How porous periodicity of mesoporous materials like TiO2-SBA-15-10 encourages photocatalytic degradation of rhodamine B: a comparative study with aperiodic TiO2-SiO2-aerogel-10

Direction of theoretical and experimental investigation into the mechanism of n-HA/Si-PA-SC@Ag as a bio-based heterogeneous catalyst in the reduction reactions

“…Then 300 mg n-HA/Si-PA-SC@Ag and a solution of NaBH 4 (10 mmol in 2 mL H 2 O) were added to them and both were stirred until they became colorless (pH ~ 10. [5][6][7][8][9][10][11]. Upon completion of the reduction, the reaction process was followed by UV-Vis.…”

“…In this regard, catalytic processes are considered as a green method because they achieve specific chemical transformations in the shortest time in the presence of a small amount of catalyst and reduce production costs as well as environmental risks 1,2 that natural and heterogeneous catalysts can be the best candidates 3 . In fact, nanomaterial-based catalysts have been extensively applied to accelerate processes while maintaining the principles of green chemistry 4,5 . In general, a heterogeneous catalyst with the unique characteristics of activity, stability and high selectivity is the developer of novel generation of solid-catalysts in the production of good chemicals for refinery operations and the environment 6 .…”

Electric Field as a Useful Tool to Improve the Poor Adsorption Affinity of Pollutants on Carbonaceous Aerogel Pellets

“…In recent years, aerogels have attracted attention of material scientists. Aerogels are materials that have low density, high surface area, and large pore volumes [5]. Moreover, its large surface area and pore volume play an important role as capacitive electrodes for adsorption of ions from the electrolytic solution.…”
