Investigations on conversion of CO2 to methanol over ordered mesoporous material supported NiGaCo catalyst (NiGaCo/MSO catalyst)

This study reported preparation, characterizations and application of NiGaCo/MSO catalyst in conversion of CO2 to methanol under mild conditions. The catalyst was characterized by many techniques such as XRD, SEM, TEM, BET and XPS for confirming its structure and element characteristics of active site. The conversion was investigated on effects of many factors including temperature, pressure, feestock compostion to the process performance. The results showed that the NiGaCo/MSO catalyst was high activity and selectivity in the methanol synthesis where the application could be established at mild pressure (15 bar) and temperature (240oC) for a good methanol selectivity (87.8%) and overall yield (32.6%).

Rubidium ion Capture with a phosphotungstic acid-functionalized finger-citron-residue-based carbon

A new type of adsorbent PTA@FMC, which was designed and fabricated using the ordered mesoporous material FMC as the support, shows a promising potential for the practical capture of rubidium ion.

Co/SBA-15 modified with TMB in the degradation of phenol

Mesoporous materials like SBA-15 offer excellent properties such as catalyst support adsorbent due to its textural characteristics and their surface chemistry. The main objective of this study was to support cobalt (20 % w) in the type ordered mesoporous material SBA-15 and expand the pore size with the introduction of a "blowing agent", such as 1,3,5-trimethylbenzene (TMB), to be evaluated in the degradation of phenol. By its physicochemical characterization, it was confirmed that this is an ordered mesoporous material with two-dimensional hexagonal structure (p6mm) with high specific area, narrow pore distribution and typical morphology of this material. The pore size of SBA-15 has been extended to 19 nm by the addition of cosolvent organic molecules (TMB) and the particle size of cobalt decreased from 18.8 nm in SBA-15 to 6.4 nm on average by supporting it in SBA-15 modified with TMB; this property seems to confer the material be more selective in the conversion of CO2, which is the reason why it has greater activity for the degradation of phenol.

Natural kaolin derived stable SBA-15 as a support for Fe/BiOCl: a novel and efficient Fenton-like catalyst for the degradation of 2-nitrophenol

The ordered mesoporous material SBA-15 (FCSBA-15) with an enhanced hydrothermal stability was successfully synthesized from natural kaolin in the presence of a fluorocarbon surfactant.
