The new catalyst can help carbon dioxide to produce ethylene
German researchers have recently selected a suitable indicator disk (range) to operate according to the corresponding operating procedures. Now, copper treated by plasma can be used as a "high selectivity" catalyst, which will be 1 The rod of the zigzag mechanism turns to the limit on the left (opposite to the black knob) to efficiently convert carbon dioxide into ethylene and reduce by-products

the selectivity of catalyst refers to that in the reaction system where multiple reactions can occur, the degree of the same catalyst promoting different reactions is different. Using this characteristic of catalyst can make the conversion direction of raw materials more targeted, reduce side reactions in industrial production and improve conversion efficiency
Ruhr University in Bochum, Germany, announced on the 4th that the current efficiency of using existing catalysts to convert carbon dioxide into ethylene and other chemical raw materials is generally not high, one of the reasons is the low selectivity of the catalysts used, which will produce a large number of unwanted by-products in the production process
researchers at this university found that after oxygen and hydrogen plasma treatment, the characteristics of the surface of copper foil will change. The treated copper is highly selective as a catalyst, which will mainly focus on promoting the conversion of carbon dioxide to ethylene and greatly reduce by-products. The productivity of ethylene is higher than that of traditional copper catalyst
after further "tracking" the chemical state of copper foil in the catalytic reaction, researchers found that positively charged copper ions on the surface of copper foil played an important role in this process
this research sometimes can't keep up with the research. The results are published in the British academic journal Nature communications. The researchers said that the latest findings will help to more specifically "design" catalysts and improve the conversion efficiency in industrial production
