Toward Practical High‐Areal‐Capacity Aqueous Zinc‐Metal Batteries: Quantifying Hydrogen Evolution and a Solid‐Ion Conductor for Stable Zinc Anodes

Advances in Materials, 2021
The hydrogen evolution in Zn metal battery is accurately quantified by in situ battery–gas chromatography–mass analysis. The hydrogen fluxes reach 3.76 mmol h−1 cm−2 in a Zn//Zn symmetric cell in each segment, and 7.70 mmol h−1 cm−2 in a Zn//MnO2 full ...

Pyrene: Hydrogenation, hydrogen evolution, and π-band model

The Journal of Chemical Physics, 2011
We present a theoretical investigation of the hydrogenation of pyrene and of the subsequent molecular hydrogen evolution. Using density functional theory (DFT) at the GGA-PBE level, the chemical binding of atomic hydrogen to pyrene is found to be exothermic by up to 1.6 eV with a strong site dependence. The edge C atoms are found most reactive.

Amorphization of MXenes: Boosting Electrocatalytic Hydrogen Evolution

Small, 2023
AbstractThe emergence of amorphous 2D materials has opened up new avenue for materials science and nanotechnology in the recent years. Their unique disordered structure, excellent large‐area uniformity, and low fabrication cost make them important for various industrial applications. However, there have no reports on the amorphous MXene materials.

Hydrogen evolution by several algae

Planta, 1970
Out of 33 strains of unicellular algae examined, H2 evolution was observed only in species of Chlamydomonas, Chlorella and Scenedesmus. While the photoevolution of H2 by these algae was generally stimulated both by an organic substrate and by the uncoupler CCCP(1), response to DCMU varied. On the basis of the response to DCMU, it was concluded that the
