Recently, according to foreign media reports, a new study published by the Korean Academy of Science and Technology in Science showed that they have developed a durable and economical catalyst that can recover greenhouse gases into fuel, hydrogen and other chemicals. The composition of the substance.
The researchers said that the catalyst is made of cheap and abundant nickel, magnesium and molybdenum. It is a nickel-molybdenum nanoparticle formed in the reducing environment of single crystal magnesium oxide, which can initiate and accelerate the conversion of carbon dioxide and methane into hydrogen The reaction rate, and the validity period can be as long as more than a month.
This conversion is called "dry reforming" and can convert harmful gases such as carbon dioxide into chemicals that can be used in fuels, plastics and even pharmaceuticals. Previously, this process required rare metals such as platinum and rhodium to generate this chemical reaction.
The researchers named this catalyst as a single crystal edge nanocatalyst (NOSCE), which can seal its own high-energy active site during the reaction and permanently fix the position of the nanoparticles, which means that the catalyst will not produce carbon yet. build up.
The researchers expressed the belief that the NOSCE mechanism will significantly improve other inefficient catalytic reactions and further reduce greenhouse gas emissions, which may be a revolutionary result of reversing the trend of global warming.
