卡宾及其配合物案例教学的设计思想是将基础理论与前沿研究相结合来进行课堂教学。在对文献所报道的研究成果用基础理论进行抽丝剥茧地分析和讨论过程中，帮助学生夯实基础，真正做到固本强基的同时培养学生的创新意识与创新能力。

将三聚氰胺、RuCl₃及炭黑以一定的比例分散于乙醇中，采用旋转蒸干及高温热处理合成了一种氮掺杂碳(NC)负载Ru的Ru/NC催化剂。采用硼氢化钠液相化学还原法合成了不同Pt、Ru负载量的PtRu/NC催化剂，并用于电催化甲醇氧化反应(MOR)及电催化分解水析氢反应(HER)。结果表明，合成的催化剂中Pt₁Ru/NC(Pt、Ru的实际负载量分别为1.14%、0.54%)表现出最优的MOR性能，质量活性达4.96 A·mg_PtRu^-1，且经10 000 s稳定性测试后质量活性保持在测试前的91.1%。同时，当电流密度为100mA·cm^-2时，Pt₁Ru/NC在HER中表现出最低的过电位(103 mV)和最小的Tafel斜率(15.29 mV·dec^-1)。通过X射线衍射(XRD)、X射线光电子能谱(XPS)、透射电子显微镜(TEM)、扫描透射电子显微镜(STEM)、电感耦合等离子体发射光谱(ICP-OES)、STEM-能谱(STEM-EDS)技术表征了PtRu/NC双金属催化剂，其具有优异催化性能的原因如下：(1) PtRu双金属纳米颗粒高度分散于NC上；(2) Pt以纳米团簇或单原子形式负载于Ru上，后负载于NC，形成了Pt-Ru相分离结构；(3) Pt、Ru与N之间存在协同效应。

A flower-like BiOBr photocatalyst (CS/BiOBr) was prepared by using the carbon material derived from corn straw (CS) as the carrier. The prepared composites were characterized by X - ray diffraction (XRD), Fourier transform infrared (FIIR) spectra, scanning electron microscope (SEM), X - ray photoelectron spectra (XPS), and UV-Vis diffuse reflectance spectra (UV-Vis DRS). The SEM analyses indicate that the introduction of CS promotes the formation of a unique flower-like structure in BiOBr, which not only optimizes the efficiency of light capture but also increases the specific surface area of BiOBr. The bandgap of the composite was narrower compared with the pure BiOBr. The CS/BiOBr composites exhibited higher photocatalytic activity than pure CS and BiOBr under visible light irradiation, and a higher first-order reaction rate constant (k) of 0.043 7 min^-1 than BiOBr (0.014 6 min^-1), and exhibited excellent stability and reusability during the cyclic run. The enhanced photocatalytic activity is attributed to the efficient separation of photoinduced electrons and holes. Superoxide radicals and holes were the major active species.
