Progress in the application of electron paramagnetic resonance in fundamental chemical engineering research
Electron paramagnetic resonance(EPR)technology can be used to detect paramagnetic species such as free radicals,transition metal ions and defects.The spectrogram has high specificity and few background signals.It can detect both solution samples and solid samples with low detection limit.In chemical engineering field,especially in free radical related process,EPR technology has incomparable advantages compared with other spectroscopies.However,the EPR technology is not widely used by scientists in the chemical industry.Some examples of the application of EPR in chemical engineering field are reviewed,including the characterization of catalysts,reactive intermediate,solvent properties,and material properties.It is not a very comprehensive review,but rather to demonstrate the necessity and practicality of EPR technology in fundamental chemical industry research.It is hoped that chemical engineers can learn more about EPR and use EPR technology to solve more chemical engineering problems.
