Scientists discover a hidden switch inside silver nanocatalysts
Silver nanocatalysts have been found to switch where they perform their most important reactions depending on whether a solid oxide cell is making electricity or hydrogen. The discovery could enable smarter catalyst designs that boost clean power generation while making green hyd
New catalyst with 75% less platinum promises to reduce the cost of hydrogen fuel cells
New catalyst with 75% less platinum promises to reduce the cost of hydrogen fuel cells
The high cost of platinum is one of the main barriers to the wider adoption of hydrogen fuel cells. Now, researchers at IMDEA Materials Institute have developed a catalyst that delivers the same performance while using 75% less of this expensive metal. The study, published in Ele
Researchers develop a new catalyst to convert CO₂ into ethanol using electricity
Researchers develop a new catalyst to convert CO₂ into ethanol using electricity
A research team led by Professor Hyoyoung Lee of the Department of Chemistry at Sungkyunkwan University has developed a new catalyst that converts carbon dioxide into ethanol with high selectivity. The study, titled "Atomic-scale Cu–Zn synergy directs asymmetric C–C coupling for
Catalyst converts CO₂ into high-value industrial chemical at room temperature with record
Catalyst converts CO₂ into high-value industrial chemical at room temperature with record
A research team has developed a highly efficient catalyst that directly converts carbon dioxide—a major contributor to global warming—into high-value industrial 2-propanol. The research was published online in Applied Catalysis B: Environment and Energy.
Black silicon catalyst turns carbon dioxide into methane with sunlight
Black silicon catalyst turns carbon dioxide into methane with sunlight
Carbon dioxide is often viewed as a major contributor to climate change, but it can also become a valuable raw material. If scientists can efficiently convert carbon dioxide into useful fuels using sunlight, it would provide a sustainable way to store solar energy while reducing
Carbon nanostructure improves fuel-cell catalyst durability while reducing platinum use
Carbon nanostructure improves fuel-cell catalyst durability while reducing platinum use
The explosion of new data centers being proposed and built around the U.S. has increased demand for energy to keep them powered and cooled. The Electric Power Research Institute estimates that data centers could consume up to 9% of U.S. electricity generation annually by 2030, up
New catalyst design selectively suppresses competing hydrogen reaction in ammonia synthesi
New catalyst design selectively suppresses competing hydrogen reaction in ammonia synthesi
A research team led by professor Yousung Jung from the Department of Chemical and Biological Engineering at Seoul National University College of Engineering has developed a new catalyst design principle that suppresses the hydrogen evolution reaction, which interferes with ammoni
New fuel cell breakthrough could help power energy-hungry data centers
New fuel cell breakthrough could help power energy-hungry data centers
A new nanostructured carbon design lets fuel-cell catalysts use tiny amounts of platinum while remaining remarkably stable and efficient. The breakthrough could help hydrogen fuel cells become a more practical way to power data centers, vehicles, and other energy-intensive techno
Chemists set electrons free and break a decades-old chemistry barrier
Chemists set electrons free and break a decades-old chemistry barrier
Chemists have developed a catalyst that breaks a long-standing rule governing which molecules receive electrons during chemical reactions. By releasing electrons directly into solution, the technique could unlock reactions—and potentially useful new molecules—that were previously

UK housebuilders have far too much power. Now a £4.5bn lawsuit could change that for good | Peter Apps
A legal case on behalf of some 700,000 people against the country’s biggest housebuilders could be a catalyst for much-needed industry reformEvery new government – at least for the past decade or so – has come into office with a promise to build more homes. New ministers don a hard hat, take a trip out to a recently completed development and smile indulgently as a bright young couple get given the keys to a smart-looking new-build. Then follows a speech about aspiration.The unspoken tr
