The objective of developing a prototype or scale model of production of hydrogen and oxygen through the electrolysis process of water is to generate an alternative with a sustainable approach, which proposes the supply or source of energy initially with a direct current power source replaceable in the future by a photovoltaic solar system.
Enhancing Hydrogen Evolution Electrocatalytic Performance in Neutral Media via Nitrogen and Iron Phosphide Interactions
May 6, 2021
Researchers developed a facile strategy to stabilize the structure of metal phosphides during hydrogen evolution reaction (HER) and promote intrinsic catalytic activity by introducing N atoms into the structure of the FeP material as HER electrocatalysts for neutral media.
Recent Advances Of Single-Atom Electrocatalysts For Hydrogen Evolution Reaction (HER)
June 21, 2021
Researchers introduced the basic mechanism of electrochemical HER, explained the leading methods used in the synthesis strategies of single-atom electrocatalysts (SAECs), and summarized recent advances in using these SAECs towards HER from the aspect of the local structural regulation and the support coupling effect by precise tuning of metal anchoring sites and supports.
Efficient Alkaline Hydrogen Evolution Electrocatalyst
January 4, 2021
Researchers realized a NiCo(OH)x-CoyW catalyst with a bush-like heterostructure via gas-template-assisted electrodeposition, followed by an electrochemical etching-growth process, which ensured a high active area and fast gas release kinetics for a superior hydrogen evolution reaction.

April 27, 2021
Researchers designed an outstanding HER electrocatalyst, highly dispersed rhodium (Rh) nanoparticles with an average diameter of only 3 nm supported on boron (B) nanosheets. The HER catalytic activity is even comparable to that of commercial platinum catalysts.

November 25, 2020
Researchers prepared an N-doped graphene-decorated NiCo alloy coupled with mesoporous NiCoMoO nano-sheet grown on 3D nickel foam (NiCo@C-NiCoMoO/NF) for water splitting.
Ruthenium-Based Electrocatalysts for Effective Hydrogen Evolution Reaction
April 27, 2021
Researchers summarized four main strategies for improving the hydrogen evolution reaction (HER) performance of Ru-based catalysts.
Low-cost Electrocatalyst for Hydrogen Evolution Reaction (HER)
August 13, 2021
Using first-principles calculations, researchers designed a defect and N-, S-, P-doped penta-graphene (PG) as a two-dimensional (2D) electrocatalyst for HER. Its stability, electronic properties and catalytic performance were investigated.
COP 26
October 12, 2021
In just a few days the nations of the world will once again meet to discuss climate change. The meeting will likely set the stage for action –or lack thereof- that will make or break our collective effort to halt the dumping of greenhouse gases in the atmosphere. This time the meeting will take place in the wake of a rapidly worsening cold war in both fronts (the South China Sea and Eastern Europe) and an acute shortage of gas and coal supplies (and skyrocketing prices) in Asia and Europe just before winter in the Northern Hemisphere.
As so many times before in other areas of human endeavor, France is casting a powerful ray of hope that may sooner rather than later prod the rest of the world, if only to not miss out in the many economic and environmental benefits that the project will eventually generate: President Macron announced that France will build a small modular reactor as well as two mega factories for the production of green hydrogen –by the end of the decade.
This of course is fully aligned in principle with Plan A, which we have espoused for over 10 years. Suffice it to say that if widespread construction of such plants had begun at the time when we first suggested it, net energy importers such as –Hawaii, Puerto Rico, Haiti, the Philippines, the Canary Islands and Iceland, among many others, which happen to be endowed with unlimited seawater, solar and/or geothermal energy, would by now be net exporters of green hydrogen. In other words, they would be receiving, not paying, hard-earned dollars with which to improve their economies.
In sum, it is high time for the rest of the world to emulate France, and we salute President Macron for his bold, innovative decision.
