Efficient and recyclable palladium enriched magnetic nanocatalyst for reduction of toxic environmental pollutants

An efficient and sustainable Pd‐nanomagnetic heterogeneous catalyst for the reduction of nitroarene and environmental pollutant

“…61 In the next step, by electron transfer, the liberated H 2 reduces Cr(VI) on the catalyst surface. 6 After this step, the Pd-SB/MNP nanomagnetic catalyst's surface is ready for the next reduction cycle (Scheme 3).…”

“…As a solution to this problem, homogenous catalysts can be grafted onto the surface of organic or inorganic substrates as they contain free amino or hydroxy groups. [6][7][8] There are numerous supports that may be utilized as substrates, including dendrimers, polymers, zeolite, MCM-41, SBA-15, graphene oxide, chitosan, carbon nanotubes, magnetic nanoparticles, and others. [9][10][11][12][13][14][15][16][17][18] Iron oxide magnetic nanoparticles have shown great potential as a supporting material for metal catalysts.…”

Hydrothermal Microwave Synthesis of Co3O4/In2O3 Nanostructures for Photoelectrocatalytic Reduction of Cr(VI)

“…Moreover, the highresolution TEM (HRTEM) image of CI-5%−400 shows clear lattice fringes with an interval of 0.243 and 0.292 nm (Figure 3C), corresponding to the Co 3 O 4 (311) and In 2 O 3 (222) planes, respectively, 34,35 In addition, CI-5%−400 also exhibits highly crystalline and polycrystalline character (Figure S4C). 36 The chemical composition and elemental valence states of the catalysts were investigated through X-ray photoelectron spectroscopy (XPS) measurements. 37 The XPS full survey spectrum of CI-5%−400 is shown in Figure 4A, which shows the presence of Co, In, and O elements.…”

The synthesis and characterization of a magnetic histidine Schiff base palladium complex and its efficiency investigation in the nitroarene pollutants reduction and dyes degradation

“…Patil et al in 2020 designed a NHC-Pd (II) complex immobilized on graphene oxide for the reduction of nitrobenzene derivatives in aqueous methanol solvent at room temperature [16]. The Patil research group prepared NHC-Pd (II) complex anchored on Fe 3 O 4 nanoparticles for reduction of environmental pollutants [17] and also a magnetic Schiff base palladium (II) complex and investigated its efficiency in nitroarene reduction reaction using of NaBH 4 as reducing agent [18]. Recently, Xu et al prepared a Pd (II)-sulophen complex and immobilized it on the magnetic silica support.…”
