Ultrahigh Sensing Performance: Coresponse and Differentiation of Ethyl Acetate and Its Byproducts in Fe–Ce–O Interfacial Sensor

ACS Sensors, Год журнала: 2025, Номер unknown

Опубликована: Март 6, 2025

Accurately detecting low concentrations of ethyl acetate (EA) holds promise for the early screening rectal and gastric cancer. The primary challenges lie in achieving a high response at parts per billion level concentration ensuring selectivity. This study focuses on designing Fe-Ce-O bimetallic oxides with doping heterogeneous interfaces, which exhibit outstanding redox properties highly enhanced ability adsorption activation both O2 EA molecules. Benefiting from violent reaction between adsorbed oxygen species, sensor achieves an ultrahigh sensing more than 500,000 200 ppm concentration, along ultrafast recovery rate (<5 s). In experiments, can reach 4.8 even extremely 10 ppb. Special attention is given to interfacial chemical reactions through situ DRIFTS during process. We propose first time that produced intermediate byproducts (acetaldehyde, alcohol, acetic acid, formic acid) coresponse this sensor, contributing its response. Furthermore, are effectively classified using linear discriminant analysis 95% accuracy. work expected elucidate mechanisms, particularly contributions derived sensor's response, novel idea high-performance sensors.

In situ Production of Hydroxyl Radicals via Three‐Electron Oxygen Reduction: Opportunities for Water Treatment

Angewandte Chemie, Год журнала: 2024, Номер 136(40)

Опубликована: Июль 15, 2024

Abstract The electro‐Fenton (EF) process is an advanced oxidation technology with significant potential; however, it limited by two steps: generation and activation of H 2 O . In contrast to the production via electrochemical two‐electron oxygen reduction reaction (ORR), three‐electron (3e − ) ORR can directly activate molecular yield hydroxyl radical (⋅OH), thus breaking through conceptual operational limitations traditional EF reaction. Therefore, 3e a vital for efficiently producing ⋅OH in situ, charting new path toward development green water‐treatment technologies. This review summarizes characteristics mechanisms ORR, focusing on basic principles latest progress situ efficient utilization modulation pathway, shedding light rational design catalysts, mechanistic exploration, practical applications water treatment. Finally, future developments challenges efficient, stable, large‐scale are discussed based achieving optimal regulation potential combine other
