“…The catalytic activity of MC-Pd NPs and MC-FePd Theoretically, the pyrolysis temperature shapes the metal crystal's size, the state of dispersion, and the coupling of the metal crystals to the carbon, which regulates the catalytic properties of the desired material (Xiong et al 2015, Sytwu et al 2019, Tran et al 2022. Therefore, Pd/Fe loaded residue precursors were pyrolyzed at 500 °C, 700 °C and 800 °C, in addition to 600 °C.…”

“…Recently, mixing iron in the preparation of Pd nanoparticles is increasing since iron is more abundant and less expensive than palladium but similar in the periodic law of elements (Holland 2015, Qiao et al 2021. For instance, bimetallic Pd-Fe catalysts loaded with Al-MCM-41 showed higher hydrodeoxygenation yields and stability than monometallic catalysts in lignin-derived bio-oils (Tran et al 2022).…”

To obtain a magnetically separable, low-cost and highly efficient reduction catalyst, microbial carbon-loaded bimetallic palladium/iron nanoparticles (MC-FePd3 NPs) were synthesized in this study by using waste yeast residue doped with iron during the preparation process of microbial carbon-loaded monometallic palladium nanoparticles (MC-Pd NPs). The morphology, crystal structure, magnetic properties and catalytic performance of MC-FePd3 NPs for the reduction of p-nitrophenol (p-NP) were investigated by various characterization techniques, such as SEM-EDS, TEM, XRD, PPMS-9 and UV-vis spectroscopy. The catalytic experiments showed that the MC-FePd3 NPs prepared under pyrolysis conditions at 700℃ had an apparent rate constant of 1.85×10-1/s which is better than the rate constants of MC-Pd NPs and other palladium-based nanocatalytic materials reported so far. The amount of palladium used in the synthesis of MC-FePd3 NPs was half that of MC-Pd NPs. The catalyst exhibited soft magnetic ordering behavior and still showed a catalytic efficiency of 97.4% after five consecutive reaction cycles. Furthermore, employing MC-FePd3 NPs reduces the costs of catalyst preparation and use in production. MC-FePd3 NPs with efficient catalytic properties, facile magnetic separation and recyclability, and low costs of preparation and use have considerable potential for industrial applications.

“…The use of catalysts can improve the quality or yield of bio-oil by reducing the activation energy of the reaction. Pt, Pd, , and Ru have been widely used to upgrade bio-oil due to their antisintering ability and more acid sites. However, the application of these precious noble metals is hindered by their high costs.…”

Hydrothermal liquefaction (HTL) is one of the most promising technologies for biofuel production. The preparation and application of catalysts for HTL have been the research focus in recent years. In this study, a new synergistic catalytic process strategy is proposed. CuO−CeO 2 /γ-Al 2 O 3 was used as an in situ hydrogen donor catalyst and Ni−Co/SAPO-34 was synthesized for hydroprocessing to improve bio-oil production process. The results of XRD and XPS demonstrated that the metal components were well supported on the catalyst. When the two catalysts were mixed, the yield of bio-oil increased from 51.00% to 64.51%, the carbon recovery rate raised from 69.53% to 88.18%, the energy recovery rate grew from 63.42% to 80.22%, and the S content is relatively reduced by 83.3%. Also, TG analysis showed that the content of light components in bio-oil increased. Moreover, the hydrocarbons and alcohols were observed to a higher proportion from the GC-MS analysis. This new method still has high catalytic activity after repeated use for five times. This study provides a new idea for preparing higher yield and superior quality bio-oil.
