摘要

光催化分解水制取氢气对于实现避免环境污染、减缓能源危机等问题具有重要意义，开发制备简单、活性高且价格低廉的光催化剂是目前光催化制氢领域的热点研究课题之一. 本研究以具有给电子特性的芘作为电子给体单元，具有吸电子特性的二苯并噻吩砜作为电子受体单元，呋喃单元为

桥，通过三元共聚的方法，调控聚合物中受体和给体的比例，制备了一系列给体-

-受体型共轭聚合物光催化剂. 对比研究表明，聚合物中

单元的引入，可以有效地提高聚合物的共平面度，进而促进光生载流子的传输. 此外，高的共平面程度有利于提高聚合物的光吸收范围. 再者，优化电子受体和给体之间的相对比例，可以调控聚合物微结构变化，进而影响提升聚合物光催化产氢的活性. 当光催化剂给体与受体比例为1:10时，制备的Py-F-BTDO-3表现出较强的光吸收能力，在紫外-可见光照射下表现出最高的光催化产氢活性，为32.53 mmol·h

Abstract

With the rapid development of the global economy

traditional fossil fuels are becoming increasingly depleted

and the resulting environmental problems are becoming increasingly serious. Hydrogen energy has attracted considerable attention from researchers owing to its wide range of sources

high combustion heat value

and environmental friendliness. Photocatalytic decomposition of water to produce hydrogen is an effective strategy that can not only prevent environmental pollution problems

but also alleviate energy crises. At present

most of the reported photocatalysts are inorganic semiconductors and other materials

which have problems such as low photocatalytic activity and weak visible-light response. Therefore

finding photocatalysts with simple preparation

high activity

and low cost has become one of the hot research topics in the field of hydrogen production. In this article

pyrene with electron donating properties was used as the electron donor unit

dibenzothiophene sulfone with electron withdrawing properties was used as the electron acceptor unit

and furan units were used as

bridges. A series of donor-

-acceptor conjugated polymer photocatalysts were prepared by controlling the ratio of acceptor and donor in the polymer through ternary copolymerization. Comparative studies have shown that the introduction of

units in polymers can effectively improve the coplanarity of the polymer

thereby promoting the transport of photogenerated charge carriers. In addition

a high degree of coplanarity is beneficial for improving the light-absorption range of the polymer. Furthermore

optimizing the relative ratio between the electron acceptor and donor can lead to changes in the polymer microstructure

thereby affecting the enhancement of the photocatalytic hydrogen production activity of the polymer. When the ratio of photocatalyst donor to acceptor is 1:10

the prepared Py-F-BTDO-3 exhibits strong light absorption ability and shows the highest hydrogen evolution rate under UV visible light irradiation

at 32.53 mmol·h
