Hierarchical 3D NiO–CdS heteroarchitecture for efficient visible light photocatalytic hydrogen generation

Quantum-dot sensitized hierarchical NiO p–n heterojunction for effective photocatalytic performance

“…UV-vis spectroscopy lead to a wide bandgap value of 3.3 eV which is in line with the reported bandgap (3.2–4.0 eV) values of NiO. 34 On the other hand, the spectrum of the NiO/CdS nanocomposite is very interesting: two clear linear slopes are visible in the spectrum indicating strong absorption at 2.4 eV and 3.3 eV. 53 The lower energy one belongs to NiO/CdS and it leads to a bandgap of 2.4 eV.…”

Promotion effect of nickel loaded on CdS for photocatalytic H 2 production in lactic acid solution

“…5b is the high-resolution XPS survey spectrum of the Ni peaks. The observed binding energy of Ni 2p 3/2 at 852.0 eV and 855.2 eV indicated the deposited nickel compounds on the surface of CdS contained metallic Ni and NiO [28,29], which was consistent with TEM results. The high-resolution XPS spectrum of Ni of the sample CNR was shown in Fig.…”

Highly Efficient CdS/WO 3 Photocatalysts: Z-Scheme Photocatalytic Mechanism for Their Enhanced Photocatalytic H 2 Evolution under Visible Light

“…This may indicate that Pt could play as a bridge between CdS and WO 3 for charge transferring which results in enhancement of charge separation efficiency for CdS. The H 2 generation activity for WPC3 seems to be higher than previous works, such as RGO/ZnIn 2 S 4 , NiO/CdS, TiO 2 /MoS 2 /MG, and P-MoS 2 /N-graphene tested under various tested conditions, though fair comparisons should be conducted under the same conditions such as light frequency and optical intensity.…”
