FeCu alloy dispersed N-doped carbon compound material for electrocatalytic naproxen degradation

The materials conventionally used for electrocatalysis in electrocatalytic Fenton applications are unstable and perform poorly. Based on the fact that iron and copper are common electrocatalytically active metals, they can provide abundant electron transfer capacity to facilitate electron transfer in the reaction and further promote the electrical conductivity of nitrogen-doped doped carbon materials Here, FeCu alloy/N-doped carbon composites (FeCu/N-C) are prepared for the electrocatalytic degradation of naproxen (NPX). Characterization results reveal that FeCu/N-C has more active sites, a larger surface area, and faster charge transport than N-doped carbon composites (N-C). Meanwhile, the increased number of active sites, surface area, and electron transport result in excellent NPX electrocatalytic degradation efficiency. The FeCu/N-C composite exhibits higher degradation efficiency than N-C under optimal conditions. In addition, the degradation efficiency is sustained at around 100% after five cycles. A detailed analysis of the mechanism reveals that 1 O 2 and ·OH are the primary active species responsible for NPX degradation through bursting studies. A potential pathway for the NPX degradation is proposed. This study provides a new and feasible method for developing carbon-based electrocatalysts to expand their applications in the environmental field.
