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.

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 کاملPlatinum nanoparticles strongly associated with graphitic carbon nitride as efficient co-catalysts for photocatalytic hydrogen evolution under visible light.
Platinum (Pt) nanoparticles with <4 nm diameter loaded on graphitic carbon nitride (g-C3N4) by reduction at 673 K behave as efficient co-catalysts for photocatalytic hydrogen evolution under visible light (λ >420 nm). This is achieved by strong Pt-support interaction due to the high temperature treatment, which facilitates efficient transfer of photoformed conduction band electrons on g-C3N4 to...
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 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...
