University of Oxford researchers have found a new class of materials called halide double perovskites may have just the right properties to split water. In a process called photocatalytic water splitting, sunlight separates water into hydrogen and oxygen. The hydrogen and oxygen can then be recombined in a fuel cell to release energy. According to […]

According to Rice materials scientist Rouzbeh Shahsavari, who developed it with graduate student Sung Hoon Hwang the material is cementless and environmentally friendly. The fly ash binder does […]

University of Toronto engineers have designed a most efficient and stable process for recycling carbon dioxide into a key chemical building block for plastics – all powered using renewable electricity. The new technology takes a substantial step towards enabling manufacturers to create plastics out of two key ingredients: sunshine and pollution. Today, non-renewable fossil fuels […]

University of Nebraska researchers are offering new guidelines that could steer the design of less costly, more efficient catalysts geared toward revving up the production of hydrogen as a renewable fuel. Based on an equation the team developed they discovered several atom-framework combinations that approximate the performance of precious-metal catalysts – platinum, gold, iridium – […]

Brown University researchers have developed a new theory to explain why stretching or compressing metal catalysts can make them perform better. The theory, described in the journal Nature Catalysis, could open new design possibilities for new catalysts with new capabilities. Catalysts are substances that speed up chemical reactions. The vast majority of industrial catalysis involves […]
