Stabilization of Global and Chinese rice bowl with disruptive technology

As invited by Prof. Zhen Fang, on April 15^th，Prof. Yi-hang Zhang, Director of the Center for in Vitro Synthetic Biology of Tianjin Institute of Industrial Biotechnology, Chinese Academy of Sciences (CAS), gave an academic lecture at 10 am in C502 conference room of Yixian Building, with the theme of “Agricultural Industrialization+”: Stabilization of global rice bowl with disruptive technology.

Prof. Zhen Fang welcomed the arrival of Prof. Zhang and briefly introduced Prof. Zhang.

Prof. Zhang thanked Prof. Zhen Fang’s invitation to give a lecture on the “two paths and one goal” (straw to starch production and CO₂ production of food for the goal of the strategic needs of national food security) as well as reaching the national carbon goals, guaranteeing people’s health and maintaining rural revitalization to meet the UN sustainable development goals (SDGs). Professor Zhang said that it is necessary to lead the development of a full set of independent and self-improvement new biological refining technologies for producing starch, protein and healthy sugars from straw, the main components of artificial food, and developing straw grain synthesis technologies that are economic viable in 3-5 years. In addition, Professor Zhang also showed that innovative energy-driven material synthesis models will solve the problem of low energy efficiency and slow conversion rate of natural photosynthesis, and it is expected that CO₂ production of artificial food could be industrialized in 2036.

Professor (level 2) of Tianjin Institute of Industrial Biotechnology, CAS. He is director of the National Key Laboratory of Low-carbon Synthetic Engineering Biology, director of the Center for in Vitro Synthetic Biology of Tianjin Institute, doctoral supervisor. He is “One Hundred Program Scholar” (class A) of CAS, one of the world’s most-recognized pioneers in vitro synthetic biology who proposed the design principle of in vitro multi-enzyme molecular machines for the first time. He developed the electricity-hydrogen-sugar (secondary energy) cycle theory that systematically solves the problems of electricity storage, hydrogen production, storage and transportation, and realizes the production of high-quality hydrogen energy at ambient conditions for the first time. He developed a full set of independent self-reliant industrialization technologies for the “new biorefinery plant” for producing artificial food, and led the starch-to-inositol (vitamin B8) project, the world’s first industrial demonstration of in vitro synthetic biotechnology, and pioneered a new method for inositol biomanufacturing.

Non-quantum nanostructures-enabled hot carriers generation for enhancive photoelectrocatalytic oxidation of bio-alcohol in water coupled with hydrogen evolution

Recently, PhD student Mr Pei-dong Wu supervised by Profs. Hu Li and Zhen Fang published research article in Green Chem about photoelectrocatalytic oxidation of bio-alcohol in water coupled with hydrogen evolution.

Photoelectrochemical system is a promising way for biomass valorization but still in its infancy. Herein, a Mo-BVO-TiCoNO-CoFeO_xy photoanode with a nanowire structure was prepared for efficiently converting bio-based benzyl alcohol (BA) to benzoic acid (97.7% yield) for the first time, while coupling H₂ production of 136.8  μmol cm^-2. The nanowire structure enables a significant increase in the exposed active sites on the photoelectrode surface to enhance the BA oxidation capacity, whereas its large aspect ratio increases the visible light absorption and thermal effect (resulting from size effect) increases H₂ production at the counter electrode. DFT calculations and further experiments revealed that Co species of the CoFeO_xy layer functioned as stabilizers of photoelectrode property while Fe species acted as catalytic site providers in the BA oxidation.

The use of photoelectrochemical system for the high value use of biomass-derived alcohols coupled with hydrogen production is a significant contribution to the “two-carbon”. The loading of a “two birds with one stone” CoFeO_xy layer on BVO substrate enabled rapid separation of photoexctied carriers while achieving a 97.7% yield of benzyl alcohol (BA) to benzoic acid (BEN). 使用光电化学（PEC）的方法将生物质衍生醇高值化利用耦合产氢，对于“双碳”目标的实现具有极大的促进意义。我们在钒酸铋基底上负载具有“一石二鸟”作用的CoFeO_xy外层实现光致载流子的快速分离，同时实现对苯甲醇（BA）到苯甲酸（BEN）97.7%的产率。

非量子纳米结构产生热载流子增强光电氧化生物质醇同时耦合产氢的能力

 

最近，博士生吴培栋在李虎教授和方真教授的指导下，在国际学术期刊Green Chemistry (Q1; Impact factor: 11)上发表了一篇关于光电化学氧化生物质醇到苯甲酸的研究性论文。

PEC氧化系统是一种很有前途的方法可以将生物质高值化利用，但仍处于起步阶段。在此基础上，我们制备了具有纳米线结构的Mo-BVO-TiCoNO-CoFeO_xy光阳极，首次将生物质衍生醇-苯甲醇(BA)高效转化为苯甲酸(收率97.7%)，同时偶联H₂产量为136.8  μmol cm^-2。纳米线结构使暴露在光电极表面的活性物显著增加，从而增强BA氧化能力，而其较大的纵横比增加了其可见光吸收，同时产生的热效应(由尺寸效应引起)增加了对电极H₂的产量。DFT计算和对照实验表明，CoFeO_xy层中的Co物种是光电极性能的稳定剂，Fe物种在BA氧化的过程中提供了催化位点。

Microwave-assisted one-step production of biodiesel from waste cooking oil by magnetic bifunctional SrO–ZnO/MOF catalyst

Recently, master student Mr. Jian Yang supervised by Prof. Zhen Fang published a research article in Journal of Cleaner Production about synthesizing bifunctional SrO–ZnO/MOF catalyst for biodiesel production from waste cooking oil.

Magnetic bifunctional SrO–ZnO/MOF catalyst supported on metal-organic framework (MOF) was synthesized for one-step biodiesel production from high acid value oils. The catalyst presented both basicity (2.84 mmol/g) and acidity (0.02 mmol/g) due to active components of Sr₃Fe₂O₆ and ZnO. MOF support increased catalyst specific surface by 3.7 times and provided Fe₃O₄ component for magnetic separation. The highest soybean biodiesel yield of 99.5% was obtained at 80 ℃ with 3 catalyst cycles. Microwave heating significantly reduced reaction time from 20 min to 5 min at 99.0% biodiesel yield and 80 ℃. The catalyst was highly active and resistant to free fatty acids with biodiesel yield of 90.0% from waste cooking oil (AV of 3.3 mg KOH/g) at longer reaction time of 30 min. SrO–ZnO/MOF has potential application in biodiesel industry.

Related results were accepted in Journal of Cleaner Production.

最近，硕士生杨剑在方真教授的指导下，在国际学术期刊Journal of Cleaner Production （Q1, IF 11.072）发表一篇关于使用双功能磁性SrO–ZnO/MOF催化剂从废弃食用油中制备生物柴油的研究性论文。

合成了由金属有机骨架（MOF）负载的磁性双功能SrO–ZnO/MOF催化剂，用于高酸值油一步制备生物柴油。Sr₃Fe₂O₆和ZnO为催化剂提供碱度（2.84mmol/g）和酸度（0.02mmol/g）。MOF载体将催化剂比表面积提高了3.7倍，形成的Fe₃O₄赋予催化剂磁性。催化豆油制备生物柴油的产率在80 ℃下达到99.5%，通过简单的磁性分离催化剂可循环使用3次。微波加热显著缩短了反应时间，在相同的生物柴油产率（99.0%）下，传统油浴加热需要20 min，而微波加热将反应时间缩短3倍，仅用了5 min。该催化剂具有高度活性，并且对游离脂肪酸具有抗性，在80 ℃下反应30分钟，催化酸值为3.3 mg KOH/g的废弃食用油的生物柴油产率达到90.0%。SrO–ZnO/MOF催化剂在生物柴油工业中具有潜在应用。
