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。

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.

我们以宽带隙聚合物聚(3-己基噻吩) (P3HT)为给体，窄带隙聚合物聚{2, 2'-((2Z, 2'Z)-((12, 13-双(2-癸基十四烷基)-6-(2-乙基己基)-4, 8-二甲基-6, 8, 12, 13-四氢-4氢-苯并[1, 2, 3]三唑并噻吩[2'', 3'': 4', 5']并吡咯[2', 3': 4, 5]并吡咯[3, 2-g]并噻吩[2', 3': 4, 5]并吡咯[3, 2-b]并[4, 5-e]吲哚-2, 10-二基)双(甲烷亚甲基))双(5, 5’-3-氧-2, 3-二氢-1氢-2, 1-二亚基茚))二丙二腈-连-2, 5-二噻吩} (PTz-PT)为受体，研制了基于氧化铟锡(ITO)/聚(3, 4-亚乙二氧基噻吩)-聚(苯乙烯磺酸) (PEDOT: PSS)/有源层/Al结构的倍增型全聚合物光电探测器(PM-APDs)。我们制备了P3HT : PTz-PT质量比为100 : 1、100 : 4、100 : 7和100 : 10的四种不同比例的二元PM-APDs。在黑暗条件下，由于Al的功函数和P3HT的最高已占据分子轨道(HOMO)之间存在0.8 eV的能级差距，空穴难以从铝电极注入到有源层中。有源层中的PTz-PT含量较低，缺乏连续的电子传输通道，导致有源层的电子传输能力较差。在光照条件下，由于有源层中PTz-PT含量较低，并且P3HT和PTz-PT的最低未占据分子轨道(LUMO)相差0.84 eV，光生电子会被孤立的PTz-PT捕获。Al电极附近的受陷电子会引起界面能带弯曲，实现空穴隧穿注入，从而导致外量子效率(EQE)值大于100%。在−8 V偏压下，基于P3HT : PTz-PT (100:4 wt/wt)的最优二元PM-APDs在300–1100 nm的光谱范围内具有超过100%的EQE。PM-APDs的EQE光谱形状取决于铝电极附近的受陷电子分布。通过引入聚合物聚(2-(4, 8-双(4-(2-乙基己基)环戊二烯并-1, 3-啶-1-基)苯并[1, 2-b: 4, 5-b']二噻吩-2-基)-5, 5-二氟-10-(5-(2-己基癸基)噻吩-2-基)-3, 7-二甲基-5H-4λ4, 5λ4-二吡咯[1, 2-c: 2', 1'-f][1, 3, 2]二氮杂硼嗪) (PMBBDT)作为第三组分，PM-APDs的EQE光谱形状变得更平坦。我们制备了P3HT : PMBBDT : PTz-PT质量比分别为90 : 10 : 4和80 : 20 : 4的三元PM-APDs。三元PM-APDs的EQE值在420–600 nm的范围内提高，而在630–870 nm的范围内降低。三元PM-APDs具有更平坦的EQE光谱是由于其在Al电极附近的受陷电子分布更均匀。此外，在连续光照和外加偏压的条件下，三元PM-APDs的稳定性高于最优二元PM-APDs。在−12 V偏压下，最优三元PM-APDs的EQE值在350 nm处为3500%，在550 nm处为1250%，在900 nm处为1500%。在−10 V偏压下，最优三元PM-APDs的比探测度(D_shot^*)值在520 nm处为3.7 × 10¹² Jones，在850 nm处为1.9 × 10¹³ Jones。最优三元PM-APDs在−10 V偏压下被白光连续照射170 min后，光电流为初始值的87%。我们利用最优三元PM-APDs搭建了光电容积描记(PPG)传感器并成功地测量了人体心率(HR)，测得的HR与人体正常心率相符。
