It is imperative to remove NO from exhausted gas, and electrochemical NH3 synthesis via N2 reduction still suffers from the low activity and low selectivity. It is of interest that...
An effective substrate for surface-enhanced fluorescence, which consists of cluster Ag/Au bimetallic nanostructures on a copper surface, was synthesized via a multi-stage galvanic replacement reaction of a Ag cluster in a chlorauric acid (HAuCl4) solution at room temperature. The fabricated silver/gold bimetallic cluster were found to yield large surface-enhanced fluorescence (SEF) enhancement factors for rhodamine 6G probe molecules deposited on the substrate, and also the fluorescence efficiency is critically dependent on the period of nanostructure growth. With the help of proper control reaction conditions, such as the reaction time, and concentration of reaction solutions, the maximum fluorescence enhanced effect was obtained. Therefore, the bimetallic nanostructure substrate also can be adapted to studies in SEF, which will expand the application of SEF.
In this work, Fe–BHT is identified as the most efficient catalyst for hydrogen evolution reaction (HER) among the TM–BHTs (TM = Sc, Ti, V, Cr, Mn, Fe, Co, Ni), with...
Developing high-efficiency and low-cost electrocatalysts for oxygen evolution reaction (OER) has been demanded in sustainable fuel production and energy storage. However, the inherent scaling relationship in conventional adsorbate evolution mechanism...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
