以可再生能源为能量来源,在水溶液中进行的光(电)催化CO_(2)还原生成高附加值化学品和燃料是解决能源危机与环境污染的有效途径之一.CO是一种简单却很重要的CO_(2)还原产物,它可以作为水煤气变换反应与费托合成的重要原料.具有较高CO选择性的贵金属纳米颗粒催化剂(如Au和Pd)一直受到研究者的广泛关注.一般来说,金属颗粒催化剂的催化性能与粒径大小密切相关,即所谓的粒径效应.然而在实际的理论计算研究中,由于受到计算能力的限制,催化剂模型都仅局限于简单的周期性模型或小的金属团簇模型,无法准确描述真实颗粒上复杂的反应位点的性质,导致了对催化行为的误解.因此,建立更加真实的颗粒模型对探究纳米颗粒催化剂上活性位点的性质,解释其粒径效应至关重要.本文旨在阐述Au与Pd纳米颗粒催化剂不同活性位点上CO_(2)还原反应与产H2副反应的竞争机制,并解释Au与Pd纳米颗粒催化剂在CO_(2)电还原中表现出不同粒径效应的原因.本文基于密度泛函理论,采用VASP软件,BEEF-vdW泛函进行计算.分别建立了原子数为55,147,309和561的颗粒模型和高CO^(*)覆盖度模型,避免了传统周期性模型的局限性,探究了金属颗粒催化剂不同反应位点上的CO选择性.结果表明,对于颗粒模型来说,(100)位点对CO的选择性优于边缘位点;但对于周期性模型来说,Au(211)对CO的选择性则优于Au(100).产生这种反差的主要原因在于Au颗粒的边缘位点对H*的吸附过强.通过对比,我们直观地展现了颗粒模型上平面位点和Edge位点与相对应的周期性模型上CO选择性的区别,突出了模型选择对揭示活性位点性质的重要性.在此基础上,通过计算理论CO法拉第效率,发现Au颗粒随着粒径的减小,CO选择性降低,与实验的趋势一致.对于Pd催化剂来说,低覆盖度模型无法正确预测活性位点的性质;而高CO覆盖度的情况下,Pd颗粒的边缘位点对COOH^(*)吸附能更强,这是导致边缘位点上CO选择性更高的主要原因.同样通过计算理论CO法拉第效率,发现随着粒径的减小,Pd颗粒上CO选择性升高.本文不仅成功揭示了Au与Pd颗粒催化剂上活性位点的性质,对粒径效应做出了合理解释,也强调了合理的计算模型是理论研究的基础.

NH_3选择催化还原(NH_3-SCR)是一种优异的NOx脱除技术,当前该技术中使用最广泛的商业催化剂为V_2O_5-WO_3(WO_3)/TiO_2。由于这种催化剂中含有毒的V﹑且具有强的SO_2氧化能力以及高的操作温度窗口(350～400℃)等原因,并不适用于低温条件下使用。因此,发展一种在低温下具有较高活性以及对环境友好的催化剂受到了研究者们的广泛关注。近些年,人们发现Ce基氧化物催化剂具有独特的氧储存和释放以及氧化还原性能,在NH_3-SCR反应中表现出优异的低温催化活性,被认为是SCR反应催化剂的候选者。在此本文详细地阐述了Ce基氧化物催化剂用于低温NH_3-SCR反应过程中的研究进展(活性以及抗硫性能)和存在的缺点,为未来高效Ce基氧化物催化剂的研发提供指导。

上转换纳米颗粒(UCNPs)是由某些稀土元素掺杂于固体晶格中所构成的纳米颗粒,它是一类能够通过多光子吸收机制吸收近红外光子而发射可见光子的新型荧光材料。肿瘤传统的临床诊断技术,如核磁共振成像、超声、荧光成像等,虽已运用多年但也有其缺点,因此我们需要一种新型材料来弥补传统诊断技术的不足,得到更多有用的诊断信息。近年来随着对UCNPs深入研究,发现其优点众多:生物相容性好、毒性低、稳定性好,还能与配体联接拥有更多特性,因此成为了研究热点。有不少研究更是将UCNPs运用于肿瘤的各种诊断技术中,来提升成像对比度、减少副作用、延长成像时间等,为精确诊断提供了更加完善的信息,并取得了一定的效果。本综述集中就UCNPs在肿瘤临床诊断中的研究进展,并对其在诊断领域的未来发展趋势进行小结。
