Highly enhanced photocatalytic hydrogen evolution activity by modifying the surface of TiO₂ nanoparticles with a high proportion of single Cu atoms

Abstract

Single-atom photocatalysts have received a lot of attention owing to their high catalytic activity.

Single-Atom Pd Supported on TiO2 for the Photocatalytic Production of Hydrogen

“…Notably, the presence of Pd dopant in the samples does not exert any influence on their crystalline structure. It is worth mentioning that the low content of Pd in samples is below the detection limit of XRD, hence resulting in the absence of corresponding diffraction peaks …”

Recent Progress of Single‐Atom Photocatalysts Applied in Energy Conversion and Environmental Protection

“…During the preparation of SACs, metal atoms must constantly migrate on the support to control their coordination to anchor sites. [81,82] Therefore, designing and synthesizing highly efficient SACs with strong robustness remains a crucial challenge. In general, the preparation methods of SACs can be divided into bottom-up and top-down types.…”

Research progress of MIL-125 and its modifications in photocatalytic hydrogen evolution

“…Cu single atoms presented very superior photocatalytic activity. 105 Cu single atoms with unsaturated coordination loaded in TiO 2 with oxygen vacancies, 106 and the adsorption of water molecules was facilitated and the hydrogen evolution activity of the photocatalyst was significantly improved. Zhang et al 95 introduced Cu into MIL-125 and then derived it into TiO 2 with anchored Cu single atoms, and it significantly enhanced the hydrogen evolution activity and the photocatalyst had excellent stability.…”
