Researchers at Stockholm University have found a new critical point in supercooled water at around -63 °C and 1000 atmosphere. This discovery explains the unusual properties of water, such as its density and viscosity responding to pressure and temperature changes in ways that are opposite to other liquids.
A new study has found that the ocean's ability to absorb CO2 is stronger than previously assumed, with air bubbles playing a key role in this process. The research suggests that the ocean absorbed around 0.3-0.4 petagrams more carbon per year, about 15% more than previous estimates.
A study by researchers from Dalian Institute of Chemical Physics reveals the interface confinement effect on open space in In2O3-TiO2 catalyst, leading to enhanced activity and stability. The formed InOx nanolayers show distinct chemistry and can be confined on various oxide surfaces.
Researchers develop a new migration strategy that enhances CO2 reduction to CO via reverse water-gas shift reaction in Ru/(TiOx)MnO catalysts. The approach boosts catalytic activity by 3.3 times and improves H-spillover for efficient hydrogen transportation.
The study found that Cu-ZnO-Al2O3 catalysts have two active sites: CuCu(100) hydroxylated ZnO interface for water gas shift reactions and Cu(611) Zn alloy for CO hydrogenation to methanol. The researchers used in situ characterization technology and theoretical calculation to determine the active site structures.
Researchers have developed a new catalyst for the low-temperature hydrogenation of CO2 to methanol with high activity and selectivity. The sulfur vacancy-rich few-layered MoS2 catalyst achieves 94.3% methanol selectivity at 180°C, outperforming commercial catalysts.
Researchers from Waseda University and ENEOS Corporation discover a novel indium oxide modified with copper that exhibits a record-breaking CO2 conversion rate of 10 mmol/h g at relatively modest temperatures. This breakthrough could significantly contribute to reducing carbon footprint and driving towards a more sustainable future.
A recent study found that the autocatalysis of water enhances the formation of COOH intermediate through proton transfer, accelerating CO generation while hindering methanol synthesis. The research also revealed that high initial partial pressure of water inhibits CO2 conversion due to excessive OH* coverage.
An international team has developed a new catalyst for producing high-purity hydrogen gas at low temperatures and pressures. This breakthrough could improve the efficiency of fuel cells that run on hydrogen fuel and reduce costs.
Scientists have developed a new low-temperature catalyst that produces high-purity hydrogen gas while using up carbon monoxide, improving the performance of fuel cells. The catalyst operates at low temperature and pressure, making it less expensive and easier to use.
