采用气固法制备了磷化钼-碳纳米花(MoP-CFs)，通过简单的超声自组装将C₆₀修饰在MoP-CFs表面，形成范德瓦耳斯异质结。研究其电催化析氢性能发现，C₆₀的修饰能够有效降低电催化析氢过电位。其中，10% C₆₀-MoP-CFs样品(10%为C₆₀的质量分数)表现出最佳催化活性，在酸性和碱性条件下达到10 mA·cm^-2的电流密度时，所需要的过电位分别为158和157 mV，并且具有至少20 h的电催化稳定性。C₆₀与MoP-CFs之间强电子耦合作用促进电子由C₆₀迁移到MoP-CFs表面，有助于减小电荷传输阻力，加快电催化析氢界面反应动力学过程。

采用原位聚合法制备了氯氧化铋(BiOCl)与聚苯胺(PANI)复合的Ⅱ型异质结光催化剂BiOCl/PANI，并采用X射线衍射(XRD)、傅里叶变换红外光谱(FTIR)、透射电子显微镜(TEM)、X射线光电子能谱(XPS)、紫外可见漫反射光谱(UV-Vis DRS)和N2吸附-脱附测试等多种技术手段对其进行了表征，考察了BiOCl/PANI在模拟可见光下对罗丹明B (RhB)的光催化降解性能。实验结果表明：BiOCl/PANI催化剂比PANI和BiOCl具有更高的光催化活性，在RhB质量浓度为50 mg·L^-1、PANI与BiOCl的物质的量之比为0.02∶1、50 mg·L^-1的催化剂条件下，所制备的BiOCl/PANI光催化150 min后，RhB降解率为98.8%，速率常数为0.031 min^-1；经过4次循环实验后，RhB降解率从98.8%降低至98.4%，表现出良好的稳定性和可重复利用性。光催化剂BiOCl/PANI实现了电子和空穴对的快速分离，降低了二者在催化剂内部的复合速率，提高了光催化性能。

仪器分析实验“分子荧光法测定罗丹明B的含量”存在实验过于简单、未考虑实际情况等问题。因此，本改进实验在三维荧光扫描模式下获取样本数据，不进行复杂预处理，而是运用化学计量学算法解析出目标分析物的纯信号，进而实现了染色辣椒中罗丹明6G和123的同时测定。本改进实验提高了学生全面考虑问题和创新解决问题的能力。

通过微波加热方式，快速合成了3个葡萄糖修饰的双席夫碱。通过比浊度分析、HRP/Amplex Red实验、DCFH-DA荧光探针实验、NBT分析法以及MTT实验检测它们抑制金属离子诱导的Aβ聚集、减少活性氧(ROS)生成及抑制Aβ聚集产生的细胞毒性。发现葡萄糖修饰的双席夫碱都能有效抑制金属离子(Zn²⁺、Cu²⁺)诱导的Aβ_1~40的聚集，降低Cu²⁺-Aβ加合物催化产生ROS水平、提高Cu²⁺-Aβ作用的细胞内超氧化物歧化酶的活力，有效抑制Zn²⁺或Cu²⁺诱导Aβ聚集而产生的神经细胞毒性并大幅提高细胞存活率。作为对比，我们也检测了相同条件下的氯碘羟喹(cliquinol, CQ)和没有葡萄糖修饰的同类双席夫碱的活性，发现葡萄糖修饰的双席夫碱各方面活性均好于CQ；葡萄糖修饰的双席夫碱自身毒性小、抗氧化和提高Aβ与金属离子共同处理的细胞的存活率方面均优于未葡萄糖官能化的同类双席夫碱。

A simple two-step hydrothermal method synthesized four different CdS/Fe₃O₄ photocatalysts with varying ratios of mass of CdS to Fe₃O₄. The composition and morphology of the prepared samples were investigated using X-ray diffraction (XRD), Raman spectrum, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Solid UV reflectance spectra testing found that CdS/Fe₃O₄ nanocomposites had good light absorption throughout the spectral range, promoting their photocatalytic properties. Under visible light irradiation, CdS/Fe₃O₄ (2:5) with a mass ratio of 2:5 exhibited excellent photocatalytic performance, with a degradation rate of 98.8% for rhodamine B. Furthermore, after five cycles of photocatalytic degradation reaction, the rhodamine B degradation rate remained at 96.2%, indicating that the photocatalysts have good photocatalytic stability.

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.
