New type of alkyne hydrogenation catalyst was successfully developed
On January 8th, Professor Audrey Moore from McGill University in Canada, the core conjugate of manganese oxide, iron oxide core-shell nanoparticles, and mild conditions Hydrogenation of olefins and alkynes in aqueous ethanol is achieved. It is understood that this type of catalyst is very durable against oxidants such as oxygen and water, can be recovered magnetically, and is selective for very few active double bonds. Related research results have been published in the RSC journal "Chemical Newsletter."
The aluminum air battery application can widely use in the field like civil, industrial and military, mainly use for emergency energy for house/ hotel / hospital/ fire control/ public area emergency light, power bank for phone and computer, barn lantern, standby power of building, communication base station, emergency rescue,refuge park, mine, camping, field training, field power supply, charging, maintenance, lighting requirements. The aluminum-air battery uses high-purity aluminum (containing 99.99% aluminum) as the negative electrode, oxygen as the positive electrode, and potassium hydroxide (KOH) or sodium hydroxide (NaOH) aqueous solution as the electrolyte . Aluminum ingests oxygen in the air and produces a chemical reaction when the battery is discharged. Aluminum and oxygen are converted into aluminum oxide.
