Nanoparticles of Silicon and Water Makes Hydrogen Gas in an Instant

The history of nanotechnology-based solutions for making fuel cells less expensive or more efficient has not really been what you would call a huge success . But a decade ago it seemed the focus on applying nanomaterials to areas such as improved catalysts for fuel cells was driven more by exploiting what the nanomaterials were good at rather than by what fuel cells needed to be more commercially viable. Lately that dynamic has changed and nanotechnology has been finding itself more useful when it comes to cheap ways to isolate hydrogen—the high cost of which has been a key obstacle in reaching the so-called “hydrogen economy” where we can drive around in hydrogen-powered automobiles and power our mobile devices with fuel cells. Three years ago, Angela Belcher at MIT mimicked the process of photosynthesis by developing a man-made virus that could effectively split water mo...
