Sustained solar fuel production in multiple thermochemical cycles using sol-gel derived ferrite nanopowders
(
TechConnect
, 2016 , Conference Paper)
In this paper, the sol-gel synthesis of Mg-doped Niferrite i.e. Ni-Mg-ferrite was attempted by using propylene oxide (PO) as a proton scvanger. Effects of two important synthesis paramaters such as amount of PO added during ...
Energy efficiency of direct contact membrane distillation
(
Elsevier B.V.
, 2018 , Article Review)
Membrane distillation (MD) is a promising technology due to its ability to function using low temperature differences and low-quality heat sources, thus allowing it to operate on solar or waste heat. The flux and energy ...
Computational thermodynamic analysis of solar fuel production via metal oxide based H2O and CO2 splitting thermochemical cycles
(
AIChE
, 2015 , Conference Paper)
In this paper thermodynamic feasibility of the production of solar fuel via SnO2/SnO based thermochemical CO2 splitting redox reactions was investigated. The first step is the thermal dissociation of SnO2 into SnO where ...
Thermochemical conversion of H2O and CO2 into solar fuels via metal oxide based redox reaction
(
AIChE
, 2015 , Conference Paper)
This paper reports the thermodynamic analysis of the production of solar syngas (a mixture of H2 and CO with molar ratio equal to 2: 1) via ZnO/Zn based thermochemical H2O and/or CO2 splitting redox reactions. Solar syngas ...
Thermochemical splitting of CO2 using solution combustion synthesized LaMO3 (where, M = Co, Fe, Mn, Ni, Al, Cr, Sr)
(
Elsevier B.V.
, 2020 , Article)
The effort of this paper was to recognize the inclusion of appropriate dopants that will upgrade the redox reactivity of La-based perovskites. By maintaining the fuel (glycine) to metal nitrate ratio () = 1, the LaMO3 ...
Phase change materials for thermal energy storage applications in greenhouses: A review
(
Elsevier Ltd
, 2022 , Article)
Greenhouses represent one of the largest energy-demanding sectors, requiring energy for indoor environment control for plant growth and crop yield. Thermal energy storage using phase change materials (PCMs) has been ...
Thermal conductivity and latent heat thermal energy storage properties of LDPE/wax as a shape-stabilized composite phase change material
(2014 , Article)
Phase change material (PCM) composites based on low-density polyethylene (LDPE) with paraffin waxes were investigated in this study. The composites were prepared using a meltmixing method with a Brabender-Plastograph. The ...
Effectiveness of Ni incorporation in iron oxide crystal structure towards thermochemical CO2 splitting reaction
(
Elsevier Ltd
, 2017 , Article)
In this study, Ni-doped iron oxide (NixFe3−xO4) materials were synthesized via the 1,2-epoxypropane assisted sol-gel method by varying the molar concentration of Ni from x=0.2 to 1. Sol-gel derived NixFe3−xO4 gels were ...
Synthesis and characterization of nanocrystalline CoFe2O4-zirconia via propylene oxide aided sol-gel method
(
Elsevier Ltd
, 2018 , Article)
In this study, a Co ferrite/ZrO2 ceramic nanomixture, with a uniform distribution of Co ferrite and ZrO2, was synthesized by the propylene-oxide-assisted sol gel method. Cobalt, iron, and zirconium nitrate salts were used ...
Application of cobalt incorporated Iron oxide catalytic nanoparticles for thermochemical conversion of CO2
(
Elsevier B.V.
, 2019 , Article)
This investigation describes the application of the sol-gel synthesized CoxFe3?xO4 (CF) materials towards the solar thermochemical fuel production. The CF materials were derived by sol-gel method (where x was varied in the ...
