependso nt he organization of the molecules in the structure in relationt o their crystallinity. Supramolecular assembly of CN precursors provides ag ood way to align the molecules in ap articular order.S upramolecular aggregates of melamine and cyanuric acid, [28,47,48] cyanuric chloride, [49,50] or benzoguanamine [51] connected by hydrogen bonds have been adopted to prepare nanostructured g-C 3 N 4 with high photocatalytic performance. In our previous work, supramolecular networks that consisted of cyanuric acid, ethylene glycol (EG), and melamine (CEM) were synthesized to prepare carbon self-doped g-C 3 N 4 nanosheets,w hich exhibited high photocatalytic activity owing to their extended light-harvesting capabilitya nd faster separation of photogenerated electrons and holes.…”

Soft‐Template Synthesis of Hybrid Carbon and Carbon Nitride Composites with Enhanced Photocatalytic Activity for the Degradation of Methylene Blue under Visible Light

“…But, the (002) peaks are shifted to slightly lower angles with the increase of the mass ratio of P123, reflecting an increasing interlayer distance. In addition, the (100) peak (2 θ = 13.3°) belonging to the in‐plane repeated unites of pure g‐C 3 N 4 is observed only in the XRD patterns of C/CN‐P123‐0 and C/CN‐P123‐0.2 . Obviously, this characteristic peak of C/CN‐P123‐ x becomes gradually weaker with the increase of the amount of P123, indicating that the mass ratio of P123 to PFMD can influence the textural features to some extent .…”
