Preparation of carbon spheres supported CdS photocatalyst for enhancement its photocatalytic H 2 evolution

Optimizing the precursor of sulfur source for hydrothermal synthesis of high performance CdS for photocatalytic hydrogen production

“…The green color of S-TAA implies that the sample may be contaminated by amorphous C formed during the hydrothermal process as similar color has been reported on carbon spheres supported CdS. 51 Tauc's plots 52 was used to estimate the band gap energy (E g ) of the CdS samples: K(hvÀE g ) 1/n ¼ F(R)hv, where F(R) is the absorption coefficient, hv is photon energy, K is a constant, and n ¼ 2 as CdS is a direct band gap material. 30,32,38 As shown in the inset of Fig.…”

Efficient and Stable Photocatalytic Hydrogen Evolution Activity of Multi-Heterojunction Composite Photocatalysts: CdS and NiS2 Co-modified NaNbO3 Nanocubes

“…DRS patterns ( Figure 6) were determined to study the optical properties. Pure NaNbO 3 and pure CdS showed obvious absorption edge at about 350 and 530 nm, conforming to previous reports, respectively (Xu et al, 2011;Wang Q. et al, 2017). The composite of NiS 2 had little effect in CdS/NiS 2 sample.…”

Rod-Shaped Carbon Aerogel-Assisted CdS Nanocomposite for the Removal of Methylene Blue Dye and Colorless Phenol

“…In contrast, sulfide-related photocatalysts have received ample attention in contemporary years due to their outstanding VLI responses and outstanding photocatalytic performance [14,15]. In the past few decades, various metal sulfide-related photocatalysts have been reported for water splitting because the sulfides of transition metals have an appropriate conduction-band locus and an associated narrow band gap; hence, such compounds are used as visible light-responsive photocatalysts [16][17][18], in contrast to other semiconducting wide band gap materials that have played a prominent role in the photocatalytic process, especially cadmium sulfide (CdS) particles, which are prominent photocatalytic materials under visible light irradiation [19][20][21]. Generally, CdS is a direct band gap (2.4 eV) material that exhibits superior photophysical and photochemical properties.…”

“…CdS nanoparticles (NPs) are broadly employed as photoadsorbents due to their unique surface morphology and porosity. Therefore, many scientists have dedicated efforts to investigating new combinations of materials to enhance the nanostructure and porosity properties [19,28]. Xiubing Li et al prepared a 3D porous aerogel with tungsten oxide nanowires, and the photocatalytic activities against organic dyes were investigated [29].…”
