This work reports the application of Mn-doped Co 3 O 4 oxides in electrocatalytic oxygen evolution reaction (OER) different pH electrolytes. Higher : Mn molar ratio presented lower electron transfer resistance and most promising activity.
Abstract This review article describes the most recent studies carried out in catalytic conversion of 5‐hydroxymethylfurfural (5‐HMF) 2,5‐dimethylfurane (2,5‐DMF). In this way, novel materials are presented and their main results during 2,5‐DMF production through hydrogen transfer (CHT) by hydrogenation hydrogenolysis reactions hydrodeoxygenation (HDO) reaction as commonly routes employed. Additionally, optimized conditions applying for each catalyst discussed. Some future perspectives on...
Post-combustion carbon dioxide (CO2) capture/separation is considered one of the main ways to minimize impact global warming caused by this greenhouse gas. This work used eight mono- and dicarboxylate-based ionic liquids (ILs) impregnate metal-organic framework (MOF) ZIF-8. anionic effect was studied for these mostly unreported IL@MOF composites determine its on gas sorption selectivity performance. Characterization results confirmed IL impregnation into structure ZIF-8, along with...
Energy and the environment will always play key roles in society. The climate emergency cannot be ruled out to enable transition for a clean energy future. Currently, non-renewable resources are declining, therefore is important continuously explore renewable resources. Biomass resource that can applied reduce changes accomplhish emission policies. Cellulose most abundant type of biomass worldwide, which transformed into biofuels potential building block platform molecules (e.g furfural)...
Palladium(II) oxide supported over Co3O4 was studied as an electrocatalyst for oxygen evolution reaction (OER) in acid, neutral, and alkaline solutions. has limited stability to solution, while PdO goes from slightly acidic pH. The combination of both materials envisioned improve the OER activity a wide range electrolyte PdO@Co3O4 were synthesized by solvothermal method using urea. deposited small spheres on surface (8.9 wt % Pd) caused changes spinel structure compared pure oxide, such...
The name perovskite is related to ceramic compounds that contain metallic and non-metallic elements, well-defined crystal structure its most abundant molecular formula ABO 3 , where usually A refers an alkali metal, alkaline earth metal or a lanthanide B transition metal.These solids can exhibit interesting properties such as high catalytic activity, superconductivity, ferromagnetism, appreciable thermal stability conductivity.The intrinsic characteristics of each are dependent on their well...
