BACKGROUND
4‐Nitrophenol, as a representative hazardous contaminant, may pose potential risks to the environment in the process of production, storage, and use. Catalytic hydrogenation reduction offers a promising route to the removal of 4‐nitrophenol by its transformation into the less toxic and biodegradable 4‐aminophenol. In this work, nickel−cobalt bimetal oxide nanostructures were fabricated...
Catalytic activities of high-silica zeolites of ZSM type and also bi-zeolite catalysts HY-ZSM and LaY-ZSM in the hydrotreatment of a wide fraction of liquefaction products from brown coal (328-698 K boiling range) were determined. All the zeolites were modified by Mo and also Pd, Co and Ni loading. It was shown that ZSM use provides an opportunity to hydrogenate nitrogen compounds selectively in...
