In the View of Electrons Transfer and Energy Conversion: The Antimicrobial Activity and Cytotoxicity of Metal‐Based Nanomaterials and Their Applications

“…[ 72 ] Under certain conditions ( Figure B‐a–c), the catalytic antibacterial process of Ag‐based materials is activated and exhibits the LSPR effects, providing extra hot‐carriers and producing ROS such as ·O 2 − , ·OH, and 1 O 2 . [ 192 ] Hu at al. reported that the photocatalytic ROS is induced by Ag nanoparticles of different sizes under sunlight illumination.…”

Fluorinated carbon encapsulated NiO cluster/TiO2 nanotubes as a robust photocatalyst for hydrogen evolution

“…13 Commonly, the electrons ow from the low work function semiconductor to the semiconductor of high work function. [13][14][15][16] The particle size of the cocatalyst signicantly impacts the specic surface area, electronic structure and the number of surface active sites. 17,18 It also effectively changes the energy level and the work function alignment at the catalyst/cocatalyst interface, and greatly impacts the surface binding property of the composite.…”

A highly durable AgOx cluster/mesoporous TiO2 photocatalyst with synergistic effects induced superior H2 evolution and CO2 reduction

“…5 When using a cocatalyst to facilitate charge separation to decrease the charge recombination, construction of a suitable barrier height at the catalyst/cocatalyst interface is another challenge, particularly for the noble metal co-catalyst with a high work function. 6 During the reaction process, the energy barriers for reactant adsorption on the catalyst surface, the reaction, and the release of the products from the catalyst surface are also governing factors for the success of the photocatalytic reaction. 7,8 To date, demonstration of long-term stability and durability of the photocatalyst is scarce, but needed for commercialization.…”
