Litchi-like CdS/CdTiO₃–TiO₂ composite: synthesis and enhanced photocatalytic performance for crystal violet degradation and hydrogen production

Abstract

CdS/CdTiO3–TiO2 composites prepared under different conditions contain a mixture of crystal phases of CdS, CdTiO3 and TiO2. The conditions of synthesis have an impact on the photocatalytic performance for dye degradation and hydrogen production.

Design of g‐C3N4/BaBiO3 Heterojunction Nanocomposites for Photodegradation of an Organic Dye and Diclofenac Sodium under Visible Light via Interfacial Charge Transfer

“…A comparison of the photocatalytic activities of different photocatalysts that have been previously described for the degradation of Rhodamine B is summarized below as shown in Figure 8a. As can be seen, the RhB removal percentage and rate constant of g‐CN/BBO (30wt%) composite were 97 % and 0.02207 min −1 within 120 minutes, respectively, which is superior to other modified g‐CN based metal‐free photocatalysts like g‐C 3 N 4 /Fe 3 O 4 /AgCl, [58] CN/Cu‐5, [56] g‐C 3 N 4 ‐BiFeO 3 ‐Cu 2 O, [53] g‐C 3 N 4 /S‐g‐C 3 N 4 , [52] g‐C 3 N 4 /Ag 3 VO 4 , [59] CQDs/g‐C 3 N 4 , [49] CCN/g‐C 3 N 4 , [51] GdVO 4 /g‐C 3 N 4 , [54] Cds/CdTiO 3 ‐TiO 2 [57] and GO/g‐C 3 N 4 [50] . Our study shows that the composite is capable of exhibiting the highest degradation efficiency within minimum time intervals as can be seen in Figure 8a.…”

The three-dimensional ordered macroporous structure of the Pt/TiO2–ZrO2 composite enhanced its photocatalytic performance for the photodegradation and photolysis of water

“…The microwave photocatalytic experiments used H-type microwave electrodeless lamps as the light source with a power of 15 W and a microwave reactor output power of 600 W; details about the microwave photocatalytic reactor can be found in the literature. 21 In the experiments, 0.15 g, 0.3 g, 0.15 g, and 0.5 g of catalyst were dispersed in the newly prepared solution (concentration of 50 mg L −1 ), and the volume was 90 mL, 220 mL, 100 mL, and 500 mL, respectively. The suspension was sonicated for 10 min, stirred in the dark for 30 min, and then placed in a photocatalytic reactor for photocatalytic experiments.…”

An overview of prominent factors influencing the photocatalytic degradation of cationic crystal violet dye employing diverse nanostructured materials

“…(1) It has become common practice in recent years to utilize CV's photodegradation as a model process and determine the photocatalytic performance of freshly developed nanomaterials. [70][71][72] (2) Several factors have contributed to the overuse of photocatalytic reactions, including the following: (3) Because CV is a frequent carcinogenic pollutant, it is especially desirable to eliminate it from aqueous media. 73 (4) In the UV-visible spectrum, the UV-visible active species CV dye shows characteristic peaks.…”
