Insight Into the Origins of N2O Byproduct on Confinement Structure TiO2/MnSm Catalyst Through Sulfation Pre‐Treatment for Low‐Temperature NH3‐SCR Reaction

EcoEnergy, EarlyView.
Sulfation of TiO2 with tubular architecture assembly nanosheets cooperated with Sm modification endowed the TiO2–SO42−/MnSm catalyst with excellent low‐temperature NH3‐SCR activity, high N2 selectivity, and well H2O‐resistance. It clarifies how the Sm modification and sulfation adjusts the distribution of acid sites and modulates the activation of NH3 ...

The effects of simulated acid rain on growth and biochemistry process in grass (Lolium perenne) [PDF]

, 2009
The effects of simulated acid rain (pH 3 and 4) and control (rain with pH 5.7) on phisiological (germination and grown) and biochemistry process (chlorophyll a and b, carotenoid pigments, peroxidase, catalase) in Lolium perenne were studied. Simulated

Mixed‐Impurity Co‐Poisoning of NH3‐SCR Catalysts: Poisoning Mechanisms, Antagonistic Effects, and Anti‐Inactivation Strategies

EcoEnergy, EarlyView.
This review summarizes the synergistic effects of mixed impurities on ammonia‐selective catalytic reduction (NH3‐SCR) catalysts, including the poisoning mechanism of the catalyst caused by mixed impurities, the antagonistic effects between the impurities, and the research on the anti‐poisoning strategies for the catalyst in recent years.

Effect of simulated acid rain on fluorine mobility and the bacterial community of phosphogypsum

, 2018
Contamination of soil and water with fluorine (F) leached from phosphogypsum (PG) stacks is a global environmental issue. Millions of tons of PG is produced each year as a by-product of fertilizer manufacture, and in China, weathering is exacerbated by ...

Design of a Novel CeW/Fe‐TiO2 Catalyst With High Oxygen Vacancy for Enhancing the Reactivity and SO2 Resistance in Low‐Temperature NH3‐SCR Reaction

EcoEnergy, EarlyView.
Fe3+ was introduced into the TiO2 lattice using the hydrothermal method, and low‐valent cations replaced part of Ti4+ to generate oxygen vacancies within the Fe‐Ov‐Ti unit, resulting in CeW/Fe‐TiO2 catalysts with oxygen‐deficient structures. Compared with CeW/TiO2 catalyst, the increase in oxygen vacancy content significantly improved the catalytic ...

Effects of simulated acid rain on the growth of agricultural crops

Journal of Agricultural Meteorology, 1993
Three species of crops, radish, spinach and bush bean, were exposed to simulated acid rain at pH 5.6 (control) to 2.5 throughout their growing periods. Plants were subjected to acid rain treatment three times a week, for one hour with 10mm of precipitation at a time. All the plants exposed to simulated acid rain falls at pH3.0 or below produced visible

Toward a Paradigm Shift in Low‐Temperature SCR Catalyst Design: Defect Engineering and Data‐Driven Integration

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work systematically reviews the key factors influencing the performance of low‐temperature NH3‐SCR. The mechanism and challenges of defect engineering strategies, such as oxygen vacancies, heteroatom doping, crystal facet exposure, and surface reconstruction, in controlling both activity and selectivity were analyzed.

The Effect of Acid Rain on Strength and Corrosion Performance of Slurry Infiltrated Fiber Concrete

Zanco Journal of Pure and Applied Sciences, 2019
The acid rain has a serious effect on the durability of reinforced concrete, especially when the pH value of the acid rain decreased lower than a certain limit. The acid rain can cause erosion of concrete stone and corrosion of steel reinforcement.
