“…The selective oxidation of D-glucose into D-gluconic acid has been formerly described for HPS-Ru systems [21]. In the present study, these results are compared to those obtained on more conventional nanocatalysts prepared with Pd supported on zeolites.…”

“…Several methods are currently available for the oxidation of D-glucose, which serves as an intermediate in calcium gluconate synthesis. The direct selective catalytic route promises many advantages compared to other methods (chemical, electrochemical, biotechnological) [9][10][11][12][13][14][15][16][17][18][19][20][21]. Compared with chemical oxidation, the catalytic route avoids protecting and deprotecting the carbohydrate functional groups, two steps which result in a high loss of the target product.…”

In the present work, nanocatalysts prepared on inorganic supports (zeolites) were investigated in D-glucose oxidation and compared to systems supported on polymer (hypercrosslinked polystyrene (HPS)) previously described. Catalytic activities and selectivities were measured under various reaction conditions. The selectivity of D-glucose oxidation and activity of both Pd-containing zeolites and HPS-Ru were similar (99.7% and TOF 0.013-0.014 mol/(mol Me s)). Physicochemical analysis X-ray photoelectron spectroscopy, liquid nitrogen physisorption, diffuse reflectance infrared Fourier transform spectroscopy of adsorbed CO for metal sites evaluation, CD 3 CN for acid sites evaluation showed that Pd species were in oxidic form, while Ru species were in oxidic and reduced form. The catalytic activity decreased when acidic sites were present in Pd-containing zeolites.

“…In this case, the size of the growing particles can be limited to the cavity size [10]. Hypercrosslinked polymeric matrices are prospective organic supports for metal NPs synthesis and stabilization [11,12] due to the large specific surface area (usually near 1000 m 2 /g) and relative thermal stability [13]. Hypercrosslinked polystyrene (HPS) is the first representatives of such polymeric matrices [14].…”

This paper reports on ruthenium nanoparticles formation and stabilization by hypercrosslinked polystyrene and the catalytic properties of the nanocomposites obtained. Hypercrosslinked polystyrene with functional groups and without them was used. The nanocomposites were characterized using lowtemperature nitrogen physisorption, X-ray photoelectron spectroscopy and transmission electron microscopy. It is established that the tertiary amine group of the support influences both formation of ruthenium nanoparticles, and their catalytic properties in the selective hydrogenation of D-glucose.

This paper reports palladium (Pd)-containing nanoparticle (NP) formation in nanoporous hypercrosslinked polystyrene (HPS), using Pd acetate as a precursor. It was demonstrated that the NP size and composition can be controlled by Pd acetate loading and post-impregnation treatment with hydrogen gas. The catalyst structure was studied using transmission electron microscopy (TEM), X-ray fluorescence analysis, X-ray photoelectron spectroscopy (XPS) and nitrogen physisorption measurements. The catalytic properties of the catalysts developed have been studied in a green process of D-glucose oxidation to D-gluconic acid. The latter and its Ca salt are used for pharmaceuticals and food supplement production. The most active catalyst was found to contain 1.7 nm Pd/PdO NPs at 1.09 wt% Pd loading. It provided 99.6% selectivity at 93.6% conversion. Repeated use of the same catalyst demonstrated exceptional stability in D-glucose oxidation, making these catalysts promising for industrial applications in sustainable processes.
