Question

    Researchers in Australia have discovered an effective new method to capture the atmospheric carbon dioxide that is damaging our planet and transform it into something solid, making it much easier to store.

Carbon capture isn’t new, but previous methods call for the gas to be compressed into liquid and then injected underground. Widespread usage of that technology has been locked by economic and environmental concerns due to possible leaks. Instead, in a study published in Nature Communications, the group details their sustainable and cost-effective plan for transforming CO2 into coal.

This new process involves a liquid metal catalyst( 催化剂 )that is efficient in conducting electricity. CO2 gas is dissolved in a container with some liquid. Once electricity charge is introduced, the CO2 begins to turn into solid pieces of carbon, which can be collected and stored.

What makes this particularly unique is that the entire process can occur at room temperature. Previous experiments have only shown a gas to solid conversion at extremely high temperature, which made it impossible on a large scale. Now, the researchers are hoping that their work will be used to create even further when it comes to carbon storage.

In an interesting side benefit, the solid carbon also works as an electrode( 焊 条 ), which opens up a world of possibilities. “A side benefit of the process is that the carbon can hold electrical charge, becoming a super battery, so it could potentially be used as a part in future vehicles,” explains Dr. Dorna Estrafilzadeh, a researcher. “The process also produces fuel as a by-product, which could also have industrial applications.”

1.What can we know about the previous carbon capture methods?

A.People have to inject liquid to the gas.

B.The previous methods can be done easily.

C.The previous methods are not very popular.

D.People have widely accepted previous methods.

2.What is the special part of the new method?

A.It needs electricity to make the process efficient.

B.It can be done in any kind of container.

C.It doesn’t need extreme temperature.

D.It can produce much solid carbon.

3.What can we infer from the last paragraph?

A.The method will make fossil oil disappear.

B.The method will influence the future industry.

C.The method will make developed countries more powerful.

D.The method will be used to make new vehicles.

4.What is the best title for the passage?

A.How to change carbon into CO2.

B.A new carbon capture technology.

C.A new technology to get useful carbon.

D.Australia makes the world cleaner than before.
