Hydrophobic Pd nanocatalysts for one-pot and high-yield production of liquid furanic biofuels at low temperatures

Hydrophobic Pd nanocatalysts for one-pot and high-yield production of liquid furanic biofuels at low temperatures

Efficient production of furanic/aromatic hydrocarbons (>95% yields) from biomass derivatives is achieved via a single-step process under mild conditions (25-130 ºC) by using readily available polymethylhydrosiloxane as liquid H-donor over hydrophonic Pd nanoparticles on MOFs.【以聚甲基氢硅氧烷为氢源,在低温条件下 (25-130 ºC),利用疏水纳米钯Pd催化糖类(羰基和羟基化物),一锅高效(> 95% 产量)合成呋喃液体燃料】

 Recently, Dr. Hu Li supervised by Prof. Zhen FANG has developed a single-step catalytic process for direct conversion of various saccharides to produce furanic biofuels such as 2,5-dimethylfuran and 2-methylfuran with high yields (> 95%) at 110-130 ºC. The negatively charged hydride (H-) of readily available polymethylhydrosiloxane (PMHS) acting as green H-donor over hydrophobic Pd nanoparticles did not obstruct upstream reactions (e.g., hydrolysis, isomerization and dehydration) for the in situ formation of furanic aldehydes/alcohols from sugars, and could selectively facilitate the subsequent hydrodeoxygenation of carbonyl and hydroxyl groups other than the furanic ring in one pot, as clarified by deuterium-labeling study. Importantly, the unreduced Pd(II) catalysts also exhibited comparable performance in the selective hydrodeoxygenation reaction. Moreover, the catalytic strategy was extended to various carboxides for quantitative production of corresponding furanic/aromatic hydrocarbons at room temperature that were more pronounced than previously reported results, and the optimal Pd/MIL-53(Al) coated with polydimethylsiloxane (Pd/MIL-53(Al)-P) was highly stable with little deactivation and Pd leaching for at least five consecutive cycles.

高效低温从糖和羰基化物一步直接合成呋喃液体燃料

最近,国际学术期刊Applied Catalysis B: Environmental(影响因子9.4,第一署名单位为南京农业大学,第一作者为博士后李虎,通讯作者为方真教授)及Green Chemistry 【影响因子9.2,第一作者为李虎博士,通讯作者为杨松教授(贵州大学),Saravanamurugan博士(印度)和方真教授】,发表了生物燃料最新研究成果。
该研究团队开发了一个单步催化过程, 以聚甲基氢硅氧烷polymethylhydrosiloxane (PMHS)为氢源,在低温条件下 (25-130 ºC),利用疏水纳米钯(Pd)催化糖类(羰基和羟基化物),单步高效(> 95% 产量)合成呋喃液体燃料。
他们发现PMHS(带负电荷的高分子氢化物),作为绿色氢源,以纳米钯为催化剂,在原位加氢糖类合成呋喃醛/醇时,不会阻碍其上游的反应 (例如, 水解, 异构化和脱水)。通过同位素氘标记研究证明,该反应系统可以一锅法,有选择地促进羰基和羟基化物的加氢脱氧。更重要的是, 未还原的Pd(II)纳米催化剂在选择性加氢脱氧反应中也表现出相当的性能。此外, 当该催化反应系统扩展到利用各种羰基化物时, 可在室温下,定量生产相应的呋喃/芳烃。用聚二甲基硅氧烷涂层的疏水Pd催化剂具有极高的稳定性, 且在至少连续五个周期中几乎没有失活和Pd浸出。

Synthesis of Magnetic Carbonaceous Solid Acid and Base from Jatropha Hulls for the Production of Jatropha Biodiesel

Synthesis of Magnetic Carbonaceous Solid Acid and Base from Jatropha Hulls for the Production of Jatropha Biodiesel

Jatropha seeds were extracted oil for biodiesel production and the hulls were carbonized to load active sites as magnetic carbonaceous solid acid and base catalysts. Crude Jatropha oil was esterified to decrease its acid value to 1.3 from 17.2 mg KOH/g by the solid acid, and subsequently transesterified to biodiesel (96.7% yield) catalyzed by the solid base. After 3 cycles and magnetically separated, the deactivated base was catalyzed the hydrothermal gasification of biodiesel by-product (crude glycerol) with gasification rate of 81% and 82% H2 purity.

    Recently, biomass group synthesized magnetic carbonaceous solid acid (C-SO3H@Fe/JHC) and base (Na2SiO3@Ni/JRC) catalysts by loading active groups on the carbonaceous supporters derived from Jatropha-hull hydrolysate and hydrolysis residue. Characterization of their morphology, magnetic saturation, functional groups and total acid/base contents were performed by various techniques. Additional acidic functional groups that formed with Jatropha-hull hydrolysate contributed to the high acidity of C-SO3H@Fe/JHC catalyst for the pretreatment (esterification) of crude Jatropha oil with high acid values (AV). The AV of esterified Jatropha oil dropped down from 17.2 to 1.3 mg KOH/g, achieving a high biodiesel yield of 96.7% after subsequent transesterification reaction with Na2SiO3@Ni/JRC base that was cycled at least 3 times with little loss of catalysis activity. Both solid acid and base catalysts were easily recovered by magnetic force with average recovery yields of 90.3 wt% and 86.7%, respectively. After washed by ethanol, the catalysts were cycled for 10 times. The AV of esterified oil and biodiesel yield using the recycled catalysts remained below 2.0 mg KOH/g and above 85%, respectively. The existence of catalyst ions and residual methanol contributed to high H2 yield (81.0%) and high purity (81.7%) in the hydrothermal gasification of glycerol by-product using the deactivated solid base.

Catalytic transfer hydrogenation (CTH) is a sustainable and selective way to increase the hydrogen content of unsaturated molecules for producing either biofuels or valuable chemicals. Dr. Hu Li, a postdoctoral student, supervised by Profs. Song Yang (Guizhou university) and Zhen Fang prepared a series of mesoporous and orderly layered nanohybrids for the first time via simple and template-free assembly of zirconium with different xylylenediphosphonates. It was found that m-PhPZr nanoparticles (ca. 20-50 nm) with mesopores centered at 7.9 nm, and high molar ratio of Lewis acid to base sites (1:0.7) exhibited superior performance in CTH of ketones and biomass-derived aldehydes to corresponding alcohols with almost quantitative yields under mild conditions (as low as 82 ºC), especially in CTH of ethyl levulinate to the biofuel additive γ-valerolactone (up to 98% yield). It also showed high activity in one-pot production of biodiesel (with 89% yield) from high acid value oil, and in 5-hydroxymethylfurfural production (with 56% yield) via isomerization and dehydration of glucose. The catalyst is stable with little Zr leaching and deactivation after 5 cycles. Lewis acidic (Zr) and basic (PO3) centers of the heterogeneous catalyst were revealed to play a synergistic role in CTH of carbonyl compounds, e.g., ethyl levulinate to γ-valerolactone. Isotopic labeling experiments further indicated the occurrence of direct hydrogen transfer rather than metal hydride route.

介孔金属-有机膦酸层片材料的制备及其用于转移加氢合成生物燃料

催化转移加氢 (CTH; Catalytic transfer hydrogenation) 是一种可持续、选择性的方法来增加用于生产生物燃料或有价值的化学物质的不饱和分子中氢含量。生物能源组博士后李虎在杨松教授(贵州大学)和方真教授的指导下,通过简单、无模板的组装方法,用锆和不同的苯膦酸,合成了一系列的介孔和有序层状的纳米杂化材料。实验结果表明,m-PhPZr 纳米颗粒 (约 20-50  nm) 具有 7.9 nm介孔中心和高摩尔比的路易斯酸/碱 (1/0.7), 展现出在催化转移加氢酮和醛类生物质平台分子为相应的醇的优越性能,给出几乎定量的产率,反应温度温和(低至 82 º C),特别是在催化乙酰丙酸乙酯生成生物燃料γ-内酯具有高的活性(高达 98%的产率)。该催化剂,可从高酸值油脂中,一步法生产生物柴油 (产率为 89%),通过异构化和脱水葡萄糖生产5-羟甲基糠醛(产率为 56%)。催化剂表现出良好的稳定性,可以重复使用五次。在催化转移加氢羰基化合物(如乙酰丙酸乙酯合成 γ-戊内酯)时,刘易斯酸性 (Zr) 和碱(PO3) 中心发挥协同作用。同位素标记实验进一步预示着发生直接氢转移,而不是金属氢化物路线。
