Metal-ion catalysts and hydrogen peroxide could green up plastics production
Researchers at the University of Illinois are contributing to the development of more environmentally friendly catalysts for the production of plastic and resin precursors that are often derived from fossil fuels. The key to their technique comes from recognizing the unique physical and chemical properties of certain metals and how they react with hydrogen peroxide.

Researchers develop extremely sensitive hydrogen sensor
Hydrogen is a highly promising energy carrier. But it can also be dangerous, as it is combustible and difficult to detect. Using hydrogen safely requires sensors that can detect even the smallest of leaks. Researchers from Delft University of Technology (TU Delft, The Netherlands), KU Leuven (Belgium) and the Rutherford Appleton Laboratory (UK) have discovered that the metal hafnium is perfect for the job.

Nature demonstrates how bacteria degrade lignin and provides better understanding to make biofuels
The production of biofuels from plant biomass is a highly promising source of energy, but researchers are trying to find microbes that readily degrade recalcitrant lignin found in plant biomass. Recent comprehensive genomic and metabolomic analysis of a known lignin-degrading bacterium provides insight into how this degradation is accomplished.

Ultrathin black phosphorus for solar-driven hydrogen economy
Hydrogen as a fuel source, rather than hydrocarbons like oil and coal, offers many benefits. Burning hydrogen produces harmless water with the potential to eliminate carbon dioxide emissions and their environmental burden. In pursuit of technologies that could lead to a breakthrough in achieving a hydrogen economy, a key issue is making hydrogen cheaply. Using catalysts to split water is the ideal way to generate hydrogen, but doing so usually requires an energy input from other chemicals, electricity, or a portion of sunlight which has high enough energy.
