New Hybrid Catalyst Generates Hydrogen from Water More Efficiently

Arsenij Percov — Sun, 29 Jul 2018 20:06:31 +0000

Ripping water apart into hydrogen and oxygen can form the basis of artificial photosynthetic devices. These devices potentially can power homes and businesses, and car manufacturers will be able to start massive production of hydrogen-powered vehicles. However, catalysts for this type of reaction are either effective but expensive and unstable, or are affordable, stable, and […]

New Sun-Powered Water Splitting Process Discovered

Leigh Hutchens — Thu, 22 Nov 2012 07:29:16 +0000

Researchers have determined that water splitting can produce clean energy hydrogen and use small metal particles exposed to sunlight to perform the splitting. Researchers at Stony Brook University and Brookhaven National Laboratory used gold particles less than one nanometer in size to increase hydrogen production, far exceeding the hydrogen production of other catalysts. Less than […]

Usually, to get hydrogen, the first method that you think of is the electrolysis of water. However, this is not the most efficient way to get the precious energy-carrying gas, and as hydrogen cars will slowly emerge on the market it will need production efficiency, not only the mere fact that it works. So far, […]

New Water-Splitting Catalyst 1000 Times Cheaper Than Platinum May Boost Hydrogen Economy

Ovidiu Sandru — Tue, 05 Jun 2012 15:23:36 +0000

A new electrocatalyst developed at Brookhaven’s National Laboratory can finally make hydrogen fuel cell vehicles a viable reality and can bring cheap electricity for all (hopefully). The researchers discovered how a new form of catalytic nickel-molybdenum-nitride can successfully replace platinum, which sells at $50,000 a kilo these days. “We wanted to design an optimal catalyst […]

New Aluminum Alloy Helps Generate Clean Water and Cheap Electricity

Ovidiu Sandru — Wed, 04 May 2011 16:07:12 +0000

A new aluminum alloy could soon clean out water and at the same time generate electricity for afflicted areas. Purdue University researchers Jerry Woodall and Go Choi have been working on the alloy of aluminum, gallium, indium and tin that could split polluted or salt water into hydrogen and oxygen and then reunite them to generate electricity and pure water.
