Optimizing accuracy and efficacy in data-driven materials discovery for the solar production of hydrogen dagger

Iurii Timrov, Matteo Cococcioni

The production of hydrogen fuels, via water splitting, is of practical relevance for meeting global energy needs and mitigating the environmental consequences of fossil-fuel-based transportation. Water photoelectrolysis has been proposed as a viable approa ...

Homogeneous Catalysis for Sustainable Hydrogen Storage in Formic Acid and Alcohols

Paul Joseph Dyson, Gabor Laurenczy, Katerina Stefania Sordakis, Matthias Beller

Hydrogen gas is a storable form of chemical energy that could complement intermittent renewable energy conversion. One of the main disadvantages of hydrogen gas arises from its low density, and therefore, efficient handling and storage methods are key fact ...

Method for producing methanol from carbon dioxide and hydrogen gas in homogeneously catalyzed reactions and in an aqueous medium

Gabor Laurenczy, Katerina Stefania Sordakis

The invention relates to a method for producing methanol from hydrogen and carbon dioxide gas in homogeneously catalyzed reactions, composed of the carbon dioxide hydrogenation reaction to formic acid and the formic acid disproportionation reaction into me ...
