“…For example, Chee et al [18] used stannous octoate as a raw material, sodium borohydride as a reducing agent, and polyvinylpyrrolidone (PVP) as a surfactant to study the effects of reaction temperature, drying temperature, ultrasonic vibration, and centrifugal speed on the size of Sn nanoparticles. It was found that the size of Sn nanoparticles increased with the increase of reaction temperature and drying temperature, and the agglomeration of Sn nanoparticles was aggravated with the increase of ultrasonic and centrifugal speed [19]. However, in these methods, the Sn nanoparticles obtained by some methods are prone to agglomeration, results in uneven size and contains many impurities (such as mechanical alloying technology and arc discharge technology), some require reaction in a vacuum environment (such as PVD method), and some require harsh experimental conditions and complex operations (such as metal vapor condensation technology) [20][21][22].…”

Tin (Sn) micro-nanoparticles with special pine tree dendritic morphology were synthesized by using tin foil as the anode and titanium as the cathode through simple anodization method. Surprisingly, it is found that the morphology of Sn particles is closely related to factors such as the type of electrolyte, the concentration of the electrolyte, and the different applied voltages, and briefly discussed the influence of various factors on the growth of Sn particles. In addition, Sn particles are calcined under different temperature conditions to obtain Sn/SnO2 hybrid materials with different tin dioxide (SnO2) contents. The changes in morphology and the phase of SnO2 crystal lattices were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively, which proved the successful synthesis of Sn/SnO2 mixed materials. Finally, the Sn/SnO2 hybrid material with metal-doped modified semiconductor properties was used to photocatalytic degradation of simulated organic pollutants rhodamine B (RhB). It was found that the photocatalytic degradation efficiency of the Sn/SnO2 hybrid material under simulated sunlight conditions is near 90% in 5 h. Therefore, this work provides a convenient and effective environmental protection approach for the treatment of architecture and industrial dyes.

“…To tune the morphology of the materials, a surfactant is commonly used in the procedure, but its removal at the end of the process is very difficult, introducing issues with the performance of the materials. 11,12 Thus, the fabrication of CdS nanostructures without using any template or surfactant is a big focus of researchers.

CdS is one of the semiconductor nanomaterials (band gap: ∼2.42 eV) that has been exploited for its unique physical, chemical, and optical properties, notably for its good charge carrier capacity and photocatalytic activity. Additionally, CdS possesses good Lewis acidity to contend as an emerging efficient heterogeneous catalyst for organic transformation reactions. In this work, a very simple and easy-to-handle method has been utilized to fabricate diverse CdS nanostructures (CdS_1a–CdS_6a) from a mixture of {[Cd2(bpta)2(adc)2]·2H2O} n or {Cd2(bpea)2(adc)2} n (where bpta = N,N′-bis(pyridyl-t-butyl) amine, bpea = N,N′-bis(pyridylethyl) amine, and adc = acetylene dicarboxylate) and thiourea as the Cd2+ and S2– sources, respectively, in three different solvents (methanol, ethanol, and tert-butanol) under solvothermal conditions at 120 °C for 6 h. Moreover, a time-dependent evolution study was utilized for the understanding of their formation at optimized conditions. Their varied morphologies (hollow and porous) were confirmed by field-emission scanning electron microscopy (FESEM). The crystallinity and bulk phase purity of all CdS nanostructures was confirmed by powder X-ray diffraction (PXRD), energy-dispersive X-ray (EDX) spectroscopy, X-ray photoelectron spectroscopy (XPS), and high-resolution transmission electron microscopy (HRTEM). On the basis of their solid-state ultraviolet–visible (UV–vis) diffuse reflectance spectra, the band gap values in the range of 2.441–2.5 eV were calculated from the Tauc plot. Their porosity and surface area were measured by a N2 adsorption experiment. Furthermore, the emission spectra showed maximum intensity in the case of nanostructures fabricated in ethanol, followed by those fabricated in methanol and tert-butanol, respectively. Among all of the nanostructures, as-synthesized CdS_3a was found to be the best heterogeneous catalyst to prepare several bis(indolyl)methanes (BIMs) at room temperature under solvent-free conditions. The recyclability up to three cycles and the stability of the catalyst were also confirmed.
