By optimizing rice husk silica mass and sonication time, SBA-15 was successfully synthesized in a more efficient and environmentally friendly way. The solution of Pluronic P-123 was mixed with the solution containing NaOH and various masses of rice husk s... see more

Hydrogen, as a clean energy carrier, could be produced aided by cyclic oxidation-reduction of oxygen carriers (OCs) in contact with carbonaceous fuel in chemical looping steam methane reforming (CL-SMR) process. In this study, the cerium was incorporated ... see more

In this study, the effect of calcination temperature and Si/Al mole ratio on acidity and physicochemical properties of silica SBA-15 were inves­tigated. Silica SBA-15 samples were calcined at 350, 450 and 550 °C, and then post-synthesis, the Al-grafting m... see more

The synthesis and characterization of  mesoporous silica Santa Barbara Acid-15 (SBA-15) from the ash of corn have been done.  SBA-15 was synthesised using the surfactant template method. SBA-15 from corn leaves  ash has a surface area of 59... see more

SO3H-functionalised mesoporous materials with different pore struc­tures (SBA-15 and SBA-16) were prepared by the post-synthesis surface mod­ification. The materials were thoroughly characterized by X-ray powder dif­fract­ion, nitrogen physisorption, temp... see more

Two VOx/SBA-15 catalysts and three VOx/SiO2-fumed silica, with 5, 10 and 1, 5, 10 %wt. vanadium content respectively, were tested in a stainless steel continuous flow reactor for the partial oxidation of ethanol. The catalysts were tested at 150 – 30... see more

Glycerol steam reforming (GSR) is a promising alternative to obtain renewable hydrogen and help the economics of the biodiesel industry. Nickel-based catalysts are typically used in reforming reactions. However, the choice of the catalyst greatly influenc... see more

The carbon dioxide (CO2) separation can be enhanced by using modified materials like a deep eutectic solvent (DES) modified mesoporous silica SBA-15 in polymeric support i.e polysulfone via mixed matrix membranes (MMMs). The pure SBA-15 and DES are potent... see more

Mesoporous silica (MS) supported by nickel was synthesized from Parangtritis beach sand and assessed for its activity and selectivity as catalysts in hydrocracking waste cooking oil into biofuel. The synthesis of MS was done by the sol-gel method. Ni/MS c... see more
