“…The magnetic properties of the designed Co(II)@2-BPy@ APTES@MHNTs allow for facile recovery and reusability for multiple times, making it a promising approach for wastewater treatment. 188 A CoFe 2 O 4 @HNTs/AuNPs composite was developed for the quick and efficient detection of aromatic amines and nitrofuran in real samples using magnetic solid-phase extraction (MSPE) surface-enhanced Raman scattering (SERS). Magnetic CoFe 2 O 4 beads inside halloysite nanotubes (HNTs) avoid particle aggregation and allow for rapid magnetic separation, and the outer surface was coated with gold nanoparticles (AuNPs) which enhance Raman signals and increase sensitivity.…”

Halloysite nanotubes (HNTs) have emerged as one of the promising clay minerals that have myriad applications due to their unique properties. The presence of silica and alumina groups on the outer and inner surfaces allows surface modifications with different functional compounds. Depending on the applications required, numerous desired compounds have been used for both inner and outer surface modifications to construct hybrid noanostructures which further enhance their physiochemical properties. This review discusses the surface design with special emphasis on magnetic nanoparticles to fabricate HNT-based magnetic nanostructures which display synergistic effects and summarizes potential applications in the fields of catalysis, magnetically driven drug delivery, chemotherapy/diagnosis, environmental remediation, emulsification, and microwave absorption.

Magnetic halloysite nanotubes based organic-inorganic hybrid materials have elicited ripples of excitement in the area of water research and technology by the virtue of their hollow nanotubular structure, presence of adequate hydroxyl groups and tunable surface chemistry. Fascinated by these riveting benefits, a nickel based nanocatalyst has been designed wherein a bidentate chelating ligand "4-aminoantipyrine (AA)" was anchored onto the surface of aminosilane functionalized magnetic halloysite nanotubes followed by its metalation. In a shorter time span of 30 min, the synthesized nanocatalyst showed outstanding degradation efficiency of 96.87 % and 96.22 % towards MV6B and AO7 respectively under neutral conditions. The ensuing nanocomposite in-situ generates * OH from H 2 O 2 that aided in rapid degradation of MV6B and AO7 into innocuous products with unprecedented efficacy. Besides, the impressive magnetic attributes of designed Ni(II)-@AA@APTES@MHNTs offer effortless magnetic retrievability with the aid of an external magnet and the catalyst could be recycled upto six consecutive runs. GC-MS analysis helped in identifying the generated degradation products and provided valuable insights into the plausible degradation pathway of pollutants followed during the reaction. Through various studies, it is believed that the peerless advantages of Ni(II)-@AA@APTES@MHNTs nanocatalyst will lay a foundation for treatment of wastewater containing devastating organic contaminants.
