Determining the role of redox-active materials during laser-induced water decomposition
Abstract
The decomposition of water and the formation of molecular hydrogen, oxygen, and hydrogen peroxide during laser ablation of redox-active materials is systematically studied and related to the ablation rate and oxidation degree of the nanoparticles.

Density-dependent productivity, or volume productivity, is useful to compare the productivity of different materials with different densities because high-density materials usually show higher mass productivity than low-density materials.
“This approach is useful to compare the productivity of different materials with different densities since high-density materials usually show higher mass productivity compared to low-density materials.86”

The standard reduction potential of elements influences the volume of gas formed.
“The authors suggest that the standard reduction potential (E 0 ) of these elements influences the volume of gas formed.”

Less-noble metals such as Al produce the largest gas volume, followed by titanium, iron, and copper, while Au, Pt, and Ag produce the lowest gas formation.
“The results show that less-noble metal such as Al produces the largest gas volume, followed by titanium, iron, and copper, respectively, while less oxidation-sensitive metals such as Au, Pt, and Ag produce the lowest gas formation (Fig. 10c).”

Formation of more gas bubbles for these elements results in lower ablation yield due to shielding of the incoming laser beam.
“The formation of more gas bubbles for these types of elements results in a lower ablation yield due to the shielding of the incoming laser beam (Fig. 10d).86”

Elements with negative standard reduction potentials readily react with water vapor to form oxides and molecular hydrogen as a side product.
“In the PLAL system, the elements with negative E 0 values readily react with water vapor to form oxides and molecular hydrogen as a side product.86”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
