Effects of adsorbates on the formation of doubly excited He atoms during impact of He2+ ions on Fe(110) and Ni(110) surfaces

Study on the preparation and photocatalytic oxidation properties of TiO2/nano-Fe0 photocatalysts

“…4e clearly shows the atomic planes with the lattice spacing of 2.04 Å and 3.52 Å (Fig. 4f), which corresponding to the (110) planes of a-Fe 33 and the (101) planes of anatase TiO 2 , 34 respectively. It can be inferred that a heterojunction structure is formed between nano-Fe 0 and TiO 2 nanoparticles.…”
