The α-Fe2O3/g-C3N4 composite as an efficient heterogeneous catalyst with combined Fenton and photocatalytic effects

Coatings of magnetic composites of iron oxide and carbon nitride for photocatalytic water purification

“…3a and SI2 † ). 30 Due to the combination of the CN materials with α-Fe 2 O 3 ( Fig. 3a ), a bathochromic shift is observed with increasing α-Fe 2 O 3 loading.…”

“…Although, dispersions show generally signicant higher activities than immobilized particles, it is essential to establish photocatalytic processes using immobilized photocatalysts. 19,20,23,[30][31][32][33] So far only a few studies focus on the immobilization of CN materials: for the photocatalytic removal of NO in air, the immobilization of carbon nitride on Al 2 O 3 foam has been reported by Dong et al 34 The immobilization of photocatalysts such as TiO 2 /C 3 N 4 composites for the photocatalytic degradation of methylene blue was presented by Boonprakob et al and is based on a doctor blade coating technique on glass. 35 Herein, we present an alternative route to obtain photocatalytically active CN-based coatings.…”

“…15,23 A common approach for iron oxide/CN composites is the hydrothermal synthesis. [30][31][32]36,37 An alternative way to obtain such composites is the microwave assisted synthetic approach. This method reveals uniform and crystalline particles in shorter reaction times at lower temperatures.…”

Recent Strategies for Hydrogen Peroxide Production by Metal-Free Carbon Nitride Photocatalysts

“…Iron-doped CN photocatalysts result on the combination of traditional Fenton and CN photocatalysis which enhances oxidation by promoting a two-channel pathway of H 2 O 2 reduction to generate HO • . In this way, many authors have synthesized iron-doped CN to try combat the disadvantage of dissolved iron in the mineralized waters [149][150][151][152].…”

Integration of Atomically Dispersed Cu–N4 Sites with C3N4 for Enhanced Photo-Fenton Degradation over a Nonradical Mechanism

“…In recent years, heterogeneous Photo-Fenton catalysts based on graphitic carbon nitride (C 3 N 4 ) have been widely investigated due to its appealing band structure, excellent electronic properties, low-toxicity and remarkable stability. , To date, a series of C 3 N 4 modified with Fe-based Fenton catalysts such as Fe single atoms, Fe clusters, Fe 2 O 3 , and Fe 3 O 4 have been fabricated and endowed with superior Photo-Fenton degradation activity. Remarkably, atomically dispersed iron anchored on C 3 N 4 exhibits an excellent catalytic performance of Photo-Fenton degradation, which can be attributed to the utmost Fe utilization and high density of electrons accumulated on Fe reactive centers .…”
