Morphological properties of reed straw and elephant grass by SEM imaging. a The external surface of reed straw (RS) without pretreatment (UP-RS) and with organosolv pretreatment (OP). And the EDS mapping of carbon and oxygen in reed straw after organosolv pretreatment. b The external surface of elephant grass (EG) without pretreatment (UP-EG) and with organosolv pretreatment (OP-EG) and alkali pretreatment (AP-EG)
