The enhanced photocatalytic hydrogen production of the fusiform g-C3N4 modification CaTiO3 nano-heterojunction

Interplay between Mesocrystals of CaTiO3 and Edge Sulfur Atom Enriched MoS2 on Reduced Graphene Oxide Nanosheets: Enhanced Photocatalytic Performance under Sunlight Irradiation

“…The hydrogen evolved during these cycles reaches a maximum value of 3349.0 μmol g cat −1 in four hours. Also, the photocatalytic hydrogen evolution for CTMG20 photocatalyst is much higher than the other CaTiO 3 based photocatalysts reported in the literature . Furthermore, AQE is an important factor for the comparison of the activity of different photocatalysts, especially for photocatalytic hydrogen evolution.…”

MoS2 Quantum Dots Modified Black Ti3+–TiO2/g‐C3N4 Hollow Nanosphere Heterojunction toward Photocatalytic Hydrogen Production Enhancement

“…21‐1272), and the diffraction peak at 27.62° corresponds to the (0 0 2) plane of the g‐C 3 N 4 (PDF No. 87‐1526) . Restricted by the lower amount and crystallinity, the diffraction peaks of the MoS 2 QDs could be hardly observed .…”

“…In contrast, the interface heterojunction modification has been reported as another efficient way to improve the photocatalytic hydrogen production performance via promoting the photon‐generated carriers separation and transfer, because, driven by the built‐in electric field of the heterojunction, the photon‐generated carriers would be separated and transferred to each side of the heterojunction, and a series of research studies have been reported, such as CdS modification, Ag 3 PO 4 modification, and Cu 2 O modification . Among such modifications, the graphite‐phase carbon nitride (g‐C 3 N 4 ) has the overall water splitting band potential and remarkable visible light response (2.7 eV) and is regarded as one of the most ideal heterojunction materials, which has been the current hot topic. For example, Chang et al have prepared the NiCo 2 O 4 /g‐C 3 N 4 heterojunction with highly efficient H 2 production; Xu et al have fabricated the g‐C 3 N 4 /KNbO 3 heterojunction with enhanced photocatalytic HER via water splitting; and so on .…”

Recent Developments of Advanced Ti3+-Self-Doped TiO2 for Efficient Visible-Light-Driven Photocatalysis

“…Previous bands of semiconductor materials such as CdS [138], Ag 3 PO 4 [139], Cu 2 O [140] and WO 3 [141], have been combined with TiO 2 . Recently, g-C 3 N 4 has shown overall water splitting band potential and high visible light response, leading to the current trend [142,143]. Likewise, when Ti 3+ -TiO 2 is combined with semiconducting materials, better synergy can be expected than before.…”
