Design of heterogeneous catalyst to achieve efficient conversion of biomass to high added-value chemicals is still very attractive. Herein, taking industrially important selective hydrogenation of furfural to furfuryl alcohol as an example, the designed amorphized HA zeolite encapsulation of platinum clusters (denoted as Pt@HA) exhibited excellent catalytic selectivity at totally conversion of the reactant furfural, along with good reusability and poison resistance ability. The selected amorphized HA zeolite with very small pore size constrained the reactant furfural to be reacted through hydrogen spillover process at zeolite surface, instead of to be adsorbed and activated onto Pt surface. Resulting from the stronger interaction between nucleophilic oxygen atom of aldehyde group and acid site at HA zeolite surface than that of furan ring group, furfural preferred to adsorb onto Pt@HA surface with the end of aldehyde group rather than the end of furan ring group, thus facilitating the spilled H atom to react with aldehyde group to give desired furfuryl alcohol product exclusively.

设计多相催化剂以实现生物质高效转化为高附加值化学品仍然非常有吸引力。本文以工业上重要的糠醛选择性加氢制糠醇为例，设计的铂簇包覆非晶化HA沸石（表示为Pt@HA）在反应物糠醛完全转化时表现出优异的催化选择性，同时具有良好的可重复使用性和毒性。抵抗能力。所选的非晶化HA沸石具有非常小的孔径，限制了反应物糠醛通过沸石表面的氢溢出过程进行反应，而不是吸附并活化到Pt表面上。由于醛基亲核氧原子与HA沸石表面酸性位点的相互作用强于呋喃环基团，糠醛优先吸附在醛基末端而不是呋喃环基末端的Pt@HA表面上，从而促进溢出的H原子与醛基反应专门得到所需的糠醇产物。
