Hydrogen atoms adsorbed on TiO2(110)-(1x1) surfaces have been characterized by scanning tunneling microscopy (STM) combined with electron stimulated desorption (ESD) technique. Certain amounts of H atoms are unexpectedly found on the TiO2 surfaces annealed at 900 K. Two forms of adsorption were discriminated in STM images from the different sensitivity to ESD and tentatively assigned to hydroxyl-type (O-H) and hydride-type (Ti-H) species.
通过扫描隧道显微镜（STM）结合电子激发脱附（ESD）技术对吸附在TiO₂(110)-(1x1)表面的氢原子进行了表征。在900 K退火的TiO₂表面意外地发现了一定量的H原子。在STM图像中，根据对ESD的不同敏感性区分出两种吸附形式，并初步将其归为羟基型（O-H）和氢化物型（Ti-H）物种。
