FTIR spectra of silica-NWs of K/A and K/R (12 months old) before and after heating up to 1000 °C. a before heating, b after heating for 1 h. Bands arising from H–bonding, and Amide I began to diminish, and some bands of Si–OR were visibly diminished after heating up to 1000 °C. Electron micrographs showing some examples of silica-NWs c before heating and d after heating, showing large glass like structures
