Graphitic carbon nitride (g-C3N4) is a metal-free photocatalyst with visible light response. However, the disadvantages limit its application in wider range, such as small specific surface areas, fewer active sites, narrow absorption range and high photogenic carrier recombination. In this paper, NaOH was used activator for alkaline activation of g-C3N4. The phase composition, micromorphology, ...

In this letter we extend previously established results for nested carbon nanocones to both nested boron nitride and carbon-boron nitride nanocones. Based purely on mechanical principles and classical mathematical modelling techniques, we determine the energetically favourable structures for nested boron nitride and carbon-boron nitride nanocones. While only three apex angles for boron nitride ...

A polymeric carbon nitride thin film has been grown using chemical vapor deposition. The characterization of the material shows that it same molecular composition as a formerly synthesized graphitic powder but both substances differ widely in their structural organization. In particular, our analyses reveal paradoxical character which sample exhibits simultaneously high degree organization stac...

Pectin cerium(IV) iodate (PcCeI) and (CeI) cation ion exchange materials were synthesized via sol–gel methods. The characterized by using Fourier transform infrared spectroscopy, X-ray diffractometer, thermogravimetric analysis, scanning electron microscopy. capacity (IEC), thermal stability, distribution coefficient (Kd), pH titrations investigated to recognize the behavior of materials. IEC p...

Fossil fuels are the main sources of human energy, but their combustion releases toxic compounds sulfur oxide. In oil industry, using optimal methods to eliminate from fossil is a very important issue. this study, performance montmorillonite/graphitic carbon nitride (a new hybrid nanostructure) in increasing biodesulfurization activity Rhodococcus erythropolis IGTS8 was investigated. X-ray diff...

Constructing a hierarchical structure with tunable pore size is practical method to improve the capacity of photocatalytic hydrogen production catalysts. In this work, titanium dioxide/graphitic carbon nitride (TiO2/g-C3N4) nanofibers meso/macro-porous are fabricated by combining one-step electrospinning and calcination process, in which developed introducing polyvinylpyrrolidone liquid paraffi...

Effects of physical and chemical states of iron-based catalysts on the formation of carbon-encapsulated iron nanoparticles (CEINs) synthesized thermally from kraft lignin were investigated. Experimental results indicated that if solution-based iron nitrate (FeN) was used as an iron source for the catalyst, CEINs observed were α-Fe and γ-Fe-based cores encapsulated by few layers graphitic-carbon...
