拓展生物质产业链，开发附加值高的精细化工产品，实现生物质资源的高效利用是当前政府与学术界非常重视的任务和目标。将生物质转化成可被化学工业利用的起始原料，不仅可以缓解当前能源和资源现状，而且符合低碳经济的理念。本项目拟构建对糠醛选择氢解具有较好催化性能的小尺寸Co基双金属催化剂，以调控金属-载体间相互作用为手段，以提高1,2和1,5-戊二醇活性和选择性为目标，通过系统而深入的研究，达到定向催化转化糠醛的目的。研究催化剂的纳米粒子结构、表面性质、金属与载体相互作用等因素对糠醛及其衍生物选择氢解反应的活化作用。在此基础上，结合原位高压红外、量热及理论计算等方法研究糠醛选择氢解过程中反应物的吸附与反应行为，阐明处于金属载体强相互作用状态的Co基双金属催化剂上糠醛选择氢解反应机理，为实现生物质原料高效、高选择性转化奠定科学基础。

Expanding biomass industrial chain and developing value-added chemicals to realize its high efficient utilization is currently one of the primary goals of the government, the industry and the academia. Conversion of biomass into materials that can be directly utilized in chemical industry can effectively alleviate the energy and resources crisis which is in consistent with the concept of low carbon economy. This proposal is aiming at the design and development of highly efficient Co-based bimetallic catalysts for the direct and selective hydrogenolysis of furfural to 1,2 and 1,5-pentanediols. The systematic study involves investigating the influence of catalyst structure, surface properties, and the metal-support interactions on the selective hydrogenolysis of furfural and its derivatives. Through a series of well-conceived experiments such as in-situ infrared, micro-calorimetry and so on, and by theoretical calculations, we will first study the adsorption and reaction behaviours of furfural over the bimetallic catalysts. And then explore the reaction mechanism in detail to lay down a reliable scientific foundation in the efficient and selective conversion of furfural to pentane diols over Co-bimetallic catalysts with strong metal–support interactions.
