Highly effective palladium nanocatalyst supported in polymeric networks for the catalytic hydrogen generation from borane‐morpholine complex

Abstract

This study describes the synthesis of Pd 0 nanoparticles supported in hydrogel networks (SPVI@Pd) and their catalytic activity for the borane-morpholine complex (MB) hydrolysis reaction. In this respect, while our study is one of the limited number of studies reported for the catalytic hydrolysis of MB, it is the first study in which Pd 0 nanoparticles supported in hydrogel networks were used in the catalytic hydrolysis of MB. The synthesized Pd 0 nanoparticles were characterized using structural and morphological characterization techniques and as a result of these analyses, the sizes of Pd 0 nanoparticles were determined average as 7.01 � 1.90 nm. The E a value and the turnover frequency (TOF) value at 303 K for the SPVI@Pd 3.0 catalyzed MB hydrolysis reaction were determined as 49.46 kJ/ mol and 187.74 mol H2 ⋅ mol Pd À 1 ⋅ h À 1 . It was also observed that the SPVI@Pd 3.0 catalyst had good catalytic activity even after eight cycles.

Hydrogen Production from Morpholine−Borane by Aluminum Oxide‐Supported Pd Nanoparticles

“…In another recent study, Ozay et al. reported that SPVI@Pd nanocatalyst provided a TOF value of 187.8 h −1 (303 K) in the MB hydrolysis reaction [19] …”

“…Therefore, MB can be utilized as one of the most reliable chemical H 2 storage materials thanks to its advantages like relatively high H 2 content, low cost, and low toxicity [17] . MB, a white solid with a melting point of 371 K, has received much attention due to its high H 2 content (12 % by weight), which exceeds the Department of Energy's (DOE) 2023 target [18,19] . Although MB has these unique properties, only few studies on H 2 production from MB can be found in the literature [15] .…”

[18,19] Although MB has these unique properties, only few studies on H 2 production from MB can be found in the literature. [15] The first study on MB dehydrogenation was done by Metin et al (2019) [17] using Ag(0) and Pd(0) nanoparticles.…”

[19] (1) Herein, we present the facile preparation of Pd/Al 2 O 3 catalysts by a two-step impregnation-reduction method, [11] their characterization by advanced analytical techniques (ICP-OES, P-XRD, SEM, SEM-EDX, TEM, TEM-EDX, and XPS), and their utilization as catalysis for H 2 production from MB at room temperature.…”

Investigation of Drug Release Behavior of Cyclomatrix Polyphosphazene Microparticles Decorated with Gold and Silver Nanoparticles

“…For this reason, synthesis in the presence of any support material or stabilizing agent is generally preferred to preserve nanoscale properties. [8] Inorganic oxides, [9,10] fly-ash particles, [11] polymeric particles, [12] hydrogels [13][14][15][16][17] and water-soluble polymers [18] can be counted among the materials that are frequently preferred as stabilizer/ support materials in the synthesis of metallic nanoparticles. The most common metallic nanoparticles in nanobiotechnology are gold and silver nanoparticles.…”
