The high-value-added chemicals hydroxyacetone (HA) and 1-hydroxy-2-butanone (HB) were produced from agricultural waste over a Ni Sn -SnO catalyst. The Sn-Ni intermetallic compound and SnO acted as the active sites for HA and HB production by selectively cleaving the target C-C and C-O bonds. Approximately 70 % of the total HA and HB yield was obtained by selective hydrogenolysis of cellulose. This strategy expands the application of cellulose towards renewable production of high-value C and C keto-alcohols from cellulosic biomass.
通过镍锡-氧化锡催化剂，利用农业废弃物制备了高附加值化学品羟基丙酮（HA）和1-羟基-2-丁酮（HB）。锡镍金属间化合物和氧化锡通过选择性断裂目标碳-碳键和碳-氧键，作为生成HA和HB的活性位点。纤维素的选择性氢解获得了约70%的HA和HB总产量。该策略拓展了纤维素在从纤维素生物质可再生生产高价值碳和碳酮醇方面的应用。
