LaNiO3/γ‐Al2O3 catalysts containing 10, 15, 20, and 25 wt % Ni were prepared by a combination of sol gel with propionic acid as solvent and an impregnation method (LNA‐acid) as well as with ethanol as solvent and addition of acetic acid (LNA‐eth). Catalytic activities towards CO2 reforming of CH4 were tested in a fixed‐bed reactor at 700 °C, 750 °C, and 800 °C. LNA‐eth with 20 wt % Ni exhibited the best activities in dry reforming of methane and a good activity and stability, when it was tested at 800 °C during 75 h time‐on‐stream.
In the present study, amid-MCM-41-SO3H nano-composite is fabricated through the electrospinning process, which will a significant step toward air filtration for removal of microrganism from air particularly ICU hospital. The filtration mechanism of the amid-MCM-41-SO3H composite is based on the interaction of nanofiber functionalized group (-SO3H) with surface active groups of lipids and protein of microorganisms such as SARS-CoV-2. For the characterization of the synthesized nano-composite, various instrumentation methods were used. the SEM and TEM showed that the MCM-41- SO3H nanoparticles were uniformly distributed throughout the fiber length. Fourier Transform Infrared (FT-IR) spectroscopy confirms with the synthesized Amid-MCM-41-SO3H filter. X-ray Diffractometry (XRD) pattern indicated that the structure of the MCM-41-SO3H composite was well-preserved after modification. These results suggested that the amid-MCM-41-SO3H composite has higher performance in interaction with similar NPs of virus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
