Facet dependent catalytic activities of anatase TiO2 for CO2 adsorption and conversion

Crystal Facet-Dependent CO2 Photoreduction over Porous ZnO Nanocatalysts

“…The breakthrough was made by Lu and co-workers, who prepared single anatase TiO 2 crystals with 47% of highly reactive {001} facets using hydrofluoric acid as the capping agent . Later, a number of works on TiO 2 have been reported about its facet engineering. , Besides the TiO 2 , other semiconductor catalysts can also show facet-dependent photocatalytic activity, such as Ag 3 PO 4 , BiOCl, SrTiO 3 , WO 3 , BiVO 4 , − and Bi 2 MoO 6 . As an important II–VI semiconductor, ZnO is a direct band gap semiconductor with a band gap of about 3.2 eV.…”

Localized thermal spike driven morphology and electronic structure transformation in swift heavy ion irradiated TiO2 nanorods

“…Our previous analysis on TiO 2 tells that with these sets of parameters, the lattice parameters for the case of anatase TiO 2 match with that of the theoretical and experimental reports. 60,61 The rutile TiO 2 crystallizes in a tetragonal structure with P4 2 /mnm (space group #136). Each unit cell contains two formula units of TiO 2 , in which each Ti atom is coordinated with six O atoms and each O atom to three Ti atoms, as shown in Fig.…”

Role of Anions in the Synthesis and Crystal Growth of Selected Semiconductors

“…Furthermore, the morphology of a catalyst is crucial since factors such as the size and shape of particles, the energy associated with facets, coordination of atoms, and the presence of protective ligands can mainly influence its catalytic efficiency ( Cao et al, 2016 ; Guo et al, 2018 ; Lin et al, 2019 ; Mishra and Nanda, 2020 ). In a recent study, Chiu et al (2012) conducted facet-dependent catalytic activity of Au nanocubes, octahedral, and rhombic dodecahedra towards 4-nitroaniline.…”
