A novel biomass-derived mesoporous bifunctional hybrid (FDCA-Hf) prepared by facile assembly of 2,5-furandicarboxylic acid (FDCA) with hafnium (Hf) was highly stable and active for the production of biofuels and valuable chemicals from bio-based compounds such as ketones, aldehydes and acidic oils via acid-base cooperative catalysis

Recently, Dr. Hu Li supervised by Prof. Zhen  Fang  designed and prepared a new porous and acid-base bifunctional hybrid (FDCA-Hf)  by simple assembly of biomass-derived 2,5-furandicarboxylic acid (FDCA) with hafnium (Hf) under template-free conditions. The resulting FDCA-Hf hybrid with mesopores centered at 6.9 nm, moderate surface area (365.8 m²/g) and acid-base couple sites (density: 0.51 vs 0.97 mmol/g, acid/base molar ratio: 0.53), could selectively catalyze the Meerwein-Ponndorf-Verley reduction of carbonyl compounds under mild reaction conditions (as low as 90 ºC in a short time of 1 h), especially of ethyl levulinate to γ-valerolactone, in quantitative yields (95-100%) and relatively higher reaction rate (e.g., turnover frequency: 2.28 h^-1) compared to other catalysts. Moreover, the efficient simultaneous (trans)esterification of Jatropha oils with high acidic values to biodiesel (up to 98% yield) could also be achieved over FDCA-Hf with robust acid-base catalytic sites. The FDCA-Hf hybrid was highly stable due to the presence of robust metal-organic framework and could be resued with no decline in activity. Further studies demonstrated that the synergistic role of Lewis acid-base couple species (Hf⁴⁺–O^2–) and Brønsted acidic species (-OH) of FDCA-Hf contributed greatly to its pronounced catalytic activity.

Inclusion of Zn into Metallic Ni Enables Selective and Effective Synthesis of 2,5-Dimethylfuran

Recently, Dr. X. Kong supervised by Profs. Y Zhu (Chinese Academy of Sciences) and Zhen Fang developed  a highly selective Ni-based alloy catalyst for furanic fuel production from 5-hydroxymethylfurfuran. The NiZn alloy catalyst was formed through Zn inclusion to Ni by controllable reduction of the NiZnAl hydrotalcite-derived NiO–ZnO–Al₂O₃ mixed oxide. The combination of temperature-programmed reduction (TPR), in situ X-ray diffraction (XRD), CO-adsorbed infrared spectroscopy (CO-IR), and X-ray photoelectron spectroscopy (XPS) revealed that the surface of the NiZn catalyst was composed of β₁-NiZn while the bulk was composed of α-NiZn. Moreover, the surface Ni atoms were geometrically isolated by Zn atoms and modulated to be electron-rich. Finally, the rate of C═O/C—O hydrogenolysis over C═C/C-C hydrogenation for NiZn alloy catalyst was approximately three times higher than that of monometallic Ni catalyst. A 93.6% yield of DMF was obtained over NiZn alloy catalyst. The greatly improved DMF yield was thus attributed to the electron modification and isolation of Ni atoms due to the formation of NiZn alloy.

High yield of DMF (93.6%) was obtained from hydrogenolysis of HMF, which is an important process for sustainable fuel production from biomass.【通过调变金属Ni的电子状态和结构状态，实现了Ni基催化剂高选择性催化5-羟甲基糠醛加氢制呋喃燃料的过程】

高选择性Ni基催化剂催化5-羟甲基糠醛制呋喃液体燃料

最近，国际学术期刊ACS Sustainable Chemistry & Engineering（影响因子5.9，第一署名单位为南京农业大学，第一作者为孔晓，通讯作者为中科院山西煤化所朱玉雷研究员和方真教授），发表了生物能源组催化转化生物质平台分子制生物液体燃料最新研究成果。阐明了NiZn合金化对Ni加氢催化性能的调变。
孔晓博士通过在Ni催化剂上引入金属Zn，形成了NiZn合金催化剂。该催化剂表面由β1-NiZn组成，体相为α-NiZn。合金化过程使得催化剂表面得到调变，金属Zn向金属Ni转移电子，使Ni电子状态发生变化；同时Zn很好的稀释Ni原子，进而减弱呋喃环在Ni上的吸附，最后催化剂表现出较高的5-羟甲基糠醛选择性加氢选择性。

孔晓博士还在斯普林格出版社出版的专著《Production of Biofuels and Chemicals with Bifunctional Catalysts》上应邀撰写书的一章节，详细介绍了非均相催化剂的表征方法和基本原理，以及用固体酸、金属和金属酸双功能催化剂促进纤维素转化。

Production of Liquefied Oil Palm Empty Fruit Bunch Based Polyols via Microwave Heating

Recently, Mr. UA Amran (a PhD student from Universiti Kebangsaan Malaysia, Malaysia) supervised by Profs. S Zakaria and Zhen Fang produced polyols from oil palm wastes using microwave.

Optimization of microwave-assisted liquefaction of oil palm empty fruit bunch fiber (EFB) and cellulose (EFBC) in ethylene glycol (EG) was carried out to produce polyols. The liquefaction residues and hydroxyl numbers of the resultant polyols from respective sources were studied and compared. EFB produced a minimum residue of 3.22% at the optimal parameters of 160 °C and 15 min. Meanwhile, optimum liquefaction of EFBC produced 1.03% residue at 175 °C and 40 min. The maximum hydroxyl numbers of both EFB (749.22 mg KOH/g) and EFBC (639.91 mg KOH/g) polyols were obtained at optimum conditions. FTIR analysis revealed the degradation mechanism of cellulose and lignin in EFB at different temperatures. Lignin was found to be liquefied easily at lower temperatures (130 and 145 °C). However, most of the cellulose began to be liquefied at the optimum temperature (160 °C) and severely degraded at higher temperatures (175 and 190 °C).

Catalytic processes in multiple steps are typically required in the selective conversion of biomass derivatives into value-added chemicals and biofuels. Much effort has been made in the past decades toward the integration of different types of catalytic transformations with a bifunctional catalyst to improve reaction efficiency, enhance product selectivity, and promote specific reaction pathways. This book provides state-of-the-art reviews, current research, prospects, and challenges of production of platform chemicals (e.g., hexose, 5-hydroxymethylfurfural, 2,5-furandicarboxylic acid, furfural, and levulinic acid) and liquid biofuels (e.g.,biodiesel, 2,5-dimethylfuran, 2-methylfuran, and γ-valerolactone) from sustainable biomass resources with cooperative catalytic processes that include heterogeneous bifunctional chemocatalysis (acid-base, Bronsted-Lewis acid, and metal-acid) and combined bio-/chemo-catalytic routes. Fundamentals of bifunctional catalysis and catalysts, characterization reaction mechanism/pathways, methods for heterogeneous catalysts, the impact of catalyst design on the reactivity, and catalytic process integration are introduced. The application of biomass-derived compounds for the synthesis of commodity chemicals and liquid transportation fuels via various catalytic routes is also covered.

This book is the eighth book of the series entitled “Biofuels and Biorefineries,” and it contains 12 chapters contributed by leading experts in the field.

The text should be of interest to students, researchers, academicians, and industrialists who are working in the areas of catalysis, catalyst design, renewable energy, environmental and chemical sciences, engineering, resource development, biomass processing, sustainability, materials, biofuels, and chemical industries.
