The release of azo dye contaminants from textile industries into the environment is an issue major concern. Nanoscale zerovalent iron (nZVI) has been extensively studied in degradation pollutants such as methyl orange (MO). In this study, was coupled with copper and silver to make trimetallic Fe/Cu/Ag nanoparticles, order enhance MO increase reactivity catalyst by delaying rate oxidation iron. ...

Abstract Pt‐based alloy catalysts supported on carbon are commonly characterized for oxygen reduction reaction (ORR) activity using the rotating disk electrode technique (RDE). Within this study, we show exemplarily PtNiMo/C that applied pretreatment influences strongly determined activity. The classically employed descriptor of unchanged cyclic voltammetry response is insufficient to portrait ...

Photocatalytic CO 2 reduction is a highly vital process for converting into valuable chemicals.

An electrochemical sensor based on AuPtPd trimetallic nanoparticles functionalized multi-walled carbon nanotubes coupled with chitosan modified glassy electrode (GCE/CS/MWCNTs-AuPtPd) was proposed for the rapid detection of bisphenol A (BPA). were first assembled MWCNTs to obtain MWCNTs-AuPtPd nanocomposite. Then, further dispersed chitosan-modified surface fabricate GCE/CS/MWCNTs-AuPtPd sensor...
