The Improved Cooperation of Metal–Acid Catalysis Using Encapsulation and P Doping Enhances the Preparation of 3-Acetyl-1-Propanol

Catalysts, Journal Year: 2025, Volume and Issue: 15(4), P. 390 - 390

Published: April 17, 2025

Biomass, as a renewable carbon resource, holds broad application prospects. Among various bio-based platform molecules, furan derivatives play significant role in green chemical production. Notably, the conversion of 2-methylfuran (2-MF) to 3-acetyl-1-propanol (3-AP) over bifunctional catalysts has attracted considerable interest. In this study, Pd@PHZSM-5 catalyst was prepared by encapsulating Pd nanoparticles within P-doped HZSM-5 for 2-MF conversion. The encapsulation improved dispersion and metal–acid synergy, enhancing both catalytic activity 3-AP selectivity. Additionally, phosphorus doping increased crystallinity, resulting excellent stability. This work provides feasible strategy optimizing cooperation, offering theoretical guidance catalysis biomass valorization.

Biomass energy is a kind of that can play an important supporting role in the future. In-situ hydrogenation biomass reduces consumption hydrogen and lowers cost production, so focus on in-situ bio-oils great green chemistry practical significance, which significantly reduce producing with high combustion performance to replace fossil fuels. In this paper, series nickel-modified molybdenum carbide catalysts (Ni-Mo x C) two crystalline phase structures simultaneously were prepared by one-step pyrolysis based organic-inorganic hybrid precursors. As-synthesized materials characterized XRD, XPS on. It was found synthesized exhibited good catalytic for hydrodeoxygenation phenol, conversion selectivity phenol cyclohexanol being 95.1% 93.4%, respectively, methanol water most supply media.

Phenotypic Diversity in Cell Wall Lignocellulosic Constituents and Ethanol Yield of USDA Guayule and Mariola Germplasm

Plants, Journal Year: 2025, Volume and Issue: 14(8), P. 1239 - 1239

Published: April 18, 2025

Guayule (Parthenium argentatum A. Gray) is a valuable domestic source for rubber and resin. At its center of origin in the Northern Mexico Southern Texas deserts, guayule, perennial shrub, hybridized with relative species mariola incanum Kunth). As resin are main products derived from there interest using guayule bagasse as bioenergy feedstock to meet growing biofuel demands. This study aimed explore characterize phenotypic diversity cell wall constituents (lignin, cellulose, hemicellulose) their yields among 51 genotypes under two irrigation regimes (well-watered water-stressed). Significant genotypic environmental effects were observed lignin, cellulose hemicellulose concentrations, yields, indicating wide genetic variability collection bioenergy-related traits. Moderate high entry-mean heritability values suggest that selection feasible enhance gain. positive correlations found concentrations possibility select multiple traits together during breeding cycles. High between highlight opportunity develop germplasm enhanced multi-use industrial applications. Wide variations drought stress indices (stress tolerance index, yield stability index) underscore impact on lignocellulosic Several identified index scores could be parental candidates improving arid semi-arid sustainable agricultural systems. The current first diversities components yield, providing foundation future efforts at enhancing guayule’s value diverse production goals conditions.

Stable RuIr Nanoalloy Catalyst for Levulinic Acid Hydrogenation Reaction

Molecules, Journal Year: 2024, Volume and Issue: 30(1), P. 93 - 93

Published: Dec. 29, 2024

Hydrogenation of levulinic acid (LA) represents a significant approach for producing the high-value biomass-based platform compound γ-valerolactone (GVL). In this study, an efficient RuIr alloy bimetallic catalyst supported on SiC was synthesized and applied aqueous hydrogenation LA into GVL under mild conditions. The RuIr/SiC exhibited high conversion selectivity (both > 99%) in water at 0.2 MPa H2 pressure 25 °C. excellent performance is attributed to synergistic interaction between Ru Ir nanoparticles semiconducting support. Furthermore, catalytic activity remained basically unchanged after five cycles, confirming stability catalyst.
