[ Focus on Chemical Machinery Equipment Network ] In November and December every year, many domestic and foreign media will start to count the news or new results obtained in the past year, and naturally, the relevant inventory in the scientific field is also indispensable.
For example, the recent "Scientific American" monthly magazine counted emerging technologies in 2020.
More importantly, the ten emerging technologies mentioned are all technologies that are considered to have the potential to promote social and economic progress.
Among these ten achievements, two are related to the control and governance of carbon emissions.
They are "photocatalytic conversion of carbon dioxide into common materials" and "low-carbon cement can help combat climate change.
"

The new direction of carbon neutrality uses sunlight and carbon dioxide to produce common materials

In fact, judging from the current situation, one of the core problems of the greenhouse effect is that the carbon emissions generated by human activities exceed the carbon emissions that the earth can purify itself.
But to put it another way, if we can artificially help these "excess" carbon emissions to complete the conversion and achieve carbon neutrality, then the greenhouse effect will naturally be alleviated and even managed.
The technology that can help people complete this process is photocatalytic technology.

　　Simply put, photocatalysis technology is a technology that uses sunlight, a clean energy, to shorten the steps of traditional synthetic chemistry.
And although this technology is young, its history is not short, dating back to 1972.
The semiconductor photocatalytic material is directly related to the photocatalytic technology.

　　At present, there are many photocatalytic materials such as titanium dioxide, zinc oxide, zirconium dioxide and so on.
In addition, there are many practical cases of using photocatalysts to complete air purification.
Titanium dioxide, which is a representative of photocatalytic materials, is a photocatalytic medium used to purify toxic and harmful gases in the air such as formaldehyde.
In recent years, photocatalysts that can reduce carbon and oxygen in carbon dioxide have also been developed.
In theory, as long as they can be used as infrastructure-related platforms or facilities, the collected waste gas will be used to synthesize detergents and textiles in the future.
It is entirely possible.

　　Improve the production process to make common materials more environmentally friendly

　　In foreign media reports, two examples have been put into practice to demonstrate the important impact of the development direction of low-carbon cement on climate change-reducing carbon emissions.
And if we look at this problem from a more intuitive point of view, it is not difficult to find that the essence of this type of emerging technology is actually to improve the original production mode from the perspective of production methods, so as to achieve a more environmentally friendly goal.
From another perspective, not only cement, this view is also applicable to other fields of material production with high carbon emissions.
Even from a certain point of view, the aforementioned use of carbon dioxide to produce ordinary materials is also a material production process that helps combat climate change.

　　But from the perspective of daily life, in addition to developing new processes to make up for the shortcomings of traditional processes in terms of environmental protection, we also need to consider how to improve the original mature processes to maintain productivity while reducing pollution in the production process.
And this is also one of the main directions that need to be considered in materials science.

　　In fact, the editor believes that although the so-called inventory of emerging technologies has certain characteristics, the technology develops very fast every year, and there may be certain omissions in the summary of foreign media.
But the point is that we can see from it, wake up The continuous emergence of technology makes our future more worth looking forward to.
