(Phys.org) —As the world's dependence on fossil fuels causes ever-increasing problems, researchers are investigating solar fuels as an alternative energy source. To make solar fuels, sunlight is converted into hydrogen ...
(Phys.org) -- By converting sunlight into chemical energy, artificial photosynthesis systems could potentially produce renewable, nonpolluting fuels and chemicals for a wide variety of uses. But developing an efficient solar-to-fuel ...
(PhysOrg.com) -- There are many ways to generate hydrogen, such as water electrolysis and steam reforming of gas, but the hydrogen produced by these methods tends to be combined with other byproduct and residual gases. For ...
The hydrocarbon methane is highly abundant on Earth, yet its release is now known to contribute to surges in temperature and climate change. In recent years, researchers have been trying to devise reliable methods to directly ...
By mimicking photosynthesis, the light-driven process that plants use to produce sugars, MIT researchers have designed a new type of photocatalyst that can absorb light and use it to drive a variety of chemical reactions.
