In Situ Synthesis of Bi2MoO6/Bi2SiO5 Heterojunction for Efficient Degrading of Persistent Pollutants

“…Furthermore, the charge transfer capability of the samples was further investigated via EIS to quantify their electron transfer efficiencies [ 30 ]. As shown in Figure 9 b, the arc radius of pure BMO and BSO is larger than that of the BMOS-3 photocatalyst, indicating that the internal resistance of the material can be reduced by constructing a heterojunction [ 31 ].…”

“…However, due to the intrinsic properties, CdS is very easy to be oxidized by photogenerated holes with strong oxidizing properties during the photocatalytic process, and photocorrosion occurs, causing low stability. − In addition, due to the effect of the Coulomb force, photogenerated holes and photogenerated electrons are prone to compounding, resulting in the reduction of the number of effective photogenerated electrons involved in photocatalytic hydrogen production. − The above problems seriously limit the practical application of CdS as photocatalysts. Constructing two or more semiconductor composites can integrate multiple semiconductor properties and also provide new paths for photogenerated electrons and holes to reduce the chance of their compounding, which has been widely studied in recent years as an effective means to prepare efficient photocatalysts. − Zhang et al prepared a direct Z-scheme highly efficient CdS/WO 3 photocatalyst, which improved the separation efficiency of electrons and holes .

Harnessing ultrasound in photocatalysis: Synthesis and piezo-enhanced effect: A review

“…Multitudinous photocatalysts, according to the composition, can be mainly categorized into oxide photocatalysts such as TiO 2 [4] , [5] , [6] , [7] , [8] , [9] and Bi 2 O 3 [10] , [11] , and non-oxide photocatalysts such as CuS [12] , [13] , ZnS [14] , CdS [15] , MoS 2 [16] , [17] and carbon nitride [18] , [19] , [20] . Additionally, morphology control strategies have been employed to change the shape of photocatalysts, leading to the development of 0D, 1D, 2D, and 3D photocatalysts with/without hollow structures [21] , [22] , [23] . Enhancing visible-light absorption and reducing carrier complexation are crucial for boosting photocatalytic performance.…”
