The looming fossil energy crisis and serious environment and climate issues urgently call for sustainable energy systems and next-generation energy storage technologies. Instead of a traditional “carbon cycle” based on fossil energy, the “hydrogen cycle” has emerged and may be a promising alternative. With a water splitting device, H2 can be generated from water by electricity or solar energy, and energy transforms between electrical/solar and chemical energy in rechargeable batteries. However, the core issue of water splitting, oxygen evolution reaction (OER) (4OH^– —> 2H₂O + O₂ + 4e^–, in base), is a kinetically sluggish half-reaction, which requires a high overpotential and hinders the development of water splitting.

Recently, a research group from China, led by Prof. Qiang Zhang in Tsinghua University, has developed a novel graphene/metal hydroxide composite with superior oxygen evolution activity. This work is published in the journal Advanced Materials.

Novak Djokovic….helped by Nobel-Prize winning technology. AFP by Jonathan Barrett.

 When world number one Novak Djokovic starts his title defence at Wimbledon, which starts Monday, he’ll be wielding a racquet that relies on Noble-Prize-wining technology.

The Amsterdam-headquartered tennis and ski company Head, which sponsors Djokovic, reinforces its racquets with a wonder material called grapheme.

…CHINESE IMPORTS UP

And possibly also in China’s increased appetite for refined nickel.

Net imports of refined nickel were 17,225 tonnes in May, the highest monthly level since January 2013.

Cumulative net imports of 40,300 tonnes over the first five months of this year were 7.2 percent higher than the year-earlier period, a noteworthy change of trend after more than a year of negative year-on-year comparisons.

Russia has been a major supplier of nickel to the Chinese market for many years so it’s difficult to say to what extent May’s imports from this country of 16,400 tonnes, a near four-year high, were amplified by bets on the ongoing ShFE deliverability questions.

The continued acceleration in imports of ferronickel, a cheaper-priced alternative for China’s stainless steel producers, looks a better indicator of tightening supply in China.

Imports have more than doubled so far this year to 259,000 tonnes and are running at record rates.

However, the single largest component of this year’s ferronickel flow to China, 55,200 tonnes, has come from Indonesia.

Vale SA, the world’s largest nickel producer, is considering selling about 25 percent to 30 percent of its base metals business in an initial public offering.

Work on the transaction continues, although the Rio de Janeiro-based miner will only proceed if nickel and copper prices reach “appropriate” levels, Investor Relations Director Rogerio Nogueira said in Sao Paulo Wednesday.

(Reuters) – Morgan Stanley slashed its nickel price forecasts for the second half of the year on Tuesday as a softer global growth outlook curbs demand from stainless steel producers, making it the third bank this week to downgrade prospects for the metal.

The steel industry is about to go from bad to worse.

China, the world’s biggest consumer of steel, needs less metal. The Chinese housing market, responsible for using the bulk of steel, is bulging with empty properties.
