Engineering of new hydrogel beads based conducting polymers: Metal-free catalysis for highly organic pollutants degradation

نویسندگان

چکیده

Engineering of new heterogeneous metal-free catalysts is great importance for persulfate activation. Herein, Innovative conductive polymers Polyaniline (PANI) and Polypyrrole (PPy) were used as promising PS activation to effectively degrade organic pollutants. In fact, PANI PPy can provide the necessary electron transfer based on nitrogen atoms located in conjugated chains compared their counterparts defective sites. addition, immobilized inside membrane formed by cross linking alginate biopolymer divalent calcium ions, order develop a stable hydrogel beads catalyst. The prepared hydrogels-activated process could maintain excellent catalytic properties, mitigate deactivation, increased chemical stability offer hope application industrial scale. radical scavenging experiments monitored paramagnetic resonance functional theory calculations, indicated role nature reaction pathways.

Solitonic States in Organic Conducting Polymers

In a typical solitonic distribution, the soliton density is distributed over the entire moleculeand the present work shows how its density can be decomposed into solitonic and antisolitoniccomponents. It is found that there exists a unique electron as soliton over the anionicnanoconductor, while there are many other solitons and antisolitons. The solitonic states are furtherdecomposed to the ca...

Metal-insulator transition in highly conducting oriented polymers

We suggest that highly conducting oriented polymers with a fibril structure can be modeled by a regular lattice of disordered metallic wires with a random first-neighbor interwire coupling which mimics the cross-links between fibrils. We show that such a model can be described by a non-linear sigma model. Within a one-loop self-consistent approximation, we determine the position of the metal-in...
