“…Other absorption peaks of carbonate ions appear at 878 cm −1 for sharp ν 2 vibration, 745 cm −1 for sharp ν 4 vibration, and 1085–1070 cm −1 for weak ν 1 vibration. In addition, the appearance of the PSS absorption peak was around 1000–1200 cm −1 32,37 . According to these results, only the vaterite phase of CaCO 3 was present in this compound; there were no other peaks for the calcite and aragonite phases.…”

Silk fibroin is a unique biomaterial and has gained much attention in biomedical applications. In this study, we have demonstrated the formation of hollow fibroin using the selective etching method. Initially, spherical CaCO3 was synthesized in the presence of polyelectrolyte, poly(4‐styrenesulfonate). CaCO3 particles were treated with aqueous silk fibroin solution, followed by methanol treatment. The sequential deposition of silk fibroin was achieved through a layer‐by‐layer (LbL) strategy to obtain fibroin‐encapsulated CaCO3. Finally, the fibroin‐ encapsulated CaCO3 was treated with an acid solution to form hollow fibroin. The crystalline phase of as‐prepared products was measured using powder X‐ray diffraction, and vibrational modes of products were characterized using Fourier transform infrared spectroscopy. The hollow fibroin morphology was examined using electron microscopy. The resultant hollow fibroin has good stability and can be explored in various applications.

“…X‐ray diffraction (XRD) analysis was performed to examine the crystal structure of the Ag‐NPs‐Amine (Figure 1c). The XRD pattern matched the fcc phase of Ag (JCPDS‐04‐0783) 17 . The Scherrer equation was employed to observe the crystallite size, utilizing the full width at half maximum (FWHM) of the (111) plane 18 .…”

Electrochemical CO2 reduction to carbon monoxide (CO) is immensely important for sustainable CO2 recycling. In this study, we established a facile synthetic method for large‐scale production of Ag nanoparticles, which can be used for the selective electrochemical reduction of CO2 to CO. Thermal decomposition and reduction of AgNO3 produced Ag nanoparticles on a gram‐scale in high yield (over 90%) with a homogeneous size distribution. The oleylamine‐capped Ag nanoparticles were quasi‐spherical with diameters of 9 ± 2 nm. Ag nanoparticles are capable of electrochemical CO2 reduction to CO with high activity and stability. The CO selectivity of the catalyst was in the vicinity of 90% over a wide potential range and reached 94.2% at −1.4 V vs. RHE. The Ag nanoparticles showed good stability over 24 h. Different surface functional groups, for example, thiol and citrate were investigated to understand their influence on the variation in CO selectivity.
