中文摘要：

生物质是唯一能替代化石资源转化得到液体燃料及化学品的可再生资源,近年来,催化转化生物质制备各种平台化合物的研究受到了人们越来越广泛的关注。和乙酰丙酸（LA）一样,γ-戊内酯（GVL）也被认为是一种具有广泛应用潜能的新型生物质基平台化合物。目前,人们已经开发出多种催化剂和反应体系用于催化生物质基LA选择性还原制备GVL。根据氢源的不同可将LA制备GVL的途径概括为4种：分别以分子H2、甲酸（FA）、合成气和醇类作为氢源的途径。本文着重从氢源的差异来归纳和总结生物质基LA选择性还原制备GVL的途径及其研究进展,以期为寻找一种高效、经济、环保的GVL合成途径提供一些思路和参考。

英文摘要：

Biomass is the only renewable resources on the earth that can be converted to liquid fuels and chemicals to replace fossil resources. Recently, the catalytic conversion of biomass to platform molecules has attracted more and more attentions from the researchers worldwide. γ-Valerolactone （GVL） is regarded as a platform molecule that has extensive application potential, similar to levulinic acid （LA）. Up to now, various of catalysts and reaction systems were developed and applied to the selective reduction of biomass-derived LA to GVL, and the hydrogenation of LA can be driven by various hydrogen sources, including molecule H2, formic acid （FA）, syngas and alcohols. In this review, the catalytic hydrogenation routes and recent research progress for the reduction of LA are systematically summarized in view of the diversity of hydrogen sources. The future research trends of the selective reduction of LA to GVL are suggested.
