Ammonia-induced robust photocatalytic hydrogen evolution of graphitic carbon nitride.
We report a new and effective method to prepare high activity graphitic carbon nitride (g-C3N4) by a simple ammonia etching treatment. The obtained g-C3N4 displays a high BET surface area and enhanced electron/hole separation efficiency. The hydrogen evolution rates improved from 52 μmol h(-1) to 316.7 μmol h(-1) under visible light.
متن کاملGraphitic Carbon Nitride/Reduced Graphene Oxide/Silver Oxide Nanostructures with Enhanced Photocatalytic Activity in Visible Light
Visible light active graphitic carbon nitride/reduced graphene oxide/silver oxide nanocomposites with a p-n heterojunction structure were synthesized by chemical deposition methods. Prepared samples were characterized by different physico-chemical technics such as XRD, FTIR, SEM, TEM and DRS. Photocatalytic activity investigated by analyzing the Acid blue 92 (AB92) concentration during the time...
متن کاملSurface engineering of graphitic carbon nitride polymers with cocatalysts for photocatalytic overall water splitting
Graphitic carbon nitride based polymers, being metal-free, accessible, environmentally benign and sustainable, have been widely investigated for artificial photosynthesis in recent years for the photocatalytic splitting of water to produce hydrogen fuel. However, the photocatalytic stoichiometric splitting of pure water into H2 and O2 with a molecular ratio of 2 : 1 is far from easy, and is usu...
متن کاملMechanism of Photocatalytic Water Splitting with Graphitic Carbon Nitride: Photochemistry of the Heptazine-Water Complex.
Impressive progress has recently been achieved in photocatalytic hydrogen evolution with polymeric carbon nitride materials consisting of heptazine building blocks. However, the fundamental mechanistic principles of the catalytic cycle are as yet poorly understood. Here, we provide first-principles computational evidence that water splitting with heptazine-based materials can be understood as a...
متن کاملA facile method of activating graphitic carbon nitride for enhanced photocatalytic activity.
Activated graphitic carbon nitride (g-C3N4) with enhanced photocatalytic capability under visible light irradiation was fabricated by using a facile chemical activation treatment method. In the chemical activation, a mixed solution of hydrogen peroxide and ammonia was employed. The yield can reach as high as 90% after the activation process. The activation process did not change the crystal str...
