研究方向
光与物质的相互作用是自然界普遍存在的现象。太阳能转化就是典型的涉及光与物质相互作用的过程。载流子的产生、分离、传递和表面化学反应是光伏和光催化这两个太阳能转化过程中最核心的问题，它们共同决定了光-电和光-化学转化的效率。尽管报道的效率在不断刷新，这其中仍然有很多兼具挑战性与启发性的科学问题。比如如何提高载流子的分离和传递效率？是否能够捕获“热”载流子以提高能量转换效率？光催化反应的基元步骤是什么？如何探测光催化反应的过渡态？载流子传递与界面的电子结构密切相关，光催化反应也发生在界面。避免从实验结果进行经验性的推断，用自行研制的先进物理化学实验方法直接对费米面附近的基态和激发态电子结构、载流子动力学以及表面化学动力学从时间、能量和动量上进行探测是我们的主要研究内容，结合理论计算，揭示表界面微观结构与电荷以及化学动力学之间的关联，从原子分子水平理解太阳能转化中的物理和化学过程。
1.光催化反应基元步骤
应用光电子能谱、程序升温脱附谱、扫描隧道显微镜等基于超高真空的表面分析技术，结合理论计算，从吸附结构、反应位、反应产物等方面揭示单晶材料模型体系中光催化反应的路径和动力学；比较超高真空条件和近常压条件下光催化反应基元过程的异同；应用金属纳米颗粒材料表面局域等离激元激发研究CO2还原等与能源环境密切相关的化学过程。
2.表界面超快电子动力学
表界面电子结构与光吸收、电荷分离与扩散、界面电荷传递密切相关，对理解太阳能转化过程至关重要。光电子能谱是测量电子结构最直接的手段之一。同时由于光电子的逃逸深度很浅，光电子能谱方法是表面敏感的技术。光电子发射过程满足能量和水平动量守恒，测量其动能和水平动量的对应关系，就能够获得材料的能带结构。将超快激光与光电子能谱方法结合，用泵浦-探测方法可以实现对固体材料表界面的电子结构及其动力学从时间、能量和动量方面的刻画。
3.表界面超快化学动力学
对于深能级如吸附质分子轨道和高动量空间的超快电子动力学的测量，常规非线性过程产生的超短脉冲，其光子能量（hv=6eV）已经不能满足实验要求，需要更高光子能量的超快光源。通过自行研制的基于高次谐波产生技术的时间分辨角分辨极紫外光电子能谱装置（hv=42eV），研究表界面电子和化学反应超快动力学，如光催化体系中动量分辨的瞬态能级匹配、金属纳米材料等离激光光催化反应的中间体。
过渡态的直接探测是化学反应研究的“圣杯”。过渡态浓度低、寿命短，对它的实验探测需要极高灵敏度的超快技术。自由电子激光技术的发展为该领域研究提供了前所未有的机遇。X射线自由电子激光具有超高亮度、超短脉冲和元素识别的特点。借助上海X射线自由电子激光的建设，我们将利用时间分辨X射线光谱技术对光催化反应过渡态的电子结构进行直接的实验探测，结合理论计算，明确过渡态结构。

近期工作成果展示
1.实现金红石TiO2中Ti3+缺陷位点的选择性激发
位点选择激发(Site-Selective Excitation; SSE)是操控单分子反应动力学、分析晶体结构、调控材料发光、研究蛋白质结构和相互作用的重要手段。SSE通常是利用物质局部振动/电子结构的不同通过调谐激发光波长来实现的。模型材料中的位点选择激发鲜有报道。金红石TiO2是光催化和表面科学研究领域的模型体系，在前期揭示Ti3+ 3d轨道在TiO6八面体中劈裂形成带隙态和激发态的基础上，研究人员利用衬底晶面、衬底晶向和激发光偏振相关的双光子光电子能谱，明确了金红石TiO2中Ti3+ 3d→3d的跃迁偶极矩沿着TiO6八面体的长轴([110]和[1-10])，证明了该材料中Ti3+缺陷位点可通过调谐激发光偏振来选择性激发。特别是金红石TiO2(110)表面的两种Ti3+位点，选择性激发为后续研究原子位点识别的表面物理和表面化学过程以及主动调控奠定了基础(JACS Au, 2024, 4, 491)。
2.阐明表面结构对CH3OH/TiO2体系光催化反应动力学调控的机制
TiO2(110)表面Ti5c位甲氧基负离子的光化学活性比甲醇高得多，但是甲醇在TiO2(110)表面的光催化反应动力学与其吸附结构密切相关的深层原因并不清楚。结合紫外光电子能谱(UPS)和DFT计算，我们发现反应动力学差异来源于吸附质对界面电子结构的调控以及对空穴的捕获能力。有效的电荷分离以及热力学允许的界面空穴传递使得甲氧基负离子在TiO2表面具有光化学活性，而甲醇分子则不反应。使用脉冲激光激发光化学反应可能在高峰值功率条件下促进甲醇转变成甲氧基负离子，从而表现出光化学活性(ACS Catalysis, 2021, 11, 2620)。
Pt助催化剂是光催化中常用的促进电荷分离的电子受体，此外Pt还可以提供反应场所，降低还原反应势垒，从而提高光催化产氢效率。应用程序升温脱附谱(TPD)和UPS首次从表面科学角度研究了CH3OH在Pt/TiO2(110)模型体系表面的光化学，发现Pt能通过调控界面电子结构、促进甲醇转化成甲氧基负离子、降低产物H的脱附温度来大幅度提高甲醇的光催化氧化速率(ACS Catalysis, 2019, 9, 286)。
3.揭示Ti3+电子结构及其对TiO2光吸收影响的原因
作为光催化、太阳能转化等诸多研究领域的模型催化剂，二氧化钛容易被还原，形成Ti3+并伴随Ti 3d性质带隙态的出现。带隙态是TiO2中d→d跃迁的基态电子态，与光吸收密切相关，如还原性TiO2呈蓝色以及Ti3+自掺杂实现可见光催化。相比于对带隙态的透彻研究，对激发态的了解非常有限。结合双光子光电子能谱和理论计算，发现TiO2(110)费米能级以上2.5±0.2 eV处的电子激发态是一个与Ti3+相关的固有电子态，并且明确了带隙态的dxy属性和激发态的dxz/dyz/dz2属性。由于带隙态和激发态都有很宽的分布(>0.5 eV)，这样一个d-d跃迁将光吸收从紫外波段扩展到了可见波段。该成果一方面澄清了TiO2(110)费米能级以上2.5±0.2 eV处电子激发态的物理本质，另一方面解释了Ti3+自掺杂对TiO2吸收光谱的扩展进而实现可见光催化的原因，同时为研究金属氧化物的基态和激发态电子结构提供了一个范例(J. Am. Chem. Soc., 2015, 137, 9146)。
4.首次从单分子水平观测到甲醇在TiO2(110)表面的光催化解离
TiO2光催化分解水的效率非常低，但是加入牺牲试剂甲醇能大大提高产氢效率。虽然甲醇在这个体系中作为空穴捕获体被大家熟知，但是甲醇在TiO2表面的光物理和光化学性质缺少原子分子层面的认识。应用自行发展的实时双光子光电子能谱，在单层甲醇覆盖的TiO2(110)表面发现了一个位于费米能级以上2.4 eV的光诱导的激发电子态，并结合扫描隧道显微镜技术(STM)和密度泛函理论计算(DFT)，发现该激发态与甲醇的解离密切相关，首次从单分子水平给出了甲醇在TiO2(110)表面Ti5c位光催化解离的直接证据(Chemical Science, 2010, 1, 575)。
该工作一方面明确了甲醇在TiO2(110)表面Ti5c位以分子形式而不是解离形式吸附，进而通过光催化解离，消除了多年的争议。Mike A. Henderson博士在其综述文章中(Surface Science Reports, 2011, 66, 185)评价该工作是对甲醇在单晶TiO2表面光化学的第一次机理性研究；该工作被Science (2010, 330, 12)以Breaking Methanol为题highlight，同时被Chemistry World评为Cutting Edge Chemistry in 2010 (http://www.rsc.org/chemistryworld/News/2010/ December/2112101.asp)。
