Photocatalytic Abstraction of Hydrogen Atoms from Water Using Hydroxylated Graphitic Carbon Nitride for Hydrogenative Coupling Reactions

چکیده
Employing pure water, the ultimate green source of hydrogen donor to initiate chemical reactions that involve a atom transfer (HAT) step is fascinating but challenging due its large H-O bond dissociation energy (BDE = 5.1 eV). Many approaches have been explored stimulate water for hydrogenative reactions, efficiency and productivity still require significant enhancement. Here, we show surface hydroxylated graphitic carbon nitride (gCN-OH) only requires 2.25 eV activate bonds in enabling abstraction atoms via dehydrogenation into peroxide under visible light irradiation. The gCN-OH presents stable catalytic performance N-N coupling, pinacol-type coupling dehalogenative C-C all with high yield efficiency, even solar radiation, featuring extensive impacts using renewable cleaner process dye, electronic, pharmaceutical industries.

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 کاملHighly Efficient Photocatalytic H2 Evolution from Water using Visible Light and Structure-Controlled Graphitic Carbon Nitride**
The major challenge of photocatalytic water splitting, the prototypical reaction for the direct production of hydrogen by using solar energy, is to develop low-cost yet highly efficient and stable semiconductor photocatalysts. Herein, an effective strategy for synthesizing extremely active graphitic carbon nitride (g-C3N4) from a low-cost precursor, urea, is reported. The g-C3N4 exhibits an ext...
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 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...
