Highly crystalline sulfur and oxygen co-doped g-C₃N₄ nanosheets as an advanced photocatalyst for efficient hydrogen generation

Abstract

Heteroatom doping has become a promising strategy to tailor the band structure and physicochemical properties of graphitic carbon nitride (g-C3N4). However, doping heteroatoms usually lead to decreased crystallinity, thereby an...

Photocatalytic hydrogen evolution over Pt–Pd dual atom sites anchored on TiO2 nanosheets

“…5,6 Compared with industrial hydrogen production and electrochemical hydrogen production, photocatalytic hydrogen evolution is undoubtedly the most sustainable and involves least energy consumption. 7 At present, among various semiconductors (such as CdS, [8][9][10] g-C 3 N 4 , [11][12][13] and TiO 2 (ref. 14 and 15)) as photocatalysts, titanium dioxide (TiO 2 ) is considered to be the most suitable photocatalyst for hydrogen production via water splitting due to its low cost, nontoxicity, high catalytic selectivity, and longterm photostability.…”

CoP decorated 2D/2D red phosphorus/B doped g-C3N4 type II heterojunction for boosted pure water splitting activity via the two-electron pathway

Facile Synthesis of Oxygen-Doped g-C₃N₄ Mesoporous Nanosheets for Significant Enhancement of Photocatalytic Hydrogen Evolution Performance

“…In previous studies, Shi 'group [13] conducted an investigation on the thermal gas shocking synthesis and photocatalytic performance of 2D ultrathin oxygen doped g-C3N4 photocatalysts, and found that the electronic structure of oxygen-doped g-C3N4 photocatalysts was optimized and the carrier separation rate was significantly elevated. Jia and his coworkers [14] prepared S and O co-doped g-C3N4 nanosheets through a two-step annealing process with melamine as the g-C3N4 precursor for efficient hydrogen generation. Tang' group [15] developed a defect-engineering approach to prepared O dopant and N defect in g-C3N4 framework.…”
