From macropore to mesopore: diatomite reassembled into a multifunctional composite

Abstract

A ‘dissolving first and then reassembling’ way was presented for preparing an SN@SiO2 composite by the hybridization of an antistatic agent SN with diatomite. The colored antistatic agent was prepared by binding of the composite with a sulfonic dye. Also, it captured nonylphenol from wastewater, and the waste sludge produced was calcined to form mesoporous sieves.

A Li+-flux-homogenizing separator for long-term cycling of Li metal anodes

“…The Raman peak corresponding to the stretching vibration of the NO 3 À ion (1044 cm À1 ) and the FT-IR peaks arising from -CH 2 -(2921 cm À1 ) and -CH 3 (2850 cm À1 ) stretching vibrations confirm the successful integration of the SN into the PVDF-HFP polymer matrix. 42,43 Noticeably, the PVDF-HFP/ SN separator exhibits a higher fraction of b-phase PVDF after mixing with the SN, as evidenced by the increased intensity ratio of 840 cm À1 /804 cm À1 in its Raman spectrum and the prominent shoulder peak shown at 1271 cm À1 in the FT-IR spectrum. 44,45 Electrostatic potential (ESP) calculation for the (VDF) 3 -(HFP) 3 molecule (Fig.…”

BiOBr hybrids for organic pollutant removal by the combined treatments of adsorption and photocatalysis

“…This composite had high adsorption capacity and fast adsorption rate. 36 Based on the aforementioned consideration, a facile one step co-precipitation method was proposed to prepare lamella accumulational SiO 2 -BiOBr composite. It exhibited a highly superior photoactivity for the degradation of X3B in an aqueous system.…”
