چکیده
Mass transfer and catalyst recovery are two crucial issues in solid base catalysis, while the cumbersome operation steps associated time energy penalties still inevitable for conventional catalysts. Achieving technical upgrades through design is desirable but challenging because of difficulty satisfying diverse demands different steps. In this work, a magnetically responsive with rod-like nanostructure was developed. The catalysts composed Fe3O4 cores, silica shells calcium oxide active sites. functions magnetic stirring were integrated into catalyst, which applies both general catalytic processes microchannel reactors given their nanoscales. When applied to synthesis dimethyl carbonate by one-step transesterification methanol ethylene carbonate, an apparent enhancement on turnover frequency value (33.1 h?1) observed nano-stirring compared that tested without (12.1 within 30 min. present may open up new avenues development advanced

Spindle-shaped nanoscale yolk/shell magnetic stirring bars for heterogeneous catalysis in macro- and microscopic systems.
A new type of spindle-shaped nanoscale yolk/shell magnetic stirring bar containing noble metal nanoparticles was prepared. The as-synthesized Pd-Fe@meso-SiO2 not only showed impressive activity and stability as a heterogeneous catalyst in a macroscopic flask system, but also acted as an efficient nanoscale magnetic stir bar in a microscopic droplet system.

متن کاملMultifunctional Catalysts for Singlewall Carbon Nanotube Synthesis
Single-wall carbon nanotubes (SWNTs) are usually produced with the help of metal catalysts that first break down various carbon species such as graphite, carbon clusters, amorphous carbon, or hydrocarbons and then release them in the form of SWNTs. These catalysts therefore must perform several functions in order to produce high quality, high yield, long SWNTs, and the finesse of these catalyst...
متن کاملActive Sites and Mechanism for the Water-Gas Shift Reaction on Metal and Metal/Oxide Catalysts
Current industrial catalysts for the water-gas shift reaction are commonly mixtures of Fe-Cr and Zn-Al-Cu oxides, used at temperatures between 350-500oC and 180250oC, respectively. These oxide catalysts are pyrophoric and normally require lengthy and complex activation steps before usage. Improved catalysts are being sought, particularly for lower temperature (e.g., at T<150oC, equilibrium lowe...
