Nanoalloys (NAs), which are distinctly different from bulk alloys or single metals, take on intrinsic features including tunable components and ratios, variable constructions, reconfigurable electronic structures, and optimizable performances, which endow NAs with fascinating prospects in the catalysis field. Here, the focus is on NA materials for chemical catalysis (except photocatalysis or electrocatalysis). In terms of composition, NA systems are divided into three groups, noble metal, base metal, and noble/base metal mixed NAs. Their design and fabrication for the optimization of catalytic performance are systematically summarized. Additionally, the correlations between the composition/structure and catalytic properties are also mentioned. Lastly, the challenges faced in current research are discussed, and further pathways toward their development are suggested.

In the present study, undoped ZnO and CdZnO nanostructures with different weight ratios of cadmium were synthesized by the sol-gel method. Structural and optical properties were investigated by Fourier transform spectroscopy, UV-Vis spectroscopy, scanning electron microscopy, energy-dispersive analytical X-ray, X-ray diffraction, and photoluminescence spectroscopy methods. Moreover, the direct band gap is calculated by Tauc's approach. Furthermore, photocatalytic activity of all samples has been investigated under UV irradiation in an aqueous medium. Compared with pure ZnO, the band gap of the Cd-ZnO decreases and depends on the content of dopants. In addition, photocatalytic activity improves in the presence of a small amount (5 wt%) of cadmium dopant. Graphical Abstract

“…Based on our previous work [33][34][35][36], 1D nanocable-like structure Cu@AgCl NWs have been successfully fabricated through structure-director-induced assembly process and their photocatalysis activity were evaluated. The results show that as-designed Cu@AgCl nanocables exhibit high performance and stability for the catalytic degradation of 4-chlorophenol.…”
