高校思想政治理论课承担着对大学生进行马克思主义系统化教学的任务,是对学生进行思想政治教育的主渠道。但是,高校思政课堂出勤率低的现象十分普遍,长此以往可能会对学生、教师及教学产生不良影响。造成此现象的原因包含多个方面:学生自身缺乏自主成长的心理和自我管理的能力、对思政课认识不足或群体文化的影响等,课堂因素包括内容枯燥、缺乏互动性等,以及外界因素,如娱乐方式的增多、学生兼职或考研的影响等,需要高校和学生共同改进,如激发学生兴趣、改进教学方式、增加学风建设等等,努力提高高校思政课堂的出勤率。

人工半导体光催化CO_(2)转化被广泛认为是模拟自然碳循环的最有前途的策略之一。其中,Bi_(2)MoO_(6)具有光催化CO_(2)转化的潜力。然而,由于其光生电荷载体的快速复合,其催化性能仍然不足。因此,改善Bi_(2)MoO_(6)的催化效率是一个紧迫的问题。在这项研究中,我们通过水热法合成了Bi_(2)MoO_(6)纳米片,并在其表面同时生长了CeO_(2)纳米颗粒,形成了Ce^(3+)/Ce^(4+)离子桥接修饰的S型异质结。时间分辨光致发光光谱和光电化学测试揭示了这种异质结的增强电荷分离效应。此外,原位X射线光电子能谱分析和理论计算进一步证实,光生电子转移路径遵循S型机制,从氧化型半导体Bi_(2)MoO_(6)的导带转移到还原型半导体CeO_(2)的价带。实验结果表明,CeO_(2)/Bi_(2)MoO_(6)、Bi_(2)MoO_(6)和CeO_(2)的光催化CO_(2)还原为CO的效率分别为65.3、14.8和1.2μmol·g^(-1)·h^(-1)。与纯Bi_(2)MoO_(6)相比,CeO_(2)/Bi_(2)MoO_(6)复合催化剂将CO_(2)光催化还原为CO的催化效率提高了3.12倍。这项工作为设计和构建新型S型异质结光催化剂提供了独特的见解。
