Enhanced interfacial electron transfer and boosted visible-light photocatalytic hydrogen evolution activity of g-C3N4 by noble-metal-free MoSe2 nanoparticles

Fabrication of tailored rod-shaped carbon nitride, g-C3N4, decorated with MoSe2 flowers for the catalytic reduction of nitrophenol, organic dye degradation and biocompatibility studies

“…The lattice fringes in the HRTEM images (Fig. 4(a)) of CNM (6 : 1) clearly demonstrate that the d-spacing of 0.28 nm and 0.65 nm corresponds to the (100) and (002) 28,38 plane of MoSe 2 , also observed in bare MoSe 2 (Fig. 4(c)), indicating the presence of MoSe 2 over b-CN.…”

“…Recently, transition metal selenides have been applied to different areas such as photocatalysis, catalysis, solar cells, storage devices, hydrogen evolution and many more. 28 MoSe 2 contributes many intriguing properties, for instance, higher electrical conductivity, and metallic nature. Therefore, MoSe 2 also behaves as a promising candidate for catalysis and numerous other applications.…”

“…A 3D flower-like nano structured MoSe 2 formed with its layered flakes offers superior performance in catalysis owing to the presence of abundant active sites at the edge of nanosheets of MoSe 2 flowers. [29][30][31][32] There are very few reports on g-C 3 N 4 /MoSe 2 composites in photocatalytic H 2 production reaction, 28,33 degradation, 34 and ammonia formation. 35 The catalytic degradation of RhB dye and reduction of 4-NP using g-C 3 N 4 /MoSe 2 have not yet been reported, to the best of our knowledge.…”

Construction of a unique 2D/0D NiO/ZnCdS p–n hetero junction photocatalyst with highly improved photocatalytic H2 generation capacity

“…Using the radius of the arc on the EIS Nyquist plot, the inner resistances for the charge transfer in the photocatalytic response can be assessed. 50 The pristine NiO exhibited the smallest radius. Besides, the radius of the 5% NiO/ ZnCdS heterojunction nanocomposite was much smaller than that of pure ZnCdS, demonstrating its improved charge transfer properties after introducing NiO nanosheets.…”

Point‐to‐face contact heterojunctions: Interfacial design of 0D nanomaterials on 2D g‐C3N4 towards photocatalytic energy applications

“…[48][49][50] In this instance, several charge-transfer mechanisms arise when g-C 3 N 4 nanosheets are decorated with 0D nanoparticles (NPs) (Section 2). Meanwhile, numerous types of 0D semiconductor materials have been studied and used to form a strong heterojunction with g-C 3 N 4 , namely, metals/g-C 3 N 4 , 51,52 metal oxides/g-C 3 N 4 , 53,54 metal sulfides/g-C 3 N 4 , 55,56 metal selenides/g-C 3 N 4 , 57,58 metal phosphides/g-C 3 N 4 , 57,58 metal-free/g-C 3 N 4 , 59 metal carbide/g-C 3 N 4 , 60 or even ternary heterostructured photocatalysts. 61,62 The 0D NPs could play many roles such as a photosensitizer, electron reservoir, hole storage electron, and hole donor.…”
