Abstract The composition and structure evolution of carbon nanotube (CNT)/silica xerogel composites during the process of laser irradiation was traced by infrared (IR) spectra, Raman spectra, transmission electronic microscope (TEM) and pore structure analysis. The results of IR and Raman spectra show that during the process of laser irradiation the compositions of the composites do not make any noteworthy changes, while the matrix silica network becomes perfect and the doped CNTs become more graphitized. TEM images and pore structure analysis show that the SiO2 granules and the corresponding pore size increase after laser irradiation.
