The new "metal glass" catalyst can efficiently treat sewage Edith Cowan University in Australia recently said that scientists at the university used nanotechnology to create a new type of "metal glass" (also known as amorphous alloy) catalyst, which can treat sewage
environmentally friendly and efficiently.
Zhang Laichang, an associate professor at the School of Engineering at Edith Cowen University, who led the study, pointed out that compared with the current common way of using iron salts, iron ions, etc.
as catalysts to treat industrial wastewater, "the use of metal glass catalysts will not cause secondary pollution in the first place, and its catalytic efficiency is high and can be reused more than 20 times
.
" Since metallic glass can already be produced on a large scale, the market price is low and the operating and maintenance costs are low"
.
Zhang Laichang's team used nanotechnology to change the atomic structure of iron to make a new type of iron-based metal glass strip
with an atomic packing structure of "long-range disorder and short-range order".
Under laboratory conditions, the new material adsorbs substances such as impurities in dyes and heavy metal waste liquids, purifying
wastewater in minutes.
The research results were recently published in the
scientific journal Advanced Functional Materials in the United States.
