In Situ Electrochemical Oxidation Tuning of Transition

The development of catalysts with earth-abundant elements for efficient oxygen evolution reactions is of paramount significance for clean and sustainable energy storage and conversion devices. Our group demonstrated recently that the electrochemical tuning of catalysts via lithium insertion and extraction has emerged as a powerful approach to improve catalytic activity. Here we report a novel

Renewable electricity storage using electrolysis

Electrolysis converts electrical energy into chemical energy by storing electrons in the form of stable chemical bonds. The chemical energy can be used as a fuel or converted back to electricity when needed. Water electrolysis to hydrogen and oxygen is a well-established technology, whereas fundamental advances in CO2 electrolysis are still needed to enable short-term and seasonal energy

Effect of Electrolysis Conditions on the Composition and

2021/3/11These metals, as elements of transition groups, have the strongest interatomic bond owing to vacancies in the inner electron shells. This factor is responsible for the high refractoriness, strength, and hardness of these materials and their high resistance to the action of loads at high temperatures.

Hydrogen: Enabling the transition to green chemistry

These two elements can be separated with electricity by electrolysis to produce H 2, but the process is so energy intensive that until now hydrogen has mostly been extracted from natural gas. That also requires a lot of energy and generates the greenhouse gas CO 2 as a byproduct.
