Abstract:
... Ammonia, one of the most important chemicals and an efficient energy carrier, is industrially synthesized by the energy-intensive Haber–Bosch process. Photocatalytic nitrogen fixation under ambient conditions provides an intriguing approach for the conversion of atmospheric dinitrogen into ammonia. Herein we report a plasmonic hybrid catalyst composed of Au nanoparticles uniformly embedded in the ...

Abstract:
... Ultra-thin layered structures and modified bandgaps are two efficient strategies to increase the photocatalytic performance of various materials for the semiconductor industry. In the present study, we combined both strategies in one material to form carbon-doped graphitic carbon nitride (g-C3N4) nano-layered structures by the method of melamine thermal condensation, in the presence of different m ...

Abstract:
... Developing efficient and wide spectrally acting photocatalysts for light-driven hydrogen production from water is highly desirable for solar energy conversion. Herein, diketopyrrolopyrrole (DPP) is used to combine with triphenylamine (TPA), bipyridyl (bdy), and biphenyl (bph) units for construction of conjugated microporous polymer photocatalysts. Although the synthesized two polymers, DPP-bdy-TPA ...

Abstract:
... A novel highly efficient technology, intimate coupling photocatalysis and biodegradation (ICPB) for the treatment of refractory organic pollutants was introduced, and the carrier in ICPB based on sugarcane bagasse cellulose (SBC) was prepared. The SBC–TiO₂ carrier produced was characterized using spectroscopy, microscopy, and diffraction techniques. The SEM image showed a rough and porous structur ...
