英文摘要	Aiming to monitor hydrogen peroxide and oxidizing ions in aqueous circumstance, functionalized attapulgite [i.e. gold-modified attapulgite nanocomposites (au/atp ncs)] as peroxidase mimics were prepared by loading beta-cysteamine-capped gold nanoparticles onto attapulgite with the use of electrostatic interactions. as-prepared au/atp ncs were used for the detection of h2o2. the linear range and detection limit for h2o2 were determined by quantitative experiments emerging excellent stability and recyclability. the peroxidase-like activity of au/atp ncs could be expanded for the detection of some oxidative ions (fe3+ and ag+) was also been discovered. based on the absorption spectrum and steady-state kinetics, the mechanism for peroxidase mimic reaction is investigated. this work represents the first example of multitarget detection for molecule and cations (h2o2, fe3+ and ag+) using au/atp ncs as peroxidase enzyme mimics and holds a promise for future biomedical and analytical applications.
