Synthesis of Metal-Free Nanoporous Carbon with Few- Layer Graphene Electrocatalyst for Electrochemical NO2

摘要

Herein, electrochemical oxidation of nitrite (NO2-) is demon- strated using metal-free and electrochemically highly stable nanoporous carbon (NC) system. The surface features of nanoporous carbon were studied using both spectroscopic and microscopic techniques including scanning electron micro- scope (SEM), transmission electron microscope (TEM) and is having layered mesh-like features with a particle size of ～20 to ～100 nm.
