Photocatalytic aerobic oxidation reactions are largely governed by the efficiency of charge separation and subsequent reactive oxygen species(ROS) generation. Herein, we report a polarization engineering strategy to promote the charge separation and ROS generation efficiency by substituting the benzene unit with furan/thiophene in porous organic polymers(POPs). Benefiting from the extent of local polarization, the thiophene-containing POP(JNU-218) exhibits the best photocatalytic performance in aerobic oxidation reactions, with a yield much higher than those for the furan-containing POP(JNU-217) and the benzenecontaining POP(JNU-216). Experimental studies and theoretical calculations reveal that the increase of local polarization can indeed reduce the exciton binding energy, and therefore facilitate the separation of electron-hole pairs. This work demonstrates a viable strategy to tune charge separation and ROS generation efficiency by modulating the dipole moments of the building blocks in porous polymeric organic semiconductors.

钴多以伴生元素赋存于硫化铜镍矿床中,在冶炼过程中主要富集于转炉渣中。从转炉渣中回收钴,能够缓解我国钴的供需矛盾,具有显著的经济和社会效益。本文针对镍转炉的物相组成进行了系统分析,并在此基础上通过热力学分析及实验研究,实现了非熔融状态下钴、镍等氧化物的还原及富集。考察了焙烧温度、还原时间、无烟煤及氯化钙用量对各金属回收率及磁选精矿中金属含量的影响。结果表明:优化工艺条件为还原温度1050~1150℃、无烟煤用量(质量分数)10%、氯化钙用量13%、还原时间为1.5 h。在此条件下,铁、钴、镍、铜的回收率分别为51.85%、93.81%、98.32%、76.47%,在磁选精矿中的含量(质量分数)分别为45.08%、8.14%、18.70%、2.06%。
