Abstract
Abstract Photocatalytic processes are attractive techniques in environmental waste treatment and renewable energy generation. Herein, earth-abundant transition metal (Fe, Cu, or Ni)-impregnated one-dimensional black TiO2 nanocomposites showed upgraded photocatalytic activities in vapor decomposition and hydrogen production compared with reference samples. These results were ascribed to enhanced charge-separation efficiencies, as demonstrated by photoluminescence emission spectroscopy and hydroxyl radical density measurements, and/or enhanced visible-light-absorption efficiencies. The photocatalytic activities depended on the initial concentration of pollutant and relative humidity in the case of pollutant decomposition, whereas they depended on the type and composition of the hole scavenger in the case of hydrogen production.
