Efficient Pt-free electrocatalyst for oxygen reduction reaction: Highly ordered mesoporous N and S co-doped carbon with saccharin as single-source molecular precursor
(2016)Despite that nitrogen (N) and sulfur (S) co-doped ordered mesoporous carbon (OMC) as Pt-free catalyst for oxygen reduction reaction (ORR) shows a desirable performance, the synthesis method is always complicated and ... -
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 ... -
Highly effective oxygen reduction reaction electrocatalysis: Nitrogen-doped hierarchically mesoporous carbon derived from interpenetrated nonporous metal-organic frameworks
(2017)Nitrogen-doped carbon materials with hierarchically mesoporous structure are synthesized in the present work via the pyrolysis of an interpenetrated non-porous metal-organic framework (MOF), viz. [Zn2(TPT)(BDC)2]·H2O ... -
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 ... -
Mesoporous IrNiTa metal glass ribbon as a superior self-standing bifunctional catalyst for water electrolysis
(2022)Metallic glasses (MGs) only show single activity for water electrolysis and rarely show superior bifunctional activity for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). In this work, IrNiTa ... -
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 ... -
Nitrogen-doped ordered mesoporous carbon: synthesis and active sites for electrocatalysis of oxygen reduction reaction

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 ... -
Preparation of graphitic mesoporous carbon for the simultaneous detection of hydroquinone and catechol
(2013)A graphitic mesoporous carbon (GMC) had been successfully synthesized using Ni-Fe layered double hydroxide (LDH) as both template and catalyst under a relatively low pyrolysis temperature. The techniques of X-ray diffraction, ... -
Synthesis of nitrogen-doped mesoporous carbon nanosheets for oxygen reduction electrocatalytic activity enhancement in acid and alkaline media
(2019)In the present work, nitrogen-doped mesoporous carbon nanosheets (NMCNs) are prepared and extensively investigated for the oxygen reduction reaction. Initially, by using dual templates, viz. graphene oxide and a cationic ...
