Preparation Of Nanocatalytic Array And Nano Infrared Source By Electron Beam Lithography

The platinum nanoparticles with diameter of 50 nm had been successfully prepared on the surface of alumina by electron beam lithography.These nanoparticles acted as catalysts for catalytic combustion of methanol.In this work,we used SEM and AFM to characterize the morphology of the catalyst.At the same time,we characterized the catalytic performance of the catalyst by infrared microscopy and gas chromatography.We found that the catalyst prepared by this method had better catalytic activity and it can improve the energy conversion efficiency and methanol conversion.Then we found some factors would affect the catalytic performance of the catalyst.By exploring these factors,the catalytic performance of the catalyst can be improved.After that,we detected the infrared radiation during the reaction by an infrared CCD camera,then we simulated the light-gathering effects of the structure through FDTD simulations.The results show that the wavelength of infrared radiation will change when the reaction begins,and a specific periodic catalytic column can be used as a photonic crystal structure to concentrate and frequency the infrared light.So that the infrared light emitted by itself can be converged and emitted by a specific design.And then the nanoscale artificial light sources and the self-emitting photonic crystal light source can be prepared.
