Core-shell and Immobilized Nanoscale Ferrites for H2 Generation From Thermochemical Water-splitting

Amar V., Puszynski J., Shende R., South Dakota School of Mines and Technology, US

In this study, water was used as energy carrier for H2 generation via thermochemical water-splitting process using core-shell and immobilized nanoscale ferrite materials. Core-shell ferrite nanoparticles were synthesized using pluronic P123 templating assisted sol-gel method. [...]

Synthesis of Nano-Sized Ferrite Materials for H2 Generation from High Temperature Water-Splitting Reaction

Bhosale R., Shende R., Puszynski J., South Dakota School of Mines & Technology, US

As the current research trends in H2 generation using thermochemical water-splitting reaction are focused towards lowering the H2 generation temperatures, it is believed that the nano-sized ferrite materials with porous morphology will significantly reduce the [...]

Sol-gel Synthesis of Ferrite Foam Materials for H2 Generation from Water-Splitting Reaction

Bhosale R., Shende R., Puszynski J., South Dakota School of Mines & Technology, US

Ferrites in the form of spinel, doped spinel, and wustite are used for H2 generation from thermochemical water-splitting reaction. Although these ferrites have been synthesized by solid-state mixing, self-propagation high temperature synthesis and aerosol-spray pyrolysis [...]

Mesoporous TiO2 thin-film for Dye-Sensitized Solar Cell (DSSC) Applicationv

Vats A., Shende R., Swiatkiewicz J., Puszynski J., South Dakota School of Mines & Technology, US

The DSSC is a low-cost device as compared with the conventional ‘p-n’ junction devices. This device utilizes about 5 m thick film of TiO2 nanocrystals to form a ‘bulk’ junction with a large surface area [...]

Formation of Pyrophoric _-Fe Nanoparticles from Fe(II)-Oxalate

Shende R., Vats A., Doorenbos Z., Kapoor D., Puszynski J., South Dakota School of Mines & Technology, US

The formation of pyrophoric Fe-nanoparticles from Fe(II)-oxalate decomposition under H2 atmosphere was the main objective of this research. Iron oxalate was synthesized by controlled nucleation process involving addition of oxalic acid in the FeCl2.2H2O solution [...]
