Abstract

This work deals with Cu-modified 1DTiO microrods (MRs) and their surface properties. The pristine lyophilized precursor Cu_1DTiO, prepared by an environmentally friendly cryo-lyophilization method, was further annealed in the temperature interval from 500 to 950 °C. The microstructure of all samples was characterized by electron microscopy (SEM/EDS and HRTEM/SAED), X-ray powder diffraction (XRD), infrared spectroscopy, simultaneous DTA/TGA thermoanalytical measurement, and mass spectroscopy (MS). Special attention was paid to the surface structure and porosity. The 1D morphology of all annealed samples was preserved, but their surface roughness varied due to anatase-rutile phase transformation and the change of the nanocrystals habits due to nanocavities formation after releasing of confined ice-water. The introduction of 2 wt.% Cu as electronically active second species significantly reduced the direct bandgap of 1DTiO in comparison with undoped TiO and the standard Degussa TiO_P25. All samples were tested for their UV absorption properties and H generation by PEC water splitting. We presented a detailed study on the surface characteristics of Cu doped 1DTiO MRs due to gain a better idea of their photocatalytic activity.

摘要

这项工作涉及铜改性的一维二氧化钛微棒（MRs）及其表面性质。通过环境友好的冷冻干燥法制备的原始冻干前驱体Cu_1DTiO，在500至950°C的温度区间内进一步退火。所有样品的微观结构通过电子显微镜（SEM/EDS和HRTEM/SAED）、X射线粉末衍射（XRD）、红外光谱、同步DTA/TGA热分析测量和质谱（MS）进行表征。特别关注表面结构和孔隙率。所有退火样品的一维形态得以保留，但由于锐钛矿-金红石相转变以及受限冰水释放后纳米腔形成导致纳米晶体习性改变，其表面粗糙度有所变化。与未掺杂的TiO和标准德固赛TiO_P25相比，引入2 wt.%作为电子活性第二物种的铜显著降低了一维TiO的直接带隙。对所有样品进行了紫外吸收性能测试以及通过光催化水分解产氢测试。我们对铜掺杂的一维TiO微棒的表面特性进行了详细研究，以便更好地了解其光催化活性。
