Ordered mesoporous carbons as highly active catalysts for hydrogen production by CH(4) decomposition.

New route toward building active ruthenium nanoparticles on ordered mesoporous carbons with extremely high stability

Creating highly active and stable metal catalysts is a persistent goal in the field of heterogeneous catalysis. However, a real catalyst can rarely achieve both of these qualities simultaneously due to limitations in the design of the active site and support. One method to circumvent this problem is to fabricate firmly attached metal species onto the voids of a mesoporous support formed simulta...

Design and Preparation of Electrocatalysts Based on Ordered Mesoporous Carbons for Oxygen Reduction Reaction

The research presented in this dissertation is aimed at the development of electrocatalysts for the oxygen reduction reaction (ORR) based on ordered mesoporous carbons (OMCs). The ORR is a key reaction in electrochemical energy devices such as fuel cells and metal-air batteries. Because of its sluggish kinetics compared to its counterpart reaction (i.e., hydrogen oxidation reaction in fuel cell...

CO x Free Hydrogen Production by Catalytic Decomposition of Methane Over Porous Ni/Al2O3 Catalysts

Three-dimensional ordered mesoporous Co3O4 enhanced by Pd for oxygen evolution reaction

Considerable efforts have been devoted recently to design and fabrication of high performance and low cost electrocatalysts for oxygen evolution reaction (OER). However, catalytic activity of current electrocatalysts is usually restricted by high onset potential and limited active sites. Herein, we fabricated three-dimensional (3D) highly ordered mesoporous Pd-Co3O4 composite materials as excel...

Effect of Silica Content on Support-Iridium Active Phase Interactions on the Nanocatalyst Activity

To discuss the potential role of the support for iridium catalyst, we have proceeded to prepare a series of supported catalysts with the same active phase content, but different silica content, to elucidate the changes in surface structure and the reaction process of hydrous hydrazine decomposition on catalyst. The obtained iridium catalysts contained 20 wt% of nanoparticles dispersed on spheri...
