Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Carbon dots (CDs) have emerged as promising modifiers for boosting the photocatalytic H2O2 production, yet their precise role remains to be quantitatively elucidated. Herein, S, N‐codoped lignin‐derived carbon dots (SN‐LCDs) and lignin‐derived carbon dots (LCDs) were synthesized and employed to modify TiO2.

, 2015 本发明提供了一种制备木质素与丙烯腈共聚物的方法，首先将不饱和酰氯与木质素发生酯化反应，利用不饱和酰氯改性木质素，使木质素分子中的羟基转变为酯基，同时引入不饱和碳碳双键，得到酯化木质素；然后将该酯化木质素与丙烯腈单体进行均相溶液自由基共聚合反应，得到酯化木质素与丙烯腈的共聚物。该方法有效提高了木质素与丙烯腈的共聚反应效率，实现了木质素的高效利用。利用溶液湿法纺丝工艺，以该方法制得的木质素与丙烯腈的共聚物作为纺丝液制备纤维，再经预氧化和炭化制备碳纤维时，不仅能够阻止木质素在湿法纺丝凝固成型过程中流失 ...
