The electrocatalytic reduction of carbon dioxide is a promising approach for storing (excess) renewable electricity as chemical energy in fuels. Here, we review recent advances and challenges in the understanding of electrochemical CO2 reduction. We disc
Today, airplanes pump a lot of climate-warming carbon dioxide into the atmosphere. But someday, carbon dioxide sucked from the atmosphere could be used to power airplanes. A new iron-based catalyst converts carbon dioxide into jet fuel, researchers report online December 22 in Nature Communicati...
In April of this year, the level of carbon dioxide (CO_2) in the atmosphere was 410 parts per million (ppm). The last time CO_2 levels were over 400 ppm was during the mid-Pliocene era 3 to 5 million years ago. Despite moves to renewable energy and attempts to improve efficiency, ...
Centi's team decided to try to use carbon dioxide in its natural form: gas. In a device much like a fuel cell, known as a photoelectrocatalytic reactor, the researchers tested several potential catalysts, ranging from copper to carbon nanotubes. In each case, the process turned CO2into mo...
参考词汇:fossil fuel 化石燃料 carbon dioxide 二氧化碳 Dear fellow students, The foggy weather these days has caused widespread concern about air pollution. Let us take immediate action to fight against air pollution. Li Hua相关知识点: 试题来源: ...
根据上文“Carbon dioxide is released when oil, coal, and other fossil fuels are burned for energy—the energy we use to power our homes, cars, and smartphones. By using less of it, we can limit our own contribution to climate change while also saving money.(当石油、煤炭和其他化石燃料...

If present scientific information is reasonable, the world is likely to experience noticeable global warming by the beginning of the next century if high annual growth rates of fossil fuel energy use continue. Only with optimistic assumptions and low growth rates will carbon-dioxide-induced temperature...
These findings have led scientists to believe that carbon dioxide is a major cause of climate warming. Carbon dioxide is released into the atmosphere when fuel is burned. Oil, coal and wood are all fuels that release the gas. When biological waste breaks down, it also releases carbon dioxide...
Wu said advances in fuel production from carbon dioxide make him more confident that humans will set foot on Mars in his lifetime. “Right now if you want to come back from Mars, you would need to bring twice as much fuel, which is very heavy,” he said. “And in the future, you...
