Abstract
Investigators discuss new findings in Machine Learning. According to news reporting out of Shanghai, People's Republic of China, by NewsRx editors, research stated, “The present work successfully proposes a domain knowledge-guided Machine Learning (ML) strategy, which successes the development of a water-tolerant anti-dust catalyst for Low-Temperature (LT) Selective Catalytic Reduction (SCR) of nitrogen oxides (NOx) from catalyst discovery to industrial deployment. The discovered catalyst is able to convert 99 % of NOx at 150 degrees C in the standard waste gas, even in the waste gas containing 7 vol % of water vapors, the efficiency is still retained at 97 %. The superior LT activity and water-tolerance are attributed to abundant surface-active oxygen, Bronsted acid and microcellular structure.” Financial support for this research came from Introduced Jointed Research and Development Institution of Jiangxi. Our news journalists obtained a quote from the research from Shanghai University, “The SCR reaction mainly follows the Eley-Rideal (E-R) pathway driven by Bronsted acid and the Langmuir-Hinshelwood (LH) pathway maintained by abundant reactive oxygen species in moisture waste gases. And then, catalyst is synthesized on a polyphenylene sulfide filter to render the membrane configuration in order to have the anti-dust ability. The final membrane catalyst has the capacity of converting 95 % NOx in the waste gas containing 7 vol% of moisture at 150 degrees C and the dedusting, and denitrification ability.”
