2D nitrogen-doped hierarchically porous carbon: Key role of low dimensional structure in favoring electrocatalysis and mass transfer for oxygen reduction reaction
(2017)An ultrathin (thickness 1.0 nm) 2D nitrogen-doped hierarchically porous carbon (2DNHPC) film is developed by the nanocasting method; for comparison, a 3D nitrogen-doped ordered mesoporous carbon (3DNOMC) is also synthesized. ... -
A facile soft-template synthesis of ordered mesoporous carbon/tungsten carbide composites with high surface area for methanol electrooxidation
(2012)Ordered 2D hexagonal mesoporous carbon/tungsten carbide (OMC/WC) composite nanomaterials have been successfully synthesized for the first time by the soft-template method with ammonium metagungstate as tungsten precursor ... -
An investigation of WC stability during the preparation of Pt@WC/OMC via a pulse microwave assisted polyol method
(2015)In the present work, the WC stability during the preparation of Pt@WC/OMC (Ordered Mesoporous Carbon) electrocatalysts, through a pulse microwave-assisted polyol method, is investigated by the aid of X-ray diffraction and ... -
Iron oxide@graphitic carbon core-shell nanoparticles embedded in ordered mesoporous N-doped carbon matrix as an efficient cathode catalyst for PEMFC
(2020)Developing electrocatalysts with high activity and long-term stability towards oxygen reduction reaction (ORR) in acidic media is still an important topic. However, most of the already reported non-precious-metal catalysts ... -
Nitrogen-doped 3D hierarchical ordered mesoporous carbon supported palladium electrocatalyst for the simultaneous detection of ascorbic acid, dopamine, and glucose
(2019)In the present work, nitrogen-doped three-dimensional (3D) hierarchical ordered mesoporous carbon supported palladium (Pd 20 wt%/N-3D) electrocatalyst was successfully synthesized with the nanocasting method. The as-prepared ... -
A novel sulfur-nitrogen dual doped ordered mesoporous carbon electrocatalyst for efficient oxygen reduction reaction
(2016)Despite nitrogen doped carbon (NC) materials as metal-free electrocatalysts for oxygen reduction reaction (ORR) have shown desirable performance, the state-of-the-art of NC materials is still far from satisfaction for ... -
Ordered mesoporous tungsten carbide/carbon composites promoted Pt catalyst with high activity and stability for methanol electrooxidation
(2014)The current anode materials used for direct methanol fuel cells (DMFCs) are expensive and not sufficiently durable for commercial development. One of the major challenges lies in the development of an inexpensive, efficient ... -
Pt/CN-doped electrocatalysts: Superior electrocatalytic activity for methanol oxidation reaction and mechanistic insight into interfacial enhancement
(2017)Nitrogen-doped ordered mesoporous carbon (NOMC) is studied as the support to synthesize a Pt/CN-doped catalyst for methanol oxidation reaction (MOR). The effects of carbon dimension and metal loading are investigated by ...
