a Digital photos of the fresh and dry leaves before and after CCT. Scale bar, 5 cm. b Micro-morphologies of char and element distribution maps for gelatin and FRS (scale bar, 100 μm), and the leaves (scale bar, 100 μm). c FTIR spectra of char. d FTIR spectra of volatiles at different temperatures. e Raman curves and full survey XPS data for the char. f High-resolution spectra.
