Effect of Precursor Selection on the Photocatalytic Performance of Indium Oxide Nanomaterials for Gas-Phase CO2 Reduction

Abstract: Nonstoichiometric indium oxide nanoparticles, In 2 O 3−x (OH) y, have been shown to function as active photocatalysts for gas-phase CO 2 reduction under simulated solar irradiation. Herein we demonstrate that the choice of starting material has a strong effect on the photocatalytic activity of indium oxide nanoparticles. We examine three indium oxide materials prepared via the thermal decomposition of either indium(III) hydroxide or indium(III) nitrate and correlate their stability and photocatalytic activity … Show more

“…Atomic‐level reactive sites can be introduced into photocatalysts via a range of strategies such as: introducing vacancies in the crystal lattice, doping single heterogeneous atoms, anchoring functional groups and loading metal complexes on the surface, and fabricating FLPs . With advances in characterization technologies and synthesis methods, researchers can design materials from atomic level to reveal fundamental photocatalytic CO 2 reduction from spatial‐and‐time perspectives using, for, e.g., high resolution transmission electron microscope (HRTEM), scanning transmission electron microscopy (STEM), and in situ technologies.…”

“…The studies are also partially fueled by the outstanding reactivity properties of its cubic In 2 O 3 counterpart (c-In 2 O 3 hereafter), which exhibits extraordinarily high CO 2 selectivities in methanol steam reforming (essentially referenced to the simultaneous largely suppressed inverse water-gas shift reactivity 13,14 ), as well as the activity in catalytic dehydrogenation of light hydrocarbons 15 and in photocatalytic CO 2 reduction. 16,17 Studies of the surface chemistry of In 2 O 3 polymorphs are also needed for understanding the mechanism of gas detection with indium oxide applied as a chemiresistive gas sensor. [18][19][20][21] As for the latter, many oxides exhibit excellent sensing properties for various gases.…”
