    Abstract

    © 2018 Elsevier Inc. An N-doped carbon nanofiber cloth (CC) with anchored nickel nanoparticles (Ni@N-CC) was synthesized from a facile pyrolysis process and employed as a catalyst to oxidize target contaminants using peroxydisulfate (PDS) as both radical precursors and electron acceptors. An effective strategy was developed to control the porous structures and catalytic performances by optimizing the precursor weights and pyrolysis temperatures for Ni@N-CC preparation. The optimal temperature was 700 °C, and the best dicyanodiamine mass was 1.0 g. Ni@N-CC was found to be superior for PDS activation to CC and nickel nanoparticles (NPs), ascribing to highly active sites, intimate connection between the nickel NPs and highly conductive N-doped CC, as well as the formed three-dimensional architecture. The oxidation rates were influenced by the oxidant loading (0.185–1.11 mM), initial organics concentration (10–50 mg/L), temperature (5–45 °C), pH (2.65–10.47), and inorganic anions. Furthermore, mechanistic investigations using various probe reagents and spin trapping technique identified the generation of several active species for oxidation. The reaction was found to proceed via the electron transfer mediation from organics to PDS on N-doped CC and one electron reduction of PDS on Ni 0 NPs. This study highlights the design of highly active and reusable heterogeneous carbon/metal hybrids for more efficient PDS activation in environmental remediation.
