Way Found To Use Chromium Replacing Rare Metal Catalysts

September 13, 2023 | Leave a Comment

University of Basel chemists have succeeded in replacing the rare elements osmium and ruthenium with a significantly cheaper metal. In terms of their properties, the new materials are very similar to those used in the past. Expensive noble metals often play a vital role in illuminating screens or converting solar energy into fuels. We’re familiar […]

Hydrogen Chemical Reaction Storage Idea Developing

March 27, 2019 | 1 Comment

Scientists at the Weizmann Institute of Science, Israel, have developed a chemical storage system based on simple and abundant organic compounds. Hydrogen is a highly attractive, but also highly explosive energy carrier, which requires safe, lightweight and cheap storage as well as for transportation systems. Reported in the journal Angewandte Chemie, the Weizmann liquid hydrogen […]

Produce Hydrogen From Water With Infrared Sunlight

December 5, 2017 | 4 Comments

Kyushu University scientists have synthesized a compound that absorbs near-infrared light to produce hydrogen from water. The compound contains three ruthenium atoms connected by an organic molecule. The absorbed light stimulates electrons to ‘jump’ into orbitals that do not exist in other, similar compounds. This is the first successful use of infrared light to reduce […]

A New Catalyst for Refining Plant Waste

November 14, 2017 | 8 Comments

Osaka University researchers have created a catalyst for refining chemicals in plant waste, allowing a green way to produce valuable raw materials. The research team has discovered how to create valuable chemicals from clean sources. They used biomass, essentially waste from plant materials. Biomass is rich in organic molecules – long chains of carbon atoms […]
