In this report, with a traditional FTS catalyst of 10 wt% Co/SiO2 as core catalysts, we present two methods for H-ZSM-5 zeolite capsule catalyst preparation.
The chemistry presented for designing and synthesizing core catalyst structures optimized for stability and catalytic activity, are amenable to the construction of complexes that have pendant functionality; for example, alcohols, amines, amides, esters, acids, etc.
Thin film planar models of core-shell catalysts for the oxygen reduction reaction in PEM fuel cells, have been synthesised with tin doped titania as the support for platinum.
A zeolite capsule catalyst Cr/ZnO S Z was prepared successfully by a novel dual-layer method, in which one layer of neutral Silicalite-1 zeolite shell was first synthesized on the bimetallic Cr/ZnO core catalyst, acting as the intermediate layer for the following H-type H-ZSM-5 zeolite shell direct synthesis on its surface.
First, the performance advantages of Pt-based core-shell nanostrucatalyststalysts for the ORR (occurring at the fuel cell cathode) in acidic media is explored.
Core-shell structured Ru@Pd/C catalysts for the electrooxidation of formic acid are synthesized by an organic colloid method associated with a pulse electrodeposition process.
Here, we report on a novel hierarchical Cu@CoFe layered double hydroxide (LDH) core-shell nanostructure catalyst for efficient overall water splitting in the alkaline medium.
Our rational design of the hierarchical core-shell nanoarchitectures presents a simple approach to fabricate advanced catalysts for water splitting.
This appears to suggest the formation of a disordered Pt3Co core for these catalysts.
These findings will provide helpful guidance for design and fabrication of carbon-supported core shell catalysts for ORR in the future.
The present results suggest that stable core shell catalysts for PEMFC with Pt shell should be designed such that the shell is under a tensile stress (or reduced compression compared to monolithic catalyst particles).
