Synthesis of porous Fe3O4/g-C3N4 nanospheres as highly efficient and recyclable photocatalysts

Coupling of Bifunctional CoMn‐Layered Double Hydroxide@Graphitic C3N4 Nanohybrids towards Efficient Photoelectrochemical Overall Water Splitting

“…[6,7,27,[30][31][32][33][34][35][36][37] Additionally,g -C 3 N 4 catalysts are also applied for other energy conversion techniques (such as CO 2 reduction and photodegradation of pollutants). [38][39][40][41][42][43][44] However,i ta lso faces some disadvantages, such as al ow surface area, inherently low electrical conductivity,a nd easy recombination of electron-hole pairs. The bandgap (2.7 eV) leads to low absorption of the solars pectrum above l = 460 nm.…”

Novel magnetically separable g-C3N4/AgBr/Fe3O4 nanocomposites as visible-light-driven photocatalysts with highly enhanced activities

“…This combination helps to transfer electrons from conduction band of g-C 3 N 4 to that of the combined semiconductor, which prolongs the life times of photogenerated charge carriers. In spite of potential widespread applications of g-C 3 N 4 -based magnetic photocatalysts, there are only a few reports about preparation and investigation of their photocatalytic activities [19][20][21][22][23][24]. Nanocomposites of Fe 2 O 3 /g-C 3 N 4 have been prepared and their activities for degradation of rhodamine B (RhB) under visible-light irradiation were investigated [19,20].…”

“…Vignesh et al prepared magnetic MnFe 2 O 4 /g-C 3 N 4 /TiO 2 nanocomposite via chemical impregnation method and investigated degradation of MO under simulated solar-light irradiation [22]. Moreover, nanocomposites of g-C 3 N 4 -Fe 3 O 4 have been prepared and their activities for photocatalytic degradation of RhB and MO under visible-light irradiation were studied [23,24]. Among many magnetic materials (Fe 3 O 4 , γ-Fe 2 O 3 and MFe 2 O 4 , where M is Ba þ 2 , Ni þ 2 , Mg þ 2 , Co þ 2 , Mn þ 2 , and Zn þ 2 ), magnetite (Fe 3 O 4 ) has been widely used in preparation of magnetic photocatalysts, owing to low-cost, desirable magnetic, and nontoxic properties [25].…”

In situ construction of Z-scheme g-C3N4/Mg1.1Al0.3Fe0.2O1.7 nanorod heterostructures with high N2 photofixation ability under visible light

“…In Mg 2p, Al 2p and Fe 2p regions (Fig. 3a-c [30][31][32] For MgAlFeO(2)-CN, the binding energies in Mg 2p, Al 2p and Fe 2p regions exhibit blue-shis compared with that of MgAlFeO. This electron density change is probably due to the electron transfer from electron-rich g-C 3 N 4 to MgAlFeO.…”
