Research Of Fenton Catalytic Sensor Based C₆₀@au Nanoplasma

With the development of the times, to seven in twentieth Century, the problem of environmental pollution is becoming more and more obvious, especially,the pollution of water has become a worldwide problem, and difficult to degrade organic substances of water pollution in how to deal with the water pollution treatment is more important in the problem. Due to the shortage of natural water resources, the development of the industry produced large amounts of wastewater, therefore,we need a effective method to treatment industrial wastewater. At this time, chemists have found that Fenton reagent,which has been forgotten for nearly half a century, has its characteristics to the degradation of these organic pollutants. So far, Fenton application report of catalytic reaction as the degradation of organic matter has sprung up, and its application is constantly expanding, the corresponding research has been deepened.The optical indirect nanoplasmonic sensing(INPS) concept was first presented in 2009. The INPS spectroscopy platform utilizes the LSPR excitation in either individual or an array of plasmonic gold sensor particles at visible light frequencies to study processes and changes on/in adjacent nanomaterials. As the key novel ingredient to facilitating the use of LSPR-based sensors in highly demanding environments and allowing for almost infinite material combinations. It is precisely because of these unique properties, so INPS technology play a crucial role in the catalytic reaction monitoring field.The nano plasma, which was stimulated by metal nanometer structure under optical excitation, has excellent catalytic activity to the redox reaction on the surface and exhibits high sensitivity of the optical sensing to the electrons of the surface. In this paper, we present that prepared a new nano plasma catalytic sensor by combination of the catalytic activity of the sensing properties of the nano plasma and applied to the in situ spectroscopic monitoring on the catalytic reaction or the trace detection of the small organic molecules. As a representative,we describe a new type of Fenton catalytic sensor based on gold nanoparticles and fullerene. Subsequently,we proved the activity of the composite to the Fenton reaction and the sensing properties for sensor. After all above,we established a monitoring system for in situ spectrum sensor. Especially, we innovative proposed that using the rock frequency of the LSPR-peak for the process of the Fenton reaction. The key feature of this system is the use of plasmonic rock frequency, leading to a highly accurate and sensitive sensing of micro level of organics with a background signal of zero.
