From macropore to mesopore: diatomite reassembled into a multifunctional composite†
Abstract
A ‘dissolving first and then reassembling’ way was presented for preparing a multifunctional composite with diatomite and an antistatic agent SN. The composite binding of SN@SiO2 with a sulfonic dye formed the color antistatic agent. Also, it captured nonylphenol from wastewater with a partition coefficient of 5.37 × 104 L kg−1, and the waste sludge produced was calcined to form mesoporous sieves.
