研究亮点：

采用离子注入法制备了C/N共掺杂TiO2纳米棒阵列，可见光下光解水电流密度高达0.76 mA/cm2，远高于TiO2的3 μA/cm2。450 nm的IPEC可达14.8%。

对于水解离反应，光电化学法相较于光化学和光伏电解技术具有更直接且成本更低的优势。TiO2自1972年经Fujishima和Honda等人发现可以经光电化学解离水之后，便受到了广泛研究。但是受限于TiO2的禁带宽度问题，在光电转换中往往只有紫外光可以被有效利用。

为增加能量利用率，过去几十年中科研工作者一直在尝试改变其带隙。其中最广泛使用的方法是在TiO2中掺杂其他元素，如B, C, N, S等。相较于单种元素掺杂，多元素的共掺杂在一定程度上效果更好。如C，N共掺杂就被认为潜在的最佳组合。

但是常用的水热或者高温老化等方法面临诸多问题，如难以控制掺杂量、掺杂比例和元素分布等，使得所得到的共掺杂材料的光电转换效率并不高。在半导体产业中，离子注入法常用于改变半导体理化性质和电子结构，这种方法具有简便可控的优势，可以高效地实现一种或多种金属和非金属离子的可控掺杂。

有鉴于此，武汉大学肖湘衡和中科大王功名团队合作，利用离子注入法在TiO2中引入大量N-Ti键和Ti3+物种，大幅提升了可见光范围的光吸收和电子分离效率。

综上，本研究报道了一种将高效的离子注入法，在TiO2阵列上实现了C/N的可控共掺杂，将TiO2点石成金，大幅提升其可见光电解水的效率。作者认为该方法不仅适用于TiO2，在其他类型的材料上也具有较大的应用潜能。

武汉大学肖湘衡教授、浙江大学杨士宽教授和武汉大学中南医院汪付兵教授受到分子印迹的启发，设计了一种新的具有体“热点”的体增强拉曼散射（VERS）基底。该基底由底部具有纳米锥孔的微米尺寸碗阵列组成，纳米锥孔的直径可以根据病毒的尺寸进行调节。

该工作成功的解决了常规SERS基底在检测病毒时，病毒取向对拉曼信号不可重复性的影响。使用VERS基底，单个病毒的拉曼信号的完整性和重复性得到了极大的改善，这一成果在疾病诊断和监视，生物医学领域，以及临床治疗方面都具有重要的应用前景。该研究工作为SERS基底在检测大尺寸分析物方面提供了一种重要的思路和方法。

通过电能或者太阳能等清洁能源驱动水分解生成氢气是一种十分简便、高效的氢能制取途径，有助于无碳能源体系的建立和“碳达峰、碳中和”可持续发展目标的实现。为了实现水分解制氢技术在工业上的大规模应用，开发高效、耐用和低成本的催化剂以取代传统的贵金属催化剂是当前研究的重点和难点所在。
二氧化钨（WO2）由于具有廉价、安全无毒以及独特的物理化学性质等诸多优势而被作为一种重要的功能材料应用于多个领域。更有趣的是，WO2晶体结构中除了具有传统氧化物中金属-氧（W-O）配位外还存在较强的金属-金属（W-W）配位，表现出类金属的特性。其优异的电子传输能力十分有利于电子参与的水分解反应，具有作为高效水分解催化剂或催化剂载体的潜力。然而，W-W配位虽然赋予WO2良好的电子输运能力，但与此同时W-W位点对氢的强吸附严重阻碍了氢在催化剂表面的解吸过程，导致在实际催化反应中其析氢活性并不理想。
近日，武汉大学肖湘衡教授团队与中国科学技术大学王功名教授合作报道关于金属氧化物中d-d轨道配位结构精细调控的最新研究成果。研究团队以具有金属性的WO2作为模型材料，深入研究了WO2中W-O双八面体中金属与金属原子之间d-d轨道相互作用本质并且提出了金属-金属轨道耦合调控策略。理论计算发现通过调控双八面体中反键轨道中的电子填充度可以有效地调节金属-金属配位强度，通过使用具有更高d带电子填充的M杂原子（M = Fe、Co、Ni、Cu等）取代W原子可以梯度削弱W-M键从而实现其d-d轨道配位结构的精细调控。进一步计算结果显示W-M活性位点对于氢吸附强度也得到相关性的调节，并且Ni-M配位表现出最优的氢吸附强度。

      在此理论指导的基础上，研究团队通过化学掺杂制备了一系列具有过渡金属杂原子调控的WO2催化剂。XRD，HRTEM，EDS等相关表征计算结果显示样品呈现良好的纳米线形貌以及均匀的替代位掺杂。进一步通过XANES和EXAFS等表征测试对Ni掺杂引起的WO2中局部构型的变化进行深入表征分析，测试结果显示由于WO2中Ni原子的引入导致微观配位结构的变化，相对于原始WO2中的W-W配位，Ni-WO2中的W-W/Ni配位呈现出更大的配位键长，这一结果吻合理论计算中的结果分析。
      基于前述对催化剂晶体结构和配位调控的研究基础，研究人员通过三电极体系对系列过渡金属杂原子调控的WO2催化剂碱性HER催化活性进行评估测试。测试结果显示，相对于WO2，随着过渡金属M杂原子（M = Fe、Co、Ni、Cu等）引入对W-M活性位点配位强度和氢吸附能力的梯度调控，其HER反应活性也呈现出相关性变化，并且Ni-WO2样品表现出最为优异的HER反应活性。其在-10 mA/cm2的电流密度下所需过电位仅为41 mV，并且在超过100小时的稳定性测试中表现出优异的性能保持性，远优于单纯的WO2（330 mV），代表了迄今为止最佳的钨基水分解析氢（HER）催化剂之一。
      综上，该工作对金属氧化物中金属-金属耦合配位结构的作用本质进行了深入研究，并且该金属-金属轨道耦合调控的策略可以为其他过渡金属氧化物微观配位的精细调控和相关应用设计提供有价值的见解和参考意义。

硫代磷酸铁（FePS3）是一种典型的低成本层状金属硫代磷酸盐（MTPs），由FeS6和P2S6多面体组成，通过共享界面提供了丰富的金属铁中心和非金属P中心位置，可以作为整体电解水的潜在催化剂，受到越来越多的关注。然而，在最近的研究中，MTPs的性能在实际电解方面还远远不能令人满意。低碱性水电解过程中氧的吸附和脱附动力学缓慢，这本质上是由FePS3的固有电子结构特性决定的。由于空间效应，FePS3中间层Fe 3dz2杂化轨道和羟基/水存在较小的相互作用，实际阻碍了铁原子的吸附。而这些含氧中间体在电负性高的磷(P)上的吸附作用也限制了催化活性。受上述启发，合理调整表面催化位点的电子结构，使其具有高效的碱性水裂解催化活性是非常理想的，但同样具有挑战性。
      基于此，武汉大学肖湘衡教授等人报道了一种通过锚定原子分散的金属原子来调整FePS3纳米片(NSs)的表面电子结构的一种方法。单原子Ni-FePS3的强电子耦合效应促进了铁原子向附近的镍s键的电子聚集，增强了Ni和S位点的电子转移，平衡了氧的吸附能力，增强了水的吸附和解离过程，加速了相应的析氧反应(OER)和析氢反应(HER)。
   本文要点：
      1) 理论预测确定可能的化学构型，并评估了HER过程中能量势垒的相应变化：Ni取代FePS3的Fe位点后，Fe原子的电子倾向于向相反的Ni-S键流动，使得Fe的电子密度较低，S的负电荷较多；随着S原子的电荷从0.38增加到0.45，Ni-S键处的电荷分布也发生了变化
      2) 通过简易浸渍吸附和进一步的氩气气氛退火制备了由原子分散的金属原子锚定的FePS3 NSs，在FePS3上引入Ni后没有产生新的相，Ni在FePS3 NSs上是均匀分布的。Ni-FePS3中较短的Fe-S键是由于引入的Ni原子促进了电子从Fe原子聚集到附近的Ni-S键，从而加强了Fe和S原子之间的电荷相互作用。
      3) Ni-FePS3 NSs/C、Co-FePS3 NSs/C和Pd-FePS3 NSs/C在10 mAcm-2电流密度下的的OER过电位分别为287、320和400 mV，远低于FePS3 NSs/C (474 mV)。在HER方面也表现出有意的性能。
