Thermochemical hydrogen production from water using reducible oxide materials: a critical review
Materials 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 supercapacitors
Materials for Renewable and Sustainable Energy - Tập 2 - Trang 1-8 - 2013
E. Goikolea, B. Daffos, P. L. Taberna, P. Simon
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

Selecting an appropriate machine-learning model for perovskite solar cell datasets
Materials for Renewable and Sustainable Energy - - 2023
Mahmoud Salah, Zahraa Ismail, Sameh O. Abdellatif
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 dopants
Materials 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 compounds
Materials 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 batteries
Materials 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
Biodiesel production from transesterified yellow grease by ZSM-5 zeolite-supported BaO catalyst: process optimization by Taguchi’s experimental design approach
Materials for Renewable and Sustainable Energy - Tập 12 - Trang 199-208 - 2023
Adeyinka Sikiru Yusuff, Moses Oluwafemi Onibonoje
Methanolysis of yellow grease (YG) was performed to synthesize its corresponding methyl ester (YGME) using BaO loaded on ZSM-5 (BaO/ZSM-5) as a heterogeneous base catalyst that was prepared via metallic solution hydrolysis method and characterized using N2 adsorption–desorption (BET), surface basicity, XRD, TGA/DTA, SEM, FTIR and Raman techniques.### The Taguchi design approach was utilized to opt...... hiện toàn bộ
Effects of acid concentration, temperature, and time on recycling of post-vehicle-application lithium-ion batteries of varying chemistries
Materials for Renewable and Sustainable Energy - - 2015
Haikun Li, Lindsay Corneal, Charles R. Standridge
Synthesis and application of biomass-derived magnetic biochar catalyst for simultaneous esterification and trans-esterification of waste cooking oil into biodiesel: modeling and optimization
Materials for Renewable and Sustainable Energy - Tập 12 - Trang 147-158 - 2023
Samuel Latebo Majamo, Temesgen Abeto Amibo, Tesfaye Kassaw Bedru
This work created, characterized, and used a magnetic biochar catalyst that is both eco-friendly and very effective. Sugarcane bagasse was selected as primary raw material for catalyst preparation, because it is renewable and ecofriendly biomass. Catalyst created by doping sugarcane bagasse biochar with magnetic material in the form of (FeSO4·7H2O). Thermogravimetric Analysis (TGA) and Fourier Tra...... hiện toàn bộ
