Abstract
In recent years, people pay more attention to environmental pollution and the treatment of sewage has become the focus of recent research. Palladium nanoparticles have good catalytic properties but are easy to agglomerate. Therefore, we used the electrospinning technology to prepare a uniform composite nanofiber film based on polyacrylic acid (PAA) and polyvinyl alcohol (PVA), which demonstrated that they are good carriers of palladium nanoparticles to make the nanoparticles well dispersed. Furthermore, carbon nanotubes (CNTs) were added to increase the specific surface area of the composite nanofiber film and improve its mechanical properties. The successfully synthesized PAA/PVA/CNT-COOH@palladium nanoparticle (PdNP) composite fiber films were characterized by scanning electron microscopy, transmission electron microscopy, and thermogravimetry analysis. p-Nitrophenol and 2-nitroaniline were utilized as typical pollutants to further evaluate the catalytic performance of PAA/PVA/CNT-COOH@PdNP composite fi...

Abstract It is critical in nano physics nowadays to fabricate a superior surface enhanced Raman scattering (SERS) substrate which provides the high-density ‘hot spots’ for obtaining the strong local electric field. A sensitive, large-scale and low-cost sandwich-like Ag@Cu@CW SERS active substrate was successfully fabricated by decorating the Cu and Ag nanoparticles on the cicada wing (CW) with uniformly-distributed nanopillars via a simple method with the DC magnetron sputtering system. The SERS...

Abstract Flower-like nanosheet assemblies (NSAs) of MnO2 have been synthesized with adjustable thickness and crystallinity. MnO2 NSAs in the size of about 80 nm have poor crystallinity, but display a high capacitance of 341 F g−1 at the current density of 0.2 A g−1 in aqueous MgSO4 electrolyte, while 162 F g−1 and 174 F g−1 in Al2(SO4)3 and Na2SO4 solution at 0.2 A g−1, respectively. However, there is a decrease in capacitance for 120 nm MnO2 NSAs down to 270 F g−1, 130 F g−1 and 170 F g−1 in Mg...

Abstract Metal-ligand coordination is one of the most important interactions in supramolecular assembly. Terpyridine compounds demonstrate strong metal coordination ability and can coordinate with many transition metal ions to form complexes with unique optical and electrochemical properties. In this work, new self-assembled Langmuir films of three synthesized terpyridine derivatives with different spacers were prepared by Langmuir-Blodgett (LB) technique. The interfacial phase behaviors and coo...

Recently, air pollution has become more serious and started to have a dramatic effect on the health of humans in many large cities. Generally, outdoor personal protection, such as commercial masks, cannot effectively prevent the inhalation of many pollutants. Particulate matter (PM) pollutants are a particularly serious threat to human health. Here we introduce a new efficient air filtration mat that can be used for outdoor protection. The new efficient air filter’s nanocomposite materials were ...

The effective functionalization and self-assembly of MXene are of crucial importance for a broad range of nanomaterial applications. In this work, we investigated the aggregates of sulfanilic acid-modified MXene (abbreviated as MXene-SO3H) with three model dyes at the air–water interface and demonstrated the morphological and aggregation changes of composite films, using Langmuir-Blodgett (LB) technology, as well as excellent uniformity and reproducibility by using surface-enhanced Raman scatter...

MXene as a kind of two-dimensional nanomaterial has aroused people’s strong research interest because of its excellent properties. In the present study, we introduced a new poly(vinyl alcohol)/poly(acrylic acid)/Fe3O4/MXene@Ag nanoparticle composite film fabricated by electrospinning and heat treatment as well as self-reduction reaction process. The obtained composite films showed high self-reduction ability because of the incorporation of MXene flakes. The intercalated MXene flakes in the compo...

Palladium-based bimetallic nanoparticles (NPs) have been studied as important electrocatalysts for energy conversion due to their high electrocatalytic performance and the less usage of the noble metal. Herein, well-dispersed PdAg NPs with uniform size were prepared via oil bath accompanied with the hydrothermal method. The variation of the Ag content in PdAg NPs changed the lattice constant of the face-centered cubic alloy nanostructures continuously. The Pd/Ag molar ratio in the PdAg alloy NPs...
