Facile one-step economical methodology of metal free g-C3N4 synthesis with remarkable photocatalytic performance under visible light to degrade trans-resveratrol
Nanoropes crafted graphitic carbon nitride (NRCN-2), prepared by a novel, cost effective and easy to scale up method. We used naphthalene to induce nanoropes like structure inside of the graphitic carbon nitride; on industrial scale, it is easy to recycle naphthalene. The Naphthalene decomposition temperature ( > 700 degrees C) is much higher than the polymerization temperature ( = 520 degrees C) of NRCN-2. At higher temperature, naphthalene molecular vapors moved vigorously through graphitic carbon nitride sheets and caused the sheets to adopt nanoropes like morphology. Photocatalyst (NRCN-2) presented extraordinary specific surface area (351.08 m(2) g(-1)), stimulated the parting effectiveness of photo-generated electrons and holes, by extending the visible light harvesting ability to 600 nm. The nanoropes adopted photocatalysts can easily degrade MO in 90 min and trans-resveratrol in 120 min. The buoyant energetic reactive species (h(+), (OH)-O-center dot and O-center dot(2)-), created during photocatalysis caused mineralization of pollutants. The apparent rate constant, half-life time period and regression coefficients for MO and trans-resveratrol calculated with the help of pseudo first order kinetics. For MO the value of K-app is 2.968 x 10(-2) min(-1), for trans-resveratrol, K-app is 2.490 x 10(-2) min(-1), corresponding half-life values are 23.354 min and 27.837 min respectively.
