A Wet Way to Better Burning? New catalyst uses energy in sunlight to generate hydrogen gas, a carbon-free fuel

A Wet Way to Better Burning? New catalyst uses energy in sunlight to generate hydrogen gas, a carbon-free fuel | Messenger for mother Earth | Scoop.it
Technology is always looking for ways to make it easier to be green. Now, researchers in New York state report creating a new long-lived catalyst that uses the energy in sunlight to generate hydrogen gas, a carbon-free fuel. With further improvements, the advance could lead to systems that use sunlight to split water molecules, generating a fuel that can power cars and trucks without emitting any greenhouse gases.

 

The idea of using sunlight to convert water into a fuel may sound fanciful. But plants do it: They capture photons of sunlight and use that energy to split water molecules into their constituents of hydrogen and oxygen ions. Pairs of hydrogen ions are then knitted together with a pair of electrons (swiped from the oxygen ions) to make hydrogen molecules (H2).

 

Researchers have actually mimicked this same reaction for many years, but the catalysts they use to do so have been either too expensive or too quick to break down. So the search has been on for cheaper, more rugged catalysts.

 

In the current study, reported online today in Science, researchers at the University of Rochester led by chemists Richard Eisenberg and Todd Krauss coated cadmium selenide nanoparticles with short organic chainlike molecules, abbreviated DHLA. This coating of DHLA chains allowed the nanoparticles to dissolve in water. And the individual chains were so short that they allowed the catalyst's nickel ions—also in the solution—to nuzzle close enough to the nanoparticles to grab the electrons and knit H2 molecules together. The Rochester team found that the catalysts were not only fast actors, knitting as many as 7000 H2 molecules every hour, but kept doing so for weeks on end without falling apart—a major advance over other H2-knitting catalysts.

 

Daniel DuBois, a chemist and hydrogen catalyst designer recently retired from the Pacific Northwest National Laboratory in Richland, Washington, calls the new work "a very nice contribution to the area" and says he's particularly impressed with the catalyst's durability. Even so, the new light harvester-catalyst combo isn't quite ready for the real world. For their current experiment, the Rochester researchers didn't actually split water molecules to generate their hydrogen ions. Rather, they added vitamin C, which readily gives up hydrogen, to their solution. So the Rochester group still needs to show that their H2-making compounds will carry out the same reaction using water. If they do, they may give plants a run for their money in green technology.

#Scientist acts out dramatic effect of #climate change

#Scientist acts out dramatic effect of #climate change | Messenger for mother Earth | Scoop.it

Climate science has just made cultural history – yet again. Following on from the sci-fi blockbuster The Day After Tomorrow and the Al Gore documentary movie An Inconvenient Truth, research has got personal and turned into a five-star dramatic soliloquy on the London stage.

Chris Rapley is a professor of climate science at University College London, a former director of the British Antarctic Survey, a former director of the Science Museum in London − and now, unexpectedly, an actor on the stage of the historic Royal Court Theatre.

He is the star and only member of the dramatis personae of 2071, a play named after the date at which, he says, his eldest grandchild will be the age he is now. He has collaborated with playwright Duncan Macmillan, and with Katie Mitchell, a director with a track record of interest in the hard themes of humanity’s future on Earth.

 

The performance, however, could almost be called anti-theatre. There is no conflict, no violence, and there is − beyond the discreet waving of a hand or the re-positioning of a leg − almost no physical action at all. The actor Rapley sits in one place, with only a glass of water as a prop, and embarks on a monologue.

 

Furthermore, it is in one sense an anti-dramatic monologue, sounding in many ways remarkably like a procession of extracts from the abstracts of scientific papers, or the executive summary of any number of publications of the Intergovernmental Panel on Climate Change.

 

There are few concessions to popular language: the diction and choice of terminology is of the kind you tend to hear at science briefings.

Our #oceans are full of dead zones. #Climate change makes them...deader.

Our #oceans are full of dead zones. #Climate change makes them...deader. | Messenger for mother Earth | Scoop.it

Climate change is likely to make existing ocean dead zones...deader, according to a new study by the Smithsonian. Warmer water holds less oxygen, and the researchers found that 94 percent of the world's dead zones are in areas expected to see a temperature rise of 2 degrees Celsius or more by the end of the century. Back in August, Brian Palmer looked at what causes dead zones and how many are out there.

A stretch of the Gulf of Mexico spanning more than 5,000 square miles along the Louisiana coast is nearly devoid of marine life this summer, according to a study released this week. Caused largely by nutrient runoff from farm fertilizer, this oxygen-deprived “dead zone” is approximately the size of Connecticut.

Although slightly smaller than last summer’s edition, the Gulf dead zone is still touted by some as the largest in the United States and costs $82 million annually in diminished tourism and fishing yield. Which makes you wonder…


How many other dead zones are out there?

Probably around 200 in U.S. waters alone. After reviewing the academic literature on “hypoxic zones” in 2012, Robert Diaz, professor emeritus at the Virginia Institute of Marine Science at the College of William and Mary, identified 166 reports of dead zones in the country. Coastal waters contain the vast majority, though some exist in inland waterways. A handful of the 166 dead zones have since bounced back through improved management of sewage and agricultural runoff, but as fertilizer use and factory farming increase, we are creating dead zones faster than nature can recover.
