“…As can be seen in Figure 4b,t he XPS peaks of the S2pl ocated at 161.37 and 162.47 eV are in accordance with the 2p 1/2 and2 p 3/2 of S 2À in CdS LDH .T hese results suggestt he successful formation of CdS. [37] Besides that, the element Al is also detected, with a binding energy of 74.95 eV (Figure 4c). This is consistent with our design that the amorphous aluminam atrix remains with the formation of CdS LDH during the sulfurationprocess.…”

Efficient Photocatalytic Hydrogen Generation from Water over CdS Nanoparticles Confined Within an Alumina Matrix

et al. 2017

In this work, CdS nanoparticles embedded in an alumina matrix were successfully synthesized using layered double hydroxides (LDHs) as the precursor and template, denoted as CdSLDH. The as‐prepared CdSLDH were characterized by XRD, UV/Vis diffuse reflectance spectroscopy, TEM, HRTEM, X‐ray photoelectron spectroscopy, photoluminescence and time‐resolved fluorescence spectra. The photocatalytic hydrogen evolution rate over CdSLDH is much higher than its counterpart without the alumina matrix, that is, almost two times higher under the same conditions. The enhanced hydrogen generation performance can be attributed to the segregation and growth‐inhibiting effects of the alumina matrix. In addition, CdSLDH also displays strong fluorescence properties and a long lifetime of photogenerated charge carriers.

“…Figure b contains the spectra of C1s; the peaks located at 284.1, 284.4, and 288.3 eV are attributed to contributions of sp 2 C=C bonds, sp 3 C–C bonds, and C=O bonds, respectively. As illustrated in Figure c, two peaks situated at 404.5 and 411.3 eV can be detected, which correspond to the Cd 3d 5/2 and Cd 3d 3/2 photoelectrons of the Cd 2+ species in CdS, respectively. The S 2p of this sample can be decomposed into two Gaussian peaks with binding energies at 161.3 and 162.1 eV (Figure [d]).…”

A silver (Ag)-loaded biostructured carbon/cadmium sulfide (CdS) lamellar composite photocatalyst was synthesized using a hydrothermal and photodeposition method. Camellia petals functioned both as a biological layered template and as a source of carbon. The prepared composite photocatalyst demonstrated good absorption under visible light and exhibited excellent photocatalytic degradation performance. The photocatalytic degradation efficiency of the obtained 457 composites substantially improved compared with pure CdS. The 5 wt.-% Ag-loaded C/CdS sample exhibited the highest photocatalytic activity, reaching 96.5 % after 180 min, which was 8.7 times that of pure CdS. Specifically, the biocarbon sheet enhanced the absorption of visible light. Furthermore, the high electrical conductivity of Ag can effectively transfer and separate photogenerated electrons and holes, thus enhancing both photocatalytic performance and stability.

“…In this work, a facile solvothermal methodology was devised to prepare the HBSMs with a mixed solvent of GC and IP (1 : 1, v : v). As is well known, the solvents generally render certain effects on the crystal growth and even phase composition of a semiconductor over the solvothermal process [32][33][34]. To this end, the GC or IP was also adopted as a single solvent to synthesize BiOBr samples, as depicted in Table 1.…”

In this work, hierarchical hollow BiOBr submicrospheres (HBSMs) were successfully prepared via a facile yet efficient solvothermal strategy. Remarkable effects of solvents upon the crystallinities, morphologies, and microstructures of the BiOBr products were systematically investigated, which revealed that the glycerol/isopropanol volumetric ratio played a significant role in the formation of hollow architecture. Accordingly, the underlying formation mechanism of the hollow submicrospheres was tentatively put forward here. Furthermore, the photocatalytic activities of the resulting HBSMs were evaluated in detail with photocatalytic degradation of the organic methyl orange under visible light irradiation. Encouragingly, the as-obtained HBSMs with striking recyclability demonstrated excellent visible-light-responsive photocatalytic performance, which benefits from their large surface area, effective visible light absorption, and unique hollow feature, highlighting their promising commercial application in waste water treatment.
