Catalytically active (Pd) nanoparticles supported by electrospun PIM-1: Influence of the sorption capacity of the polymer tested in the reduction of some aromatic nitro compounds

Electrospinning of uniform nanofibers of Polymers of Intrinsic Microporosity (PIM-1): The influence of solution conductivity and relative humidity

“…The electrospinning of PIM-1 fibers has been reported by different research groups for their use in water treatment for the scavenging of dyes [15,16], energy storage [17], volatile organic compounds [13] and nitrophenol reduction [18]. PIM-1 could successfully be electrospun from its solution in 1,1,2,2-tetrachloroethane (TeCA), which led to the bead-free microfibers of PIM-1 [15,[17][18][19].…”

PIM-1 could successfully be electrospun from its solution in 1,1,2,2-tetrachloroethane (TeCA), which led to the bead-free microfibers of PIM-1 [15,[17][18][19]. On the other hand, the solutions of PIM-1 in TeCA have very low conductivity, and therefore, the electrospinning of PIM-1 solutions requires a relatively high concentration to eject a single continuous fiber [13].…”

Hydrogen Peroxide Versus Hydrogen Generation at Bipolar Pd/Au Nano-catalysts Grown into an Intrinsically Microporous Polyamine (PIM-EA-TB)

“…Immobilisation of Pd nanoparticles into microporous hosts is linked to enhanced catalytic reactivity as long as (i) host-guest interactions do not cause blocking and (ii) permeation of reactants into the host is effective. There is one previous report on the immobilisation of Pd nanoparticle catalysts into the polymer of intrinsic microporosity (abbreviated PIM) PIM-1 [12]. Fibrous PIM-1 with Pd nanoparticles embedded were obtained by electrospinning and employed in the catalytic reduction of nitroaromatics.…”

Enhanced catalytic activity of natural hematite-supported ppm levels of Pd in nitroarenes reduction

“…One of the eicient methods for the removal of nitro compounds is the reduction of them to the corresponding amines, which are versatile precursors in organic synthesis as well as in the preparation of various compounds such as pharmaceuticals and agrochemicals [8][9][10][11]. In recent years, catalytic hydrogenation of nitroaromatic compounds employing different noble transition metals such as Pd [12][13][14] and Au [15][16][17][18][19][20][21][22] was investigated well. Moreover, cheap alternative metals such as Fe [23][24][25][26][27][28][29][30][31][32], Zn [33][34][35][36][37][38], and Sn [39,40] have been widely used for reduction of nitro group.…”
