“…In this way, we intend to find a 2D structural, energy band matching photocatalyst to achieve the efficient advanced H 2 production of CdS in visible light irradiation. Bi 2 MoO 6 is a kind of Aurivillius oxide semiconductor, which is composed of Bi 2 O 2 2+ layer sandwiched between MoO 4 2– . − And its narrow band gap energy (about 2.60 eV) suggests it can be easily captured by visible light. − Usually, the layered Bi 2 MoO 6 photocatalyst possesses good photocatalytic activity due to the large surface area and rich exposed active sites. , However, the rapid recombination of photoinduced carriers results in the limitation of quantum yield and restricts the photocatalytic performance due to the inherent limitation of single photocatalytic materials. Thus, it is highly desirable for us to devise Bi 2 MoO 6 -based composites for improved photocatalytic performance.…”

Recently, CdS has been intensively investigated for its excellent photocatalytic hydrogen (H 2 ) evolution property. However, the poor stability and serious photocorrosion severely influence its potential for practical application. In this work, we successfully synthesized Bi surface plasmon resonance (SPR)-promoted Z-scheme Bi 2 MoO 6 nanosheet/CdS-diethylenetriamine (Bi−Bi 2 MoO 6 /CdS-DETA) composites via an in situ solvothermal method. Crystalline structure, morphology, electrochemical properties, along with the photocatalytic H 2 evolution activity and stability, have been systematically investigated. The as-prepared Bi−Bi 2 MoO 6 /CdS-DETA composites with optimized structure exhibited advanced photocatalytic H 2 evolution activity (reach to 7.37 mmol h −1 g −1 ) and high stability. Largely exposed active sites, effective Z-scheme charge separation and Bi metal SPR effect of the two-dimension (2D) heterostructure is contributed to improve H 2 generation performance of Bi− Bi 2 MoO 6 /CdS-DETA composites. This work provides an effective way to develop solar energy utilization of CdS-based photocatalysts and guarantees a promising future for design and growth of visible light response and sustainable photocatalytic materials by taking both properties and architectural features into consideration.

“…However, hydrothermal method was generally carried out at high temperature and high pressure, which limits possible industrialized mass production. While the low-temperature molten salt method induced metal ions in photocatalyst, which might deteriorate the photocatalytic activity [32][33][34][35][36][37][38].…”

Bismuth molybdate (γ-Bi2MoO6) photocatalyst has drawn numerous attentions in the field of photocatalysis because of its band gap (2.5eV ~ 2.8eV) and good visible light response (420 ≤ λ ≤ 500 nm). However, as a kind of bismuth molybdates, there are still few studies on Bi3.64Mo0.36O6.55 (BMO), thus further exploration is needed. Herein, a simple reflux method was developed to synthesize the cubic phase BMO. This method is simple and easy to operate under atmospheric pressure, showing the great potential for large-scale production. In contrast with the nanosheet structure of Bi2MoO6, the morphology of BMO is mixture of nanorod and nanoparticle-like structure. The Motts curves show that conduction band position and the valence band position of BMO was 2.77 eV, -0.33eV and 2.44eV, respectively. A new mixed phase of 3Bi2O3•2MoO3 was appeared in BMO crystal, showing that the phase transition of BMO began at 400℃. When BMO was calcined at 300℃, photocatalytic degradation rate is up to maximu. The photocatalytic activity of visible-light range was tested and compared with γ-Bi2MoO6. BMO had a better photodegradation activity than that of the Aurigillius phase γ-Bi2MoO6 due to its larger band gap and the strong oxidation ability.
