Turning carbon dioxide into fuel might be possible with this new material
It is increasingly worried that the world will not limit global warming to 1.5 degrees Celsius – the goal set out in the Paris Climate Change Agreement in order to avoid the most dangerous effects.
This has led scientists around the world to try to develop effective ways to remove carbon from the atmosphere.
To address the alarming problem of climate change, a “spongy” scientist, who can turn on the air fuel by removing carbon dioxide has developed.
The achievement is an important step forward in the development of technologies that can generate fuel while reducing the levels of a potent greenhouse gas with solar energy.
When exposed to visible light, a material, an organic crystal structure of nickel converts carbon dioxide (CO2) from carbon monoxide (CO) gas, which can be converted into liquid fuels, solvents and other useful products.
It works by converting carbon dioxide to carbon monoxide, which can be converted into a useful source of energy
The researcher noted that light-activated material was a “critical step” towards making a fuel value while reducing the amount of greenhouse gases in the atmosphere
“We show close to 100 percent selectivity for CO production without detection of competing products such as hydrogen or methane,” said scientist Haimei Zheng at the US Department of Energy’s National Laboratory Lawrence Berkeley (Berkeley Lab)

Interest in the development of catalysts for the reduction of solar energy from carbon dioxide to generate fuel increased with the rapid consumption of fossil fuels in the last century and with the desire of renewable energy sources
“The complete elimination of the competitive evolution of hydrogen during a photocatalytic CO 2 conversion of CO had not been carried out before our work,” said Zheng
The researchers have developed an innovative laser chemical method for the creation of an organometallic material
The nickel precursors were dissolved in triethyleneglycol solution and exposed to the solution of a non-focused infrared laser, which caused a chain reaction in the solution when the metal absorbed light
The resulting reaction formed the metal-organic composites which were then separated from the solution. “When we change the wavelength of the laser, we would have different composites,” said Niu Kaiyang, a materials scientist at Zheng’s lab.
“We have therefore determined that the reactions were activated by light instead of the activation of heat,” said Niu
