Towards the design of efficient metal free ORR catalysts based on Zeolite Templated Carbons

Design of hierarchical zeolite catalysts by desilication

Active sites on graphene-based materials as metal-free catalysts.

Graphenes and related materials have attracted growing interest as metal-free catalysts. The present review is focused on describing the active sites that have been proposed to be responsible for the catalytic activity observed for such systems. It will be shown that diverse defects and chemical functionalities on the graphene layers can catalyze reactions, including oxygenated functional group...

Metal Templated Protein Interface Design

Despite having access to only a handful of metal coordinating groups, the ability of proteins to control and harness the reactivity of metal centers is unmatched in small molecule metal complexes. This is primarily due to the fact that the coordination and solvation environments of metals can be exquisitely tuned by the highly evolved non-covalent bonding networks of proteins that surround the ...

the role of task-based techniques on the acquisition of english language structures by the intermediate efl students

this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...

Synthesis and acid catalysis of zeolite-templated microporous carbons with SO3H groups.

Microporous carbon catalysts with large surface areas (800-1100 m(2) g(-1)) and high densities of SO3H groups (ca. 1.1 mmol g(-1)) were synthesized by sulfonation of zeolite-templated microporous carbon. The resulting SO3H-bearing microporous carbon catalysts exhibited higher catalytic performance for the hydrolysis of cellobiose and the Beckmann rearrangement than conventional solid acid catal...
