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.
“…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.…”
Uneven arrangement of pores and poor electrolyte affinity of separators made from polyolefins or poly(vinylidene difluoride) result in disordered Li+ flux and rugged deposition layers, triggering continuous consumption of lithium...

“…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.…”
