Quantification of photocatalytic hydrogen evolution [PDF]

Physical Chemistry Chemical Physics, 2013
A new photoreactor with defined irradiation geometry was developed and tested for the water reduction reaction using carbon nitride (“C3N4”) as a photocatalyst. The hydrogen evolution rate was investigated with a sun simulator (I = 1000 W m−2) in two different operation modes: circulation and stirring of the catalyst dispersion.

Hydrogen Evolution Catalyzed by Cobaloximes [PDF]

Accounts of Chemical Research, 2009
Natural photosynthesis uses sunlight to drive the conversion of energy-poor molecules (H(2)O, CO(2)) to energy-rich ones (O(2), (CH(2)O)(n)). Scientists are working hard to develop efficient artificial photosynthetic systems toward the "Holy Grail" of solar-driven water splitting.

Hydrogen symbioses in evolution and disease [PDF]

QJM, 2007
Hydrogen is the source of energy that unites the metabolisms and fuels the innovative potentials of all living organisms. Autotrophs use hydrogen emitted into hydrothermal vents, where symbiotic communities that share hydrogen thrive. On the surface, life developed using photons to cleave water, releasing hydrogen carried into a reverse Krebs cycle to ...

Study on Thermal Effect of Aluminum-Air Battery

Nanomaterials, 2023
The heat released from an aluminum-air battery has a great effect on its performance and operating life during the discharge process. A theoretical model was proposed to evaluate the resulting thermal effect, and the generated heat was divided into the ...

Hydrogen Evolution at Liquid–Liquid Interfaces [PDF]

Angewandte Chemie International Edition, 2009
AbstractBlowing bubbles: Hydrogen evolution by proton reduction with [(C5Me5)2Fe] occurs at a soft interface between water and 1,2‐dichloroethane (DCE). The reaction proceeds by proton transfer assisted by [(C5Me5)2Fe] across the water–DCE interface with subsequent proton reduction in DCE.

Analysis of transient characteristics for zinc-nickel single flow battery considering side reactions

International Journal of Electrochemical Science, 2021
A two-dimensional transient model of zinc-nickel single flow battery considering side reaction is developed and is used to study the effects of concentration, flow rate and applied current density on the side reaction.

Weyl Semimetals as Hydrogen Evolution Catalysts [PDF]

Advanced Materials, 2017
The search for highly efficient and low‐cost catalysts is one of the main driving forces in catalytic chemistry. Current strategies for the catalyst design focus on increasing the number and activity of local catalytic sites, such as the edge sites of molybdenum disulfides in the hydrogen evolution reaction (HER).
