尽管TiO（2）在电子辐照下很脆弱，但Au/TiO（2）催化剂的本征结构可以用环境透射电子显微镜观察到。在反应条件下（CO/空气100 Pa），金纳米颗粒的{111}和{100}主晶面暴露出来，颗粒与TiO（2）载体呈现多边形界面，界面由平行于方向的锐边限定< 110>。
Despite the fragility of TiO (2) under electron irradiation, the intrinsic structure of Au/TiO (2) catalysts can be observed by environmental transmission electron microscopy. Under reaction conditions (CO/air 100 Pa), the major {111} and {100} facets of the gold nanoparticles are exposed and the particles display a polygonal interface with the TiO (2) support bounded by sharp edges parallel to the< 110> directions.
