Thermochemical hydrogen production from water using reducible oxide materials: a critical reviewMaterials for Renewable and Sustainable Energy - Tập 2 - Trang 1-12 - 2013
Lawrence D’Souza
This review mainly focuses on summarizing the different metal oxide systems utilized for water-splitting reaction using concentrated solar energy. Only two or three cyclic redox processes are considered. Particle size effect on redox reactions and economic aspect of hydrogen production via concentrated solar energy are also briefly discussed. Among various metal oxides system CeO2 system is emergi...... hiện toàn bộ
Synthesis of nanosized MnO2 prepared by the polyol method and its application in high power supercapacitorsMaterials for Renewable and Sustainable Energy - Tập 2 - Trang 1-8 - 2013

Over the last years, the different polymorphs of MnO2 have been intensely studied as alternative compounds to amorphous hydrous RuO2 as supercapacitor electrode materials. In the present work, nanosized birnessite-type MnO2 platelets were synthesized via the polyol method followed by a subsequent ligand removal with NaOH. The resulting compound is easily dispersible in polar solvents, thus allowin...... hiện toàn bộ

AbstractUtilizing artificial intelligent based algorithms in solving engineering problems is widely spread nowadays. Herein, this study provides a comprehensive and insightful analysis of the application of machine learning (ML) models to complex datasets in the field of solar cell power conversion efficiency (PCE). Mainly, perovskite solar cells generate three dat...... hiện toàn bộ
Suppression of magnetism and Seebeck effect in Na0.875CoO2 induced by SbCo dopantsMaterials for Renewable and Sustainable Energy - Tập 9 - Trang 1-8 - 2020
M. H. N. Assadi, Paolo Mele, Marco Fronzi
We examined the electronic property of Sb-doped Na0.785CoO2 using density functional calculations based on GGA+U formalism. We demonstrated that Sb dopants were the most stable when replacing Co ions within the complex Na0.875CoO2 lattice structure. We also showed that the SbCo dopants adopted the + 5 oxidation state introducing two electrons into the host Na0.875CoO2 compound. The newly introduce...... hiện toàn bộ
Correlativity of the nitrogen oxide adsorption mechanism and crystal structure in hollandite-type compoundsMaterials for Renewable and Sustainable Energy - Tập 3 - Trang 1-5 - 2013
Kenjiro Fujimoto, Chihiro Yamakawa, Yuki Yamaguchi, Shigeru Ito
Hollandite-type K1.88Ga1.88Sn6.12O16 and K1.58Ga1.58Ti6.42O16 powders obtained by the solid-state reaction method were examined by DRIFT spectroscopy to evaluate their NO adsorption properties. Two key findings were deduced from the refined structure information and evaluation of NO adsorption on a hollandite surface: first, the presence of oxygen in carrier gas contributed significantly to NO ads...... hiện toàn bộ
Confine sulfur in double-hollow carbon sphere integrated with carbon nanotubes for advanced lithium–sulfur batteriesMaterials for Renewable and Sustainable Energy - Tập 10 Số 1 - 2021
Maru Dessie Walle, You-Nian Liu
AbstractThe lithium–sulfur (Li–S) batteries are promising because of the high energy density, low cost, and natural abundance of sulfur material. Li–S batteries have suffered from severe capacity fading and poor cyclability, resulting in low sulfur utilization. Herein, S-DHCS/CNTs are synthesized by integration of a double-hollow carbon sphere (DHCS) with carbon na...... hiện toàn bộ
