Abstract

This study presents an efficient strategy for converting high-boiling solvent (HBS) pretreated cellulose into lactic acid (LA) over a Cr-Sn-Beta bimetallic catalyst synthesized by flash Joule heating (FJH). Ethylene glycol-based HBS pretreatment effectively enriched cellulose content in straw, while the FJH method enabled rapid and uniform metal incorporation. The resulting Cr-Sn-Beta catalyst exhibited a maximum LA yield of 33.54% with a carbon balance of 90.08%, showing high selectivity and catalytic efficiency. The synergistic function of Cr and Sn acid sites was also evaluated. This work provides a promising route for biomass valorization and catalyst design via combined pretreatment and advanced synthesis techniques.

利用闪蒸焦耳加热制备的cr - sn - β双金属催化剂将纤维素转化为乳酸

本研究提出了一种利用闪速焦耳加热（FJH）合成Cr-Sn-Beta双金属催化剂将高沸点溶剂（HBS）预处理纤维素转化为乳酸（LA）的有效策略。乙烯基HBS预处理能有效地提高秸秆中纤维素的含量，而FJH法能快速均匀地加入金属。结果表明，Cr-Sn-Beta催化剂的LA产率最高为33.54%，碳平衡为90.08%，具有较高的选择性和催化效率。并对Cr和Sn酸位点的协同作用进行了评价。本研究为预处理与先进合成技术相结合的生物质增值和催化剂设计提供了一条有前景的途径。

期刊介绍： Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
