A highly recyclable dip-catalyst produced from palladium nanoparticle-embedded bacterial cellulose and plant fibers

Abstract

Bacterial cellulose loaded with palladium was fabricated into a sheet-like dip-catalyst through compositing with plant fibers.

Pd nanoparticles on green support as dip-catalyst: a facile transfer hydrogenation of olefins and N-heteroarenes in water

“…In this context, a new concept of "dip-catalyst" has emerged in order to achieve better efficiency, high turnover frequency (TOF), ease of fabrication, higher reusability and greener synthesis routes. 36,37 The term "dip-catalyst" refers to the convenient deployment, high recyclability, easy insertion/ removal which can turn the reaction on/off almost instantaneously. The area of "dip-catalysis" has remained largely unexplored.…”

‘Dip Catalysts’ Based on Polymer‐Metal Nanocomposite Thin Films: Combining Soft‐Chemical Fabrication with Efficient Application and Monitoring

“…Pd‐cellulose acetate films were formed by adding Pd nanoparticles to cellulose acetate solution and spreading on glass plate; the catalytic activity and recyclability of these films were demonstrated in 4‐nitrophenol reduction. Recently, Pd nanoparticles embedded in bacterial cellulose (BC) were synthesized using BC modified with poly(ethylene imine) . The nanocomposite fabricated using a standard sheet former was used as a ‘dip catalyst’ for the Suzuki‐Miyaura reaction; the highest TOF observed was 84–261 h −1 and the catalyst was recycled 26 times.…”

Synthesis of Quinazoline Derivatives Catalyzed by a New Efficient Reusable Nanomagnetic Catalyst Supported with Functionalized Piperidinium Benzene‐1,3‐Disulfonate Ionic Liquid

“…In MCRs catalyst plays an important role by altering the required activation energy. Generally homogeneous catalysts exhibit high catalytic activity than heterogeneous catalysts because of their molecular level dispersions …”
