The Zn-Ti distances are 0.369 nm and 0.335 nm for the single-corner adsorption mode and double-corner adsorption mode, respectively. Therefore, the EXAFS fitting data, R1=0.371 nm, R2=0.332 nm, can be well distinguished for SC and DC mode respectively. The calculation results also showed that the optimized Zn-O average distance of Zn-O tetrahedron is about 0.200 nm, which agree with the EXAFS results.
