Nanostructure-assisted charge transfer in α-Fe₂O₃/g-C₃N₄ heterojunctions for efficient and highly stable photoelectrochemical water splitting

Abstract

Development of semiconductor heterojunction is a promising and yet challenging strategy to boost the performance of photoelectrochemical (PEC) water splitting. This paper describes the fabrication of heterojunction photoanode by coupling...

S-Scheme α-Fe2O3/g-C3N4 Nanocomposites as Heterojunction Photocatalysts for Antibiotic Degradation

“…Consequently, α-Fe 2 O 3 -modified g-C 3 N 4 is considered as a highlight approach to create low-cost, efficient, eco-friendly environmental photocatalysts. Many reports showed that composite materials of α-Fe 2 O 3 /g-C 3 N 4 Z-scheme photocatalysts remarkably enhance the photocatalytic efficiency in water splitting for H 2 generation, − CO 2 reduction, ,− Cr­(VI) and As removal, , organic dye degradation, − NO oxidation, and so forth. In general, previous studies on Fe 2 O 3 /g-C 3 N 4 nanocomposites indicated that combining these two materials created a Z-scheme photocatalyst, which led to superior charge transportation and reduced recombination, leading to improved photocatalytic activity.…”

“…presented the CO 2 photoreduction performance with the Z-scheme mechanism of Fe 2 O 3 /g-C 3 N 4 , which portrays our reported mechanism. 21 Furthermore, degradation of tetracycline, 25 4-nitrophenol degradation, 33 photoelectrochemical water splitting, 73 CO 2 reduction, 22,44 methanol oxidation, 74 bactericidal performance, 75 and H 2 generation 76 applications have been reported in relation to our suggested mechanism of Fe 2 O 3 /g-C 3 N 4 .…”

Enhanced hydrogen evolution reaction performance of anatase–rutile TiO2 heterojunction via charge transfer from rutile to anatase

“…S6†), where longer transient time implies lower recombination rate. According to the calculation method described in our previous work, 50 TiO 2 -500 reveals the longest transient decay time (0.086 s), followed by TiO 2 -600 (0.070 s) and TiO 2 -400 (0.054 s).…”
