Ferromagnetism of cobalt-doped anatase TiO$_2$ studied by bulk- and surface-sensitive soft x-ray magnetic circular dichroism

, 2012
We have studied magnetism in anatase Ti$_{1-x}$Co$_x$O$_{2-\delta}$ ({\it x} = 0.05) thin films with various electron carrier densities, by soft x-ray magnetic circular dichroism (XMCD) measurements at the Co $L_{2,3}$ absorption edges.

Asymmetric‐Coordinated Indium Single Atoms for Highly Selective Photocatalytic CO2 Reduction

Carbon Energy, EarlyView.
This work develops an indium single‐atom photocatalyst (In‐NTO) featuring unique Inδ⁺–N3O2 coordination sites for highly selective CO2 photoreduction. The specific atomic interface steers the reaction pathway exclusively toward CO (95.9% selectivity) by lowering the overall energy barrier and converting the critical *CO protonation step from ...

Metal-to-insulator transition in anatase TiO2 thin films induced by growth rate modulation

, 2012
We demonstrate control of the carrier density of single phase anatase TiO2 thin films by nearly two orders of magnitude by modulating the growth kinetics during pulsed laser deposition, under fixed thermodynamic conditions.
