Summary: This study explores the formation mechanism of Ni-Al layered double hydroxide (NiAl-LDH) synthesized by coprecipitation. Furthermore, NiAl-LDH is prepared in a rotating packed bed (RPB) under different rotation speeds, and results show that increasing the rotation speed decreases the lateral size and thickness of NiAl-LDH due to accelerated nucleation. Additionally, the Ni/mixed metal oxides (MMO) catalysts derived from NiAl-LDH exhibit higher MA conversion with larger surface area and smaller nickel particle size.

Summary: This study investigated the performance of two types of LDH materials for the removal of PFAS, finding that Zn-Al LDH showed higher efficiency and better adsorption capacity for PFOA compared to Mg-Al LDH. The presence of natural organic matter had minimal impact on PFOA removal by Zn-Al LDH, while sulfate severely inhibited PFOA adsorption, suggesting that electrostatic interactions may play a primary role in the adsorption mechanism onto LDHs for PFAS removal.
