摘要:

氢能因能量密度高、燃烧产物零碳排放, 被认为是支撑未来低碳能源体系的重要载体. 半导体光催化析氢能够直接将太阳能转化为可储存的氢能化学燃料, 其中硫化镉(CdS)因可见光响应强、带隙约为2.4 eV, 且导带位置较负而受到广泛关注. 然而, 本征CdS仍面临光生载流子快速复合和严重光腐蚀两大瓶颈, 限制了其长期高效应用. S型异质结通过调控界面电荷转移路径, 在保留强还原电子的同时消耗CdS中的腐蚀性空穴, 为提升CdS基光催化析氢活性与稳定性提供了重要思路.
本文围绕CdS基S型异质结光催化析氢, 系统总结了其机理演化、界面设计、实验表征与性能提升规律. 首先, 本文梳理了CdS基异质结由传统II型、液相Z型、全固态Z型和直接Z型向S型机制发展的过程. 与II型异质结中电子和空穴分别迁移至较低还原能力和较低氧化能力能带不同, S型异质结以费米能级匹配为热力学基础: CdS通常作为还原光催化剂, 具有较小功函数和较高费米能级; 与功函数较大的氧化光催化剂接触后, 暗态下自由电子由CdS迁移至对方组分并形成由CdS指向氧化光催化剂的内建电场及相应能带弯曲. 光照时, 该内建电场、能带弯曲和界面库仑作用协同促进低还原能力电子与CdS价带空穴在界面定向复合, 从而保留CdS导带中的强还原电子用于质子还原, 同时减少空穴对晶格S2-的氧化. 其次, 本文归纳了多种界面构筑策略: CdS量子点可将体相扩散距离缩短至纳米尺度, 并通过量子限域增强还原能力; 2D/2D面接触结构可扩大界面接触面积、降低电荷转移阻力并建立均匀内建电场, 原子级Cd-N, Cd-S, Ti-S和Ni-S等界面化学键则可建立轨道耦合通道. 最后, 本文提出S型机制不能依赖单一证据判断, 而应结合紫外-可见光光谱、紫外光电子能谱、价带谱和Mott-Schottky确定能带结构, 利用原位X射线光电子能谱/X-射线吸收光谱、开尔文探针力显微镜或表面光电压跟踪光照下电子流向, 通过原位电子顺磁共振识别强氧化还原活性物种, 并借助时间分辨光致发光谱和飞秒瞬态吸收光谱揭示载流子寿命与超快转移动力学.
未来CdS基S型异质结仍需面向真实反应环境发展原位表征, 实现载流子迁移的时空双重追踪, 并进一步拓展无牺牲剂串联反应、规模化制备、Cd泄漏控制和长期稳定性研究. 本文建立的界面设计与电荷转移动力学表征方法, 可为高效、稳定、可持续的人工光合作用体系开发提供重要指导.

Abstract:

Cadmium sulfide (CdS) is a promising visible-light-responsive photocatalyst for solar-driven hydrogen (H2) production owing to its suitable band structure, yet pristine CdS generally exhibits only moderate photocatalytic activity because of rapid charge-carrier recombination and severe photocorrosion. Step-scheme (S-scheme) heterojunctions offer a structural solution to circumvent these bottlenecks. By driving the directional recombination of less reactive charge carriers at the physical interface, the S-scheme mechanism preserves the charge carriers with the strongest redox potentials. This specific pathway maintains robust H2 evolution kinetics while transferring oxidizing holes away from CdS, effectively mitigating self-oxidation. This review systematically summarizes recent advancements in CdS based S-scheme heterojunctions. We elucidate the fundamental thermodynamic principles and evaluate rational interfacial design strategies across diverse structural dimensions. Furthermore, we highlight the rigorous experimental evidence required to verify charge transfer pathways using advanced dynamic characterization techniques. Finally, we outline current challenges and future directions toward practical applications.
