The stable and elastic graphitic carbon nitride/polyvinyl alcohol photocatalytic composite sponge: Simple synthesis and application for wastewater treatment

Innovative Design and Construction of Poly(Vinyl Alcohol) Coatings by Plant-Inspired Cross-Linking and Hydrogen Bonding Enabled Oil-Resistant and Strong Paper-Based Composites

“…This difference is suggestive of crosslinking between borate ions and hydroxyl groups on PVA molecules, confirming that PVA composites mimic the crosslinking of higher-order plants. 34 The O 1s XPS spectrum shown in Figure 3d can be divided into two binding energy peaks; the characteristic peaks located at 531.80/532.65, 531.68/532.11, 531.66/532.24, and 531.93/532.52 eV correspond to the adsorbed and molecular oxygen in the PVA films. 35,36 Notably, the percentage of adsorbed oxygen This lowers the hydrophilicity of PVA and thus improves oil resistance.…”

Advances in Sustainable Strategies for Water Pollution Control: A Systematic Review

“…Graphic carbon nitrite has emerged as a promising membrane material because of its unique structural properties and remarkable catalytic activity. According to Gao et al [80], graphic nitrates showed effective and efficient photodegradation and adsorption properties for removing organic pollutants from wastewater. Persistent pollution from factories has degraded our freshwater supplies and made them unsafe to drink for decades.…”

Tetracycline degradation mechanism of peroxymonosulfate activated by oxygen-doped carbon nitride

“…Graphitic-phase carbon nitride (g-C 3 N 4 ) is a widely used nonmetallic polymer because of its low synthetic costs and high chemical stability. 13–15 However, the thick lamellar structure and small specific area of g-C 3 N 4 make it non-ideal for activating PMS. 15,16 The catalytic performance of carbon-based materials can be improved by nitrogen doping 17 because the nitrogen atom has one more valence electron than the carbon atom, which makes it more electronegative.…”
