SnCl4/nano-sawdust was prepared as a carbohydrate-based catalyst containing of tin bearing cellulose units. The catalyst was characterized by X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM) and energy dispersive X-ray spectroscopy (EDS). The catalyst was applied successfully as a readily available, inexpensive, biodeg...

TiO2 photo catalyst was prepared in presence of nano SiO2 and Hydroxy Propyl Cellulose (HPC) by sol gel method with Titanium Tetra IsoproPoxide (TTIP) as titanium precursor. Additional effect of HPC in preparation of nano catalyst, and photo catalyst properties measured and characterized by FT-IR, FT-Raman and SEM. The catalyst size and structural properties of the film were determined by .-Ray...

Nano-TiO2 is widely applied in the automobile exhaust hose reels as a catalyst to reduce oxynitride emissions, including nitric oxide (NO). In the biomedicine field, NO plays an important role in vasodilation and edema formation in human bodies. However, the deswelling activity of nano-TiO2 has not been reported. Here, we demonstrated that nano-TiO2 can significantly degrade the production of N...

For the first time a novel oxygen reduction catalyst with a 3D platinized graphene/nano-ceramic sandwiched architecture is successfully prepared by an unusual method. Herein the specific gravity of graphene nanosheets (GNS) is tailored by platinizing graphene in advance to shorten the difference in the specific gravity between carbon and SiC materials, and then nano-SiC is well intercalated int...

This paper presents a two-dimensional computational model of micro-structured cathodic electrodes featuring nano-porous gas diffusion media that increase the surface to volume ratio of the deposited catalyst layer. A key objective of the modeling effort is to elucidate the Knudsen diffusion within the nano-porous electrode. In addition, the model is non-isothermal and resolves the natural conve...

Majority of materials employed for food packaging are non-biodegradable materials which do not meet increasing demands in society for sustainability and environmental safety. Thus, numerous biopolymers have been exploited to develop biodegradable food packaging materials. Nonetheless, the usage of biopolymers has been limited due to the poor mechanical and barrier properties. These properties c...

Magnetic particles have been studied with much interest with reference to many engineering applications. Much effort has been devoted to the preparation of nano-sized magnetite particles with well-controlled size and shape. Magnetic bacteria synthesize uniform and nano-sized magnetite particles enveloped by organic lipid membranes. This review discusses recent advances in bacterial magnetite pa...

Nano-cellulose with high amount of free OH groups could be used as supporting agents for boron trifluoride (BF3). Nano-BF3/cellulose is a solid acid and a biodegradable catalyst which was prepared via reaction of nano-cellulose and BF3. The structure of this catalyst was studied by FT-IR, FESEM, TEM, XRD, EDS, TGA, XRF and BET. In this research, the synthesis of...

Microwave assisted reactions have gained considerable attention, due to versatility and reduction ofsolvent and reaction time. The reaction of a nano-coconut shell and boron tri-fluoride in diethylether solvent resulted in preparation of nano-coconut shell-BF3 as a catalyst. The nano-coconutshell-BF3 catalyst has been characterized by fourier transform infrared spectroscopy (F...

The supported palladium nanoparticles catalyst with uniform-sized Pd particles distribution and without nitrogen or chlorine atoms present in catalyst was prepared by calcination of the supported [Pd(lysine·HCl)(Cl)2] complex as precursor and characterized by TEM. Moreover the supported [Pd(lysine·HCl)(Cl)2] complex was from cation exchanging [Pd(lysine·HCl)(Cl)2] complex with inorganic support...
