A decade of ceria based solar thermochemical H2O/CO2 splitting cycle
Bhosale, Rahul R.; Takalkar, Gorakshnath; Sutar, Parag; Kumar, Anand; AlMomani, Fares; Khraisheh, Majeda... more authors ... less authors ( Elsevier Ltd , 2019 , Article)Since 2006, ceria is used as a redox reactive material for production of H2, CO, and syngas via a two-step solar driven thermochemical H2O/CO2 splitting cycle. Different forms of phase pure ceria were studied over a wide ... -
Application of Li-, Mg-, Ba-, Sr-, Ca-, and Sn-doped ceria for solar-driven thermochemical conversion of carbon dioxide
Takalkar, Gorakshnath; Bhosale, Rahul R.; Rashid, Suliman; AlMomani, Fares; Shakoor, Rana Abdul; Al Ashraf, Abdullah... more authors ... less authors ( Springer , 2020 , Article)The redox reactivity of the Li-, Mg-, Ca-, Sr-, Ba-, and Sn-doped ceria (Ce0.9A0.1O2−δ) toward thermochemical CO2 splitting is investigated. Proposed Ce0.9A0.1O2−δ materials are prepared via co-precipitation of the hydroxide ... -
Effectiveness of Ni incorporation in iron oxide crystal structure towards thermochemical CO2 splitting reaction
Bhosale, Rahul R.; Kumar, Anand; AlMomani, Fares; Ghosh, Ujjal; Sutar, Parag; Takalkar, Gorakshnath; Ashok, Anchu; Alxneit, Ivo... more authors ... less authors ( 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 ... -
Evaluation of redox performance of silver and transition metal-doped ternary ceria oxides for thermochemical splitting of CO2
Takalkar, Gorakshnath; Bhosale, Rahul; AlMomani, Fares ( John Wiley and Sons Ltd , 2019 , Article)Synthesis of Ce0.9M0.05Ag0.05O2‐δ materials (where, M = Ni, Zn, Mn, Fe, Cu, Cr, Co, Zr) via coprecipitation of hydroxide method and examination of these materials toward multiple thermochemical CO2 splitting (CS) cycles ... -
Ni incorporation in MgFe2O4 for improved CO splitting activity during solar fuel production
Takalkar, Gorakshnath; Bhosale, Rahul R.; AlMomani, Fares; Rashid, Suliman; Shakoor, R. A. ( Springer , 2020 , Article)Efficacy of the sol–gel derived Ni-doped Mg-ferrites for an enhanced CO2 splitting activity is investigated. The results allied with the characterization indicate the formation of nominally phase pure Ni-doped Mg-ferrites ... -
Solar thermochemical splitting of H2O and CO2 using nonvolatile metal oxides
