CO2 Reforming of CH4 over Ni/SBA-15: Influence of Ni Loading on the Metalsupport Interaction and Catalytic Activity [PDF]

open access: yes, 2017
The influence of Ni loading on the properties of Ni/SBA-15 and CO2 reforming of CH4 were studied. XRD, BET and TGA results indicated that the increasing Ni loading (3–10 wt%) decreased the crystallinity, surface area and physically adsorbed water content

Functionalized Nanoporous Silica by Mono and Dendrimeramine in Methylene Blue Removal from Wastewater [PDF]

open access: yesآب و فاضلاب, 2016
Many organic dyes such as Methylene Blue are toxic, carcinogenic, and non-biodegradable due to their aromatic complex structure and high solubility in water. It is, therefore, essential to remove them from effluents discharged into the environment.
