Single-step hydrogen peroxide production could be cleaner, more efficient

26-May-2016 - Bottles of dilute hydrogen peroxide sit on shelves in medicine cabinets across the world, yet synthesizing the chemical at the large scale requires a surprisingly complicated process that is economically unfeasible for all but a few industrial facilities. Chemists and engineers have long been ...

Discovery of a highly efficient catalyst eases way to hydrogen economy

16-Sep-2015 - Hydrogen is usually produced by separating water with electrical power. And although the water supply is essentially limitless, a major roadblock to a future "hydrogen economy" is the need for platinum or other expensive noble metals in the water-splitting devices.Noble metals resist oxidation ...

Cages offer new direction in sustainable catalyst design

27-Jul-2015 - University of Wisconsin-Madison engineers have developed a new approach to structuring the catalysts used in essential reactions in the chemical and energy fields. The advance offers a pathway for industries to wean themselves off of platinum, one of the scarcest metals in the earth's crust.In an ...

Molecular fuel cell catalysts hold promise for efficient energy storage

17-Jul-2015 - In the quest for better, less expensive ways to store and use energy, platinum and other precious metals play an important role. They serve as catalysts to propel the most efficient fuel cells, but they are costly and rare. Now, a metal-free alternative catalyst for fuel cells may be at hand. In ...

Crystal defect shown to be key to making hollow nanotubes

27-Apr-2010 - Scientists have no problem making a menagerie of nanometer-sized objects -- wires, tubes, belts, and even tree-like structures. What they sometimes have been unable to do is explain precisely how those objects form in the vapor and liquid cauldrons in which they are made. Now a team led by ...

New process yields high-energy-density, plant-based transportation fuel

03-Mar-2010 - A team of University of Wisconsin-Madison engineers has developed a highly efficient, environmentally friendly process that selectively converts gamma-valerolactone, a biomass derivative, into the chemical equivalent of jet fuel. The simple process preserves about 95 percent of the energy from ...

University of Chicago establishes new center for chemical innovation

26-Jan-2010 - University of Chicago chemists published an article in the Journal of Chemical Physics three years ago that described an early step in the process for efficiently converting methane into synthesis gas, which is useful for producing liquid fuels and hydrogen. Such developments could be critical if ...

Smaller isn't always better: Catalyst simulations could lower fuel cell cost

21-Sep-2009 - Imagine a car that runs on hydrogen from solar power and produces water instead of carbon emissions. While vehicles like this won't be on the market anytime soon, University of Wisconsin-Madison researchers are making incremental but important strides in the fuel cell technology that could make ...

New process derives 'green gasoline' from plant sugars

22-Sep-2008 - Alternative energy doesn't always mean solar or wind power. In fact, the alternative fuels developed by University of Wisconsin-Madison chemical and biological engineering professor James Dumesic look a lot like the gasoline and diesel fuel used in vehicles today. That's because the new fuels are ...
