Fabrication of CdS-decorated mesoporous SiC hollow nanofibers for efficient visible-light-driven photocatalytic hydrogen production

Application of Metal/Metal Oxide Doped Electrospun Nanofiber Membranes in Sustainable Catalysis

“…Hydrogen evolution photocatalytic materials must have strong responsiveness to visible light across a broad range of wavelengths, efficient charge separation and substantial surface area in order to achieve high hydrogen generation efficiency under solar light irradiation (Liu et al, 2019). To fulfil all these characteristic features, TiO2 has been blended with co-catalysts to increase its light responsiveness which is limited only to UV light when applied alone, and high surface area TiO2 nanofibers have been developed in order to increase the charge separation efficiency.…”

Transition metal sulfides meet electrospinning: versatile synthesis, distinct properties and prospective applications

“…When CdS with a narrow band gap meets the semiconducting TiO 2 under visible light irradiation, electron transfer will occur from conduction band (CB) of photoexcited CdS to CB of TiO 2 , leading to an efficient electron-hole separation, which is also observed in other hybrid systems. [200][201][202][203][204][205][206][207][208][209][210][211][212] Then a high concentration of electrons in CB of TiO 2 and large amounts of holes in valence band (VB) of CdS are achieved. The electrons accumulated on TiO 2 can react with the oxygen molecules in the solution to produce •OH and superoxide radical anion (O 2 -), which can degrade the organic dyes effectively.…”

Performance and mechanism analysis of photocatalytic degradation of tetracycline by SiC/CdS composites

“…Main treatment methods of antibiotics include chemical oxidation, 2 biodegradation, 3 adsorption 4 and photocatalytic oxidation. 1,5,6 Among them, photocatalytic oxidation is a commonly used method to effectively degrade antibiotics, [5][6][7][8][9][10][11][12][13][14][15] and tetracycline is a research object that is often used to measure the photocatalytic degradation performance of semiconductor materials. Due to its nontoxicity and low cost, SiC has become a common semiconductor catalyst for photocatalytic degradation of antibiotics.…”

“…A series of SiC/CdS composites were constructed to form a heterostructure by altering the mass ratio of CdS. 13 By studying the performance and kinetic characteristics of tetracycline photodegradation using CdS-supported SiC/CdS composites with different mass ratios, the photocatalytic degradation mechanism of tetracycline was deeply evaluated.…”
