Novel low-temperature adsorption material Ni0.85Se for efficient removal of elemental mercury from coal-fired flue gas

Mercury pollution poses a serious hazard to the ecological environment and human well-being. The issue of mercury emissions has always been a hot topic of concern. In this work, spherical Ni 0.85 Se material was successfully prepared and applied for the first time in the mercury removal of coal-fired flue gas. After a series of experiments and characterization studies, it was found that Ni 0.85 Se has excellent mercury removal performance in low-temperature environments below 120°C, especially with almost 100% mercury removal efficiency below 60°C. It effectively removes mercury from the coal-fired flue gas at power stations and can be adopted as an effective adsorption material for mercury removal in other industries with coal combustion.
