The sludge is pretreated to prepare the bicohar by pyrolysis, which divided into high-carbon biochar and high-ash using flotation. are used activated carbon, MgAl-layered double hydroxides (MgAl-LDO) ceramsite for Pb2+, methyl orange (MO) ciprofloxacin (CIP) removal from wastewater, respectively. carbon prepared ZnCl2 as chemical agent in additive of pine sawdust MO CIP with adsorption amount 754.05 mg/g 635.62 mg/g, Mg-Al LDO leaching solution bicohar, can quickly remove Pb2+ wastewater 147.89 mg/g. has good reusability after three cycles. MO/CIP mechanism analyzed investigated. residue also capacity 1.44 above results indicate that converted kinds adsorbents pollution realizing high value utilization sludge.

Silicon (Si) and Si-based compounds have been considered by many researchers as one of the anode materials for next-generation lithium-ion batteries (LIBs) due to their extraordinarily large theoretical capacity, moderate operating voltage, abundant resources. However, silicon's poor conductivity significant volume changes during charge discharge, compared conventional carbon materials, severely restrict its widespread use in LIBs. In this study, a two-dimensional (2D) mesoporous Si nanosheet/carbon (pSi@C) composite is designed using cetrimonium bromide–disodium edetate dihydrate (CTAB–EDTA) template via sol–gel method, magnesium thermal reduction decomposition method. The vertical diffusion distance Li+ significantly reduced 2D nanosheets. Additionally, coating on surface provides protective layer limit expansion form stable solid electrolyte interface (SEI). This enhances structural integrity cycle stability pSi@C material insertion extraction. At current density 1 A g–1, reversible capacity after 150 cycles 2236 mAh with retention rate 71.5%. electrode's 467.8 g–1 500 at 5 g–1. Therefore, unique technology can be used design composites excellent properties, thereby providing an effective strategy commercial application
