“…Under the best experimental conditions, a continuous stream of 20 kg h −1 was calcined to 95%, with an overall thermal efficiency of 17% (accounting only for reaction heat) or 29% (reaction plus sensible heat contributions). Ouaida et al (1985) investigated reduction of ilmenite (FeTiO 3 ) in a directly irradiated ordinary (Type A) FB reactor with the aim of selectively reducing iron oxide. Titania-rich products may be further chemically treated to obtain TiO 2 .…”

Thermal and thermochemical processes can be efficiently developed and carried out in fluidized beds, due to the unique properties of fluidized suspensions of solid particles and to the inherent flexibility of fluidized bed design and operation. Coupling fluidization with concentrated solar power is a stimulating cross-disciplinary field of investigation, with the related issues and opportunities to explore. In this review article the current and perspective applications of fluidized beds to collection, storage and exploitation of solar radiation are surveyed. Novel and “creative” designs of fluidized bed solar receivers/reactors are reported and critically discussed. The vast field of applications of solar-driven fluidized bed processes, from energy conversion with thermal energy storage, to solids looping for thermochemical energy storage, production of fuels, chemicals and materials, is explored with an eye at past and current developments and an outlook of future perspectives.

“…Many Fe-based materials highly influence of the electrochemical performance, because the direct excitation of the Fe-O in these with containing materials induces the electron transfer from O 2− to Fe 3+ to form Fe 2+ , which is responsible for the catalytic CO 2 reduction [22]. At different electrochemical system and condition Fe-based materials play very well like, Fe-containing MoF and TiO 3 showed photocatalytic for CO 2 reduction under visible light irradiation [22][23][24]. A flower like FeTiO 3 pronounced and stable pesudocapacitance has been found [25].…”

The effect of electrochemical reduction of carbon dioxide (CO 2 ) by changing the structure and morphology of FeTiO 3 nanoparticle prepared through sol-gel and hydrothermal methods is explained in this study. FeTiO 3 nanoparticles were used as a cathode where as a stainless steel plate and CO 2 − saturated NaHCO 3 were used as an anode and an electrolyte, respectively. The cyclic voltammetry and linear sweep voltammetry analysis were carried out comprehensively on FeTiO 3 -SG-and FeTiO 3 -HT-coated electrodes to decouple the electrochemical reduction processes of CO 2 in aqueous solution. The charge transfer resistance and the product gases were studied using electrochemical impedance spectroscopy and gas chromatography, respectively. The observed results were analyzed in light of structure/morphology, particle size, and surface area of FeTiO 3 nanoparticles and their influence on the effective cathodic behavior in CO 2 to CO reduction.
