Oxygen vacancy (VO), the most common type of defect in metal oxides, could alter intrinsic
properties which are usually determined by crystal structures. Oxygen-deficient metal oxides …

TiO2 nanocrystals with tunable bulk/surface defects were synthesized and characterized
with TEM, XRD, BET, positron annihilation, and photocurrent measurements. The effect of …

This paper introduces a novel method for characterizing the oxygen vacancy associates in
hydrogenation-modified TiO2 by using a positron annihilation lifetime spectroscopy (PALS) …

CeO2 is a catalytic material of exceptional technological importance, and the precise role of
oxygen vacancies is crucial to the greater understanding of these oxide materials. In this …

Photocatalytic reduction of CO 2 with water by photocatalysts such as TiO 2 to produce solar
