Rational Design of Transition Metal Phosphide‐Based Electrocatalysts for Hydrogen Evolution

Advanced Functional Materials, 2022
Developing efficient and inexpensive electrocatalysts for the hydrogen evolution reaction (HER) is critical to the commercial viability of electrochemical clean energy technologies. Transition metal phosphides (TMPs), with the merits of abundant reserves,

Efficient Hydrogen Evolution on Nanoscale Graphdiyne

Small, 2021
AbstractSelf‐active metal‐free graphdiyne (GDY) is used, which has a precise chemical structure, as a model carbon‐based metal‐free electrocatalyst to assess its activity in the hydrogen evolution reaction (HER) and to understand the origin of electrocatalytic performance at the atomic level.

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

Photosynthetic oxygen evolution from hydrogen peroxide

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1978
A study was made of the interactions of flash-illuminated chloroplasts with hydrogen peroxide. We conclude: 1. The oxygen precursor system can be reduced beyond the S0 state to an S-1 state, which can be oxidized to S0 by a single flash. 2. In the dark, a two-electron donation by H2O2 takes place which reduces S2 to S0 and S1 to S-1. 3.

Light-dependent hydrogen evolution by Scenedesmus

Planta, 1969
The effect of glucose and the uncoupler Cl-CCP upon hydrogen production was studied in adapted cells of Scenedesmus obliquus D3. Cl-CCP at 10(-5)M concentration completely inhibited the evolution of H2 in the dark and increased the apparent rate of H2 evolution in the light.

Hydrogen Evolution Reaction from EDTA Solutions

Materials Science Forum, 2002
An attempt was made to investigate the mechanism and kinetics of hydrogen evolution reaction on zinc and platinum wire electrodes from solutions containing ethylene diamine tetraacetic acid (EDTA). EDTA is a tetra-basic acid whose dissociation covers a wide range of pH, with a betaine structure in solutions.
