Biotechnological synthesis of Pd-based nanoparticle catalysts

Abstract

Cell supported Pd metal nanoparticles are sustainably synthesised via microbial bioreduction. Bio-Pd nanoparticles are effective heterogeneous catalysts that catalyse industrially important reactions, such as hydrogenation and C–C coupling reactions.

Reduction Kinetic of Water Soluble Metal Salts by Geobacter sulfurreducens: Fe2+/Hemes Stabilize and Regulate Electron Flux Rates

“…Geobacter sulfurreducens has found important applications in remediation of oxidizing and toxic metal salts (Lovley et al, 2011;Pushkar et al, 2021), as an electron source of microbial fuel cells (Bond and Lovley, 2003;Slate et al, 2019), as well as a reagent for the synthesis of nanoparticles (Lloyd et al, 2011;Khan et al, 2020;Egan-Morriss et al, 2022). This microorganism, first discovered and isolated by Lovley et al (1987) and Caccavo et al (1994) relies on different extracellular minerals (Lovley and Phillips, 1988;Shi et al, 2016) and metal salts as electron acceptors (Ding et al, 2008;Lloyd et al, 2011;Lovley et al, 2011;Levar et al, 2014).…”

Pd nanoparticles decorated ultrathin 2D metal–organic framework nanosheets with enhanced peroxidase–mimic activity and colorimetric assay of glucose

“…Typically, 40 mL of TMB (5.0 mg mL −1 ) and 40 mL of H 2 O 2 (5.0 mM) were added in 870 mL of sodium acetate buffer (0.2 M, pH 4.0) in the presence of Pd@Cu-TCPP(Fe) (50 mL, 1.0 mg mL −1 ). The pH-dependent catalytic activity was measured in different reaction buffers (pH 2.4, 3.2, 4.0, 4.5, 5.2, 6.0, 7.0) at 55 °C, while temperaturedependent activity was measured in sodium acetate buffer (0.2 M, pH 4.0) at different temperatures (20,25,30,37,45,55,60, 70 °C). The time-dependent activity was assayed by conducting reaction for 2-10 min, respectively.…”
