Design of earth-abundant Z-scheme g-C₃N₄/rGO/FeOOH ternary heterojunctions with excellent photocatalytic activity

Abstract

Iron is one of the most abundant elements in the surface of the earth (5.1%), while rarely used as the photocatalytic hydrogen production due to its unsuitable band structure. Herein,...

Facile Synthesis of Carbon Dot Deposited γ-FeOOH Nanosheet/Polypyrrole Composite: A Robust Photocatalyst for Degradation of Antibiotics under Sunlight Irradiation with Enhanced Antibacterial Activity

“…Figure 7 presents the MS plots of γ-FeOOH, PPy, and PFL/CDs-2, validating the n-type with positive slope and p-type with negative slope charge characteristic nature of γ-FeOOH and PPy, respectively. 55,56 At the same time, the PFL/CDs-2 composite showed both the positive and negative slopes, which reveal the n-type and p-type semiconductor conductivity nature of the composite (Figure 7c). According to the semiconductor properties, the flat-band potential (E fb ) values of n-type and p-type semiconductors were practically located near the conduction band (CB) and valence band (VB), respectively.…”

Surface modification of GO/PVDF composite membrane by MXene/protonated g‐C₃N₄ nanosheets hybrids with improved dye separation and antifouling properties

“…To exfoliate the obtained g‐C₃N₄, planetary ball milling was performed at room temperature with the milled material. The ball mill cell filled with argon gas was kept rotating at a speed of 300 rpm for one day 39 . After that, the sheets were protonated by adding hydrochloric acid with stirring under ultrasonic waves.…”

“…Through the pyrolysis of melamine at 550 C for 4 h under ambient atmospheric situations, bulk g-C₃N₄ was generated. 39 To exfoliate the obtained g-C₃N₄, planetary ball milling was performed at room temperature with the milled material. The ball mill cell filled with argon gas was kept rotating at a speed of 300 rpm for one day.…”

“…The ball mill cell filled with argon gas was kept rotating at a speed of 300 rpm for one day. 39 After that, the sheets were protonated by adding hydrochloric acid with stirring under ultrasonic waves. Then, the final mixture was dried in an oven after centrifugation.…”

Design and Fabrication of Biomass Derived Black Carbon Modified g‐C3N4/FeIn2S4 Heterojunction as Highly Efficient Photocatalyst for Wastewater Treatment

“…Additionally, BC functions as an electron reservoir reducing electron-hole recombination and efficiently absorbing visible light due to its narrow band gap. [37,38] There are a few chemical materials/sources such as cellulose acetate, polyacrylamide saccharide, etc., that have been utilized to fabricate carbon-doped graphitic carbon nitride. [39][40][41][42] There are few investigations on the fabrication of carbon-doped CN using biomass material because of the thermodynamic discrepancy between light absorption and redox potential in a single carbon-doped CN photocatalyst which restricts the photodegradation of contaminates.…”
