In situ synthesis of holey g-C₃N₄ nanosheets decorated by hydroxyapatite nanospheres as efficient visible light photocatalyst

Abstract

The interesting g-C3N4 nanosheet morphology has drawn huge attention in photocatalytic applications because of its special features.

Zn-doped hydroxyapatite@g-C3N4: a novel efficient visible-light-driven photocatalyst for degradation of pharmaceutical pollutants

“…41 Chahkandi et al constructed holey g-C 3 N 4 nanosheets with hydroxyapatite nanospheres, and this unique structure showed considerable degradation of bisphenol A. 42 In our present investigation, we successfully synthesized a novel heterogeneous photocatalyst, i.e., Zn-HAp@g-C 3 N 4 nanocomposite, by a facile hydrothermal method followed by ultrasonication. A variety of analytical and spectroscopic techniques were used to characterize the synthesized Zn-HAp@g-C 3 N photocatalyst.…”

Graphitic Carbon Nitride (g-C3N4): A Proficient Electrode Material for Flexible Supercapacitors

“…In contrast to nano graphite or multi-layered graphenes, the smaller stacking space between the aromatic layers in g-C 3 N 4 as a result of stronger inter-sheet binding ensures greater packing density as well as faster charge transport property perpendicular to the planes than the former ones. Moreover, the in-plane holey appearance containing regular 'lattice holes' or 'atomic deletions' within the structure that equip the nanosheets with greater number of active edges and diffusion channels, resulting in a tremendous enhanced mass charge transfer rates as well as diverts aggregation to larger extent [50] . Furthermore, relative to less polar carbons, nitrogencontaining nanocarbons are found to demonstrate improved wettability in presence of different solvents that support faster ion transportation processes across the electrode material thus benefiting the material's capacitive performance.…”

Enhancement of photocatalytic efficacy by exploiting copper doping in nano-hydroxyapatite for degradation of Congo red dye

“…One of the main fields of application of HAp is photocatalysis. A few important applications of HAp as a catalyst are the degradation of methylene blue (MB) and doxycycline drug, 1 and volatile organic compounds, 2 the deoxygenation of bio-oil, 3 the conversion of lignin derivatives into small molecular acids, 4 the degradation of bisphenol A, 5 the formation of carbon–nitrogen bonds, 6 the synthesis of alkenes, 7 the oxidation of silanes, 8 etc. HAp singly or in combination with other materials is widely utilized to degrade organic pollutants.…”
