Raman spectroscopy is a fingerprint recognition and non-destructive molecular spectroscopy technique. Unlike infrared spectroscopy, Raman spectroscopy is not limited by water and air, and can obtain signals in low wavenumber regions. It can be used to analyze electrode surface reaction processes, and can identify hydroxyl groups, reactive oxygen species, metal carbon bonds, and metal oxides through its specific Raman peaks, Gradually becoming an important tool for analyzing electrode materials and interface reaction processes in fuel cells, especially the development of surface enhanced Raman spectroscopy (SERS) and shell isolation surface enhanced Raman spectroscopy (SHINERS), provides a very good in-situ spectroscopic experimental platform for studying trace intermediate species in reactions in fuel cells and understanding the actual reaction mechanism of fuel cells, which helps to design more efficient catalysts and electrode materials reasonably.

Raman spectroscopy has various applications in the field of energy, involving energy materials, energy conversion, and storage. Here are some typical application scenarios:

1. Energy material analysis: Raman spectroscopy can be used to analyze and characterize the structure and properties of energy materials. For example, for photovoltaic materials in solar cells, electrode materials or catalyst materials in energy storage materials, Raman spectroscopy scanning can be performed to understand the crystal structure, surface morphology, lattice defects and other information of the materials, thereby optimizing material design and performance tuning.

2. Fuel analysis: Raman spectroscopy can be used for fuel analysis and identification. By conducting Raman spectroscopy measurements on fuel samples, their composition and structural characteristics, such as chemical bonds and molecular vibration modes, can be determined. This helps to evaluate the quality, purity, and flammability of fuels, thereby guiding their development, selection, and use.

3.Energy conversion and storage research: Raman spectroscopy plays an important role in energy conversion and storage research. For example, in photocatalytic materials, analyzing the Raman spectra of the catalyst surface can reveal the mechanism of photocatalytic reactions, surface adsorption species, and reactive active sites, thereby improving catalytic efficiency. In batteries and energy storage devices, Raman spectroscopy can be used to analyze changes in electrode materials, interface reactions, and changes in electrolyte composition, which helps improve battery performance and cycling stability.

4. Biomass energy research: Raman spectroscopy has a wide range of applications in biomass energy research. By analyzing the Raman spectra of biomass samples, it is possible to understand the composition characteristics of biomass, the structural properties of cellulose and hemicellulose, and other information, thereby guiding the conversion and utilization process of biomass energy.
