Synthesis, characterization, and photocatalytic degradation of Rhodamine B dye under sunlight irradiation of porous titanosilicate (TS)/bismuth vanadate (BiVO₄) nanocomposite hybrid catalyst

Abstract

Present work focuses on the development of hybrid nanocomposites and its application as photocatalyst in the degradation of organic dyes.

Photocatalytic Performance and Degradation Pathway of Rhodamine B with TS-1/C3N4 Composite under Visible Light

“…TS-1 has also been used to broaden the application of sunlight by coupling with another photocatalyst that responds to visible light. Adepu et al [23] pointed out that TS-1/BiVO 4 displayed better photocatalytic Rhodamine B (RhB) degradation performance under sunlight irradiation. Photocatalytic ability of TS-1 could be enhanced by coupling with BiVO 4 , similar to some other semiconductor photocatalysts [24].…”

Synthesis of a high-surface area V2O5/TiO2–SiO2catalyst and its application in the visible light photocatalytic degradation of methylene blue

“…The absorbances of the collected samples were veried using a Thermo Fisher UV-Visible spectrophotometer. 13 Due to the high-intensity peaks of VO at the same 2q value of TS, the amorphous TS peak could not be found in the PXRD patterns of the VTS catalysts. 38…”

“…7,[10][11][12] Therefore, the development of efficient and recyclable visible light-driven photocatalysts is a current need. [13][14][15][16] Vanadium pentoxide (VO) has unique characteristics; therefore, it is exploited for various applications such as in catalysts, actuators, sensors, photocatalysis, UV-driven reversible switches and lithium-ion electrode materials. [17][18][19][20][21] Recently, Fei et al synthesized VO hollow spheres via a solvothermal method, and the obtained hollow spheres were calcined.…”

“…Second, the agglomeration of the small particles allows for crystal growth [26]. The energy band structure feature is one of the important factors that play an important role in determining the photocatalytic activities of the semiconductor [13]. The optical property of CDC was investigated using UV-Vis technique.…”

“…Among these methods, photodegradation is attracted much attention because it has the ability to decompose and convert a wide range of dangerous contaminants including organic and inorganic compounds into safe by-products [3,11]. In addition, photocatalysis on the surfaces of semiconductors is regarded as one of the efficient and green solutions for solving serious environmental issues [12][13][14]. In this process, electron/hole (e − /h + ) pairs are produced in the conduction (CB) and valance bands (VB) when semiconductor materials are illuminated with light of suitable energy [15].…”
