This work studied a concurrent UV photocatalysis and alkaline H₂O₂ pretreatment (UHP) to enhance the subsequent enzymatic hydrolysis of sisal waste in comparison with alkaline H₂O₂ pretreatment (AHP). An optimal condition was identified for UHP at H₂O₂ charge 0.1 g/g dried sisal waste, pH 10.0, and UV radiation for 6 h. Under this condition, UHP led to a delignification rate of 76.6%, a conversion to reducing sugar at 71.2%, and a conversion to glucose at 91.6%, respectively. XRD, FT-IR and SEM analysis showed an increase in crystalline degree and significant changes in the structure of sisal during UHP. The current study implicates that UHP is more efficient than AHP in pretreating sisal waste, with reduced H₂O₂ charge, shortened pretreatment time, and enhanced enzymatic digestibility.

这项工作研究了同时进行的UV光催化和碱性H ₂ O ₂预处理（UHP），与碱性H ₂ O ₂预处理（AHP）相比，可以增强随后的剑麻废料的酶促水解。确定了H ₂ O _2下UHP的最佳条件充入0.1 g / g的剑麻废液，pH 10.0和UV辐射6小时。在这种条件下，UHP的去木质素率达到76.6％，还原糖转化率为71.2％，葡萄糖转化率为91.6％。XRD，FT-IR和SEM分析表明，UHP过程中剑麻的结晶度增加，剑麻的结构发生了显着变化。当前的研究表明，在预处理剑麻废物方面，UHP比AHP更有效，减少了H ₂ O _2的加入，缩短了预处理时间，并增强了酶消化率。
