Summary: Ag-doped ZnO particles were synthesized by one-step microwave-assisted hydrothermal methods with different molar concentrations of Ag+ as dopant. X-ray diffraction confirmed the successful doping of Ag, which exists as interstitial atom. Scanning electron microscopy revealed bi-pillar-shaped hexagonal structures for samples without silver doping, but a single hexagonal pillar with different micro-structures for doped samples. Room-temperature photoluminescence spectra showed a co-emission of a near-bandgap emission and a broad orange emission peak, indicating the presence of a high density of oxygen interstitials. Experimental results suggested that the existence of Ag+ in solutions is the key factor for the formation of hollow single pillar structure of ZnO. The corresponding growth mechanism was proposed to understand the formation of structures.

Summary: In this study, carboxylated polyvinyl chloride/silver (CPVC/Ag) nanocomposite film was prepared and treated with gamma dosages. The optical properties of the treated films were investigated using UV spectroscopy and color difference studies. Changes in optical bandgap, refractive index, Urbach energy, and color intensity were observed with increasing gamma dosage. The domination of crosslinks and damage to the crystalline phase were found to be the cause of these changes.

Summary: In this study, ionic liquids (ILs) were used as versatile tools for interfacial engineering in perovskite photovoltaics. By manipulating the chemical structures of ILs, the properties of perovskite/SnO2 interfaces were modified to enhance the photovoltaic capabilities of perovskite devices. The relationship between IL structures and device performance was analyzed, establishing a holistic link between the two.

Summary: A novel ternary nanocomposite of Ag@RGO/ZnO was successfully synthesized using a facile one-pot method at room temperature, which functions as a low-cost, efficient, and reliable UV absorber. The optical characterization showed enhanced light absorption in the UV portion, attributed to the synergetic effect of Ag nanoparticles and RGO nanosheets. Additionally, the band-gap narrowing due to Ag-doping suggests potential applications for this nanocomposite.

Summary: This research work presents a facile phytogenic process for fabricating Ag@TiO2 nanocomposites using fennel seed extract. The nanocomposites with varying silver content were characterized using spectroscopic and microscopic techniques. The photocatalytic activity of the nanocomposites was evaluated, and it was found that 3 wt% Ag@TiO2 nanocomposites exhibited outstanding performance. The enhanced photo efficacy of the phytogenically prepared Ag@TiO2 nanocomposites was attributed to the development of an efficient and stable schottky contact between Ag metal and TiO2 surface.

Summary: In this study, silver nanoparticles of two different sizes were prepared and compounded with semiconductor materials, demonstrating the photocatalytic enhancement of the system. It was found that the hydrogen yield was almost unaffected by the silver core diameter and the hydrogen production rate was essentially the same. Additionally, the rate of hydrogen precipitation in air for 9 months was significantly higher than previous studies, providing a new idea for the study of oxidation resistance and stability of photocatalysts.
