硕博答辩
2024年5月20日下午，南京农业大学生物能源组2020级博士研究生吴培栋和硕士研究生郭文娟（女）、徐功迅（导师方真教授）、谢葛亮（导师徐禄江副教授）毕业答辩会在南京农业大学浦口校区育贤楼C302举行。南京农业大学的郑恩来教授担任答辩评审委员会主席，南京林业大学的陈登宇教授，江苏大学的王爽教授，南京农业大学的李坤权教授、丁为民教授和何春霞教授共六位专家担任答辩评审委员。
答辩会上，吴培栋、郭文娟、徐功迅和谢葛亮四位同学依次对其在校期间的学术论文进行汇报，同时答辩委员会主席和各位评委提出了相关问题。根据四位同学的问题回答以及学位论文的外审意见，评委会经过评审决议，一致认为吴培栋、郭文娟、徐功迅和谢葛亮四位同学顺利完成了毕业所需要的研究和学习要求。
吴培栋同学在毕业论文《可见光响应光阳极的构筑及其光电催化合成木质素基富氧化合物的研究》中以BiVO4、α-Fe2O3和TiO2光电极为出发点，通过掺杂和引入过渡金属基（Mn、Fe、Co和Ni）助催化剂等策略去改善上述问题，构筑了具有潜在应用前景的复合光电极。同时选取木质素衍生醇、酮、β-O-4二聚体和β-1二聚体作为底物，研究光电极界面活性位点与底物的作用机制，阐明C-O成键、C-C断键的机理以促进上述底物高效、专一化升级为芳香族羧酸。郭文娟同学在毕业论文《基于实验与机器学习的生物质催化热解制备酚类物质特性研究》中对生物质催化热解定向制备酚类物质的工艺方法和产率影响因素进行了研究，分析了氮掺杂生物炭催化剂热解过程中产酚的作用机理，并构建了基于生物质原料特性、热解条件和催化剂孔隙特性的苯酚产率预测模型。徐功迅同学在毕业论文《赤泥负载Ni-Cu双金属材料用于生物质水热制氢》通过改性与探究寻找到了一种成本低廉且高效的赤泥基催化剂。对比了不同金属负载量和金属促进剂对赤泥基催化剂性能的影响，确定了30Ni-2.5Cu/RM为最优催化剂。运用了BET、XRD、TPR、XRF等多种技术手段进行深入分析，揭示催化剂的可能催化机理。同时，还对实验温度、时间、催化剂用量及棉秆用量这四个关键参数进行了系统优化，以确定最佳的实验条件。在找到最优条件后，进一步将其应用于多种农业废弃物及模型化合物的气化实验中。谢葛亮同学在毕业论文《基于含氧官能团定向热转化的废弃芳香资源高值利用研究》中研究了芳香族含氧聚合物的下游高值化利用，通过木质素与POM的催化共热解成功合成了富含芳香族烃的生物油，此外通过一锅法氨化与气相加氢脱氧(HDO)两步实现了木质素基香草醛到羟基苯甲腈的绿色制备，还通过PET与尿素的共热解制备了对苯二甲腈。
吴培栋同学以第一作者身份共发表学术论文3篇，郭文娟同学以第一作者身份共发表学术论文1篇，徐功迅同学以第一作者身份共发表学术论文2篇，谢葛亮同学以第一作者身份共发表学术论文3篇，四位同学均获得了2024年南京农业大学优秀毕业生称号。
经评委会无记名投票表决，一致同意吴培栋同学通过博士学位论文答辩，建议授予工学博士学位；郭文娟同学通过硕士学位论文答辩，建议授予郭文娟电子信息专业硕士学位；徐功迅同学通过硕士学位论文答辩，建议授予徐功迅工学硕士学位；谢葛亮同学通过硕士学位论文答辩，建议授予谢葛亮工学硕士学位。
祝贺四位同学！
