Amino-Functionalized Hierarchical Porous Carbon Derived from Zeolitic Imidazolate Frameworks for Ultrasensitive Electrochemical Sensing of Heavy Metals in Water
Abstract:Electrochemical sensing provides a feasible avenue to
monitor heavy
metal ions (HMIs) in water, whereas the construction of highly sensitive
and selective sensors remains challenging. Herein, we fabricated a
novel amino-functionalized hierarchical porous carbon by the template-engaged
method using ZIF-8 as the precursor and polystyrene sphere as the
template, followed by carbonization and controllable chemical grafting
of amino groups for efficient electrochemical detection of HMIs in
water. The amino-function… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
