Oxygen-facilitated dynamic active-site generation on strained MoS2 during photo-catalytic hydrogen evolution

Mo-Doped/Ni-supported ZnIn2S4-wrapped NiMoO4 S-scheme heterojunction photocatalytic reforming of lignin into hydrogen

“…A few reductive organics have been applied as sacrificial agents to consume holes, such as lactic acid, 8 triethanolamine (TEOA), 9,10 methanol, 11 starch or sugars. 12 Unfortunately, extensive use of these organics for photocatalytic HER will significantly increase the cost.…”

Unique MIL-53(Fe)/PDI Supermolecule Composites: Z-Scheme Heterojunction and Covalent Bonds for Uprating Photocatalytic Performance

“…Therefore, X-ray photoelectron spectroscopy (XPS) was used to confirm the surface structure of elements and the interaction of MIL-53­(Fe) and PDI in composites . By observing the survey XPS spectra of 5PM and MIL-53­(Fe) (Figure a), it can be found that there are C 1s, O 1s, and Fe 2p peak signals in the composite material.…”

The Potential Strategies of ZnIn2S4-Based Photocatalysts for the Enhanced Hydrogen Evolution Reaction

“…The Type 1 heterojunction is a kind of semiconductor heterojunction in which the valence band and conduction band of one semiconductor are located between the valence band and conduction band of the other one. Under the irradiation of incident light, the conduction band to the electronic from high to low conduction band direction and the hole from low to high with direction, in the process of a photocatalytic oxidation-reduction reaction, will be two semiconductor materials to bring to the lower conduction band and a high price (Chao et al, 2021b;Longlu Wang et al, 2021). Different from Type−I heterojunction, Type−II heterojunction is formed by a staggered conduction band and valence band of two semiconductor materials (Jiang et al, 2019;Yan et al, 2019).…”
