Modulating photoelectrochemical water splitting performance by constructing a type-II heterojunction between g-C₃N₄ and BiOI

Abstract

g-C3N4/BiOI type-II heterojunction prepared by ultrasonically aided hydrothermal method exhibits high stability during PEC water splitting for up to 6000 s at 1.23 V vs. RHE.

Controllable synthesis of Co nanoparticles with the assistance of cucurbit[6]uril and its efficient photoelectrochemical catalysis in water splitting on a g-C3N4 photoanode

“…4b). [30][31][32] As expected, g-C 3 N 4 /Q[6]-Co NPs possessed a maximum photoconversion efficiency (0.0242%), which was 12.6 times and 2.3 times higher than the values of bare g-C 3 N 4 (0.00193%) and Q [6]-Co NPs (0.0104%), respectively. The higher peak ABPE value indicated that the metal/semiconductor system could The band properties and semiconductor types were determined using the Mott-Schottky (M-S) diagrams based on the electrochemical impedance-potential measurements.…”

Multifunctional materials for photo-electrochemical water splitting

“…A promising technology to utilize this solar energy is hydrogen fuel production through PEC water splitting. 69–71 Henri Becquerel first observed this phenomenon; he reported that sunlight acting on a silver chloride coated platinum electrode produced photocurrent and photovoltage in different electrolytes. The photochemical reaction cannot be stimulated in pure water as it only absorbs the infrared region, and the photon energy is low to stimulate a photochemical reaction.…”

Construction of a double heterojunction between graphite carbon nitride and anatase TiO2 with co-exposed (101) and (001) faces for enhanced photocatalytic degradation

“…In order to compound the two particles in different morphologies, various compounding methods have been tried by previous authors. 22,23 According to the literature, g-C 3 N 4 /TiO 2 photocatalysts have been synthesized by hydrothermal reaction method, sol-gel method, and so template synthesis method, etc [24][25][26] .…”
