6月2日上午9:00，材料科学与工程学院在千佛山校区主楼二楼会议室举办“求材”学术论坛。此次论坛由山东大学研究生院、材料液固结构演变与加工教育部重点实验室及材料科学与工程学院共同主办，材料学院研究生会承办。应山东大学慈立杰教授邀请，颜清宇教授、范红金教授和徐梽川教授到访山东大学，并分别作了题为“Multi-functional Few Layered Black Phosphorus Composite”、“High Rate Performance of Metal-ion Battery Electrodes”和“Oxygen Electrocatalysis on Transition Metal Spinel Oxides”的报告。材料学院慈立杰老师、冯金奎老师、司鹏超老师等出席此次论坛，材料学院各年级研究生参加了此次论坛。

颜清宇首先介绍了黑磷作为一种电池负极材料的优势，相比于白磷和红磷，黑磷的导电性最好。然后介绍了两种制备方法：液相剥离法和高压反应釜法，液相剥离制备得到的黑磷具有热电性能好、储能好和空气稳定性好等优点，但容量较小成为制约其发展的关键点，高压反应釜制备的样品表面氧化物较多，应用也受到限制。最后，他们课题组将LiP加入电池材料中，提高了导电性并降低了导热率，取得了显著的成果。

范金红以如何提高金属离子电池电极的高倍率性能为主题，详细介绍了通过纳米尺寸减小、增加扫描速率或放电电流、晶体结构（TiO₂，WO₃·2H₂O）等方法提高金属离子电池电极的高倍率性能，并最终得到两个结论：（1）二维材料设计的高非本征赝电容效应具有高利率和更好稳定性的优点；（2）通过表面钝化使Sn基电极循环稳定性变的更容易（loose TiO₂ shell，SiO_x/rGO，vertical graphene）。

徐梽川通过几个例子详细介绍了过渡金属尖晶石氧化物的氧电催化性能研究，他说道，材料本质决定材料的性能，反向轨道电子数决定材料的活性。他还说道，价态变化能力和取代阳离子的几何占有性决定了尖晶石铁氧体的赝电容性。最后发现在八面体位点填充阳离子是过渡金属氧化物尖晶石的ORR＆OER活性，并发现一种高活性的OER催化剂材料。

三位教授为我院师生奉献了一场精彩的报告，报告结束后，与会师生和报告人热烈讨论，学术氛围十分浓厚，会场不时响起热烈掌声，大家都感到受益匪浅。
