The deployment of hydrogen as an energy carrier is found to be a vital alternative fuel for the future. It expected that water electrolysis, powered by renewable sources, able scale‐up production. However, reaction kinetic oxygen evolution (OER) sluggish process, which predominantly limits efficiency electrolysis. This review recapitulates recent progress and efforts made in design development two selected earth-abundant bimetallic electrocatalysts (NiCo CoFe) alkaline OER. Each bimetal electrocatalyst thoroughly outlined discussed five sub-sections, including (oxy) hydroxides, Layered double hydroxides (LDHs) structures, oxides, composites, alloy nanostructured electrocatalysts, assembled with heteroatoms. Furthermore, brief introduction situ/operando characterization techniques advantages monitoring structure provided. Finally, summary outlining challenges conceivable approaches advance OER performance highlighted discussed.

Catalysts play a critical role in producing most industrial chemicals and are essential to environmental remediation. Under the demands of sustainable development, environment protection, cost-related factors, it has been suggested that catalysts sufficiently separable conveniently recyclable catalysis process. Magnetite (Fe3O4) nanomaterials provide possible way achieve this goal, due their magnetism, chemical stability, low toxicity, economic viability, etc. Therefore, Fe3O4-based materials emerging as an important solid support load heterogeneous immobilize homogeneous catalysts. Moreover, addition magnetic character will not only make recovery much easier but also possibly endow with desirable properties, such magnetothermal conversion, Lewis acid, mimetic enzyme activity, Fenton activity. The following review comprises short survey recent reports catalytic applications materials. It contains seven sections, introduction into theme, remediation, electrocatalysis, organic synthesis, synthesis biodiesel, cancer treatment, conclusions about reported research perspectives for future developments. Elucidation functions mechanisms Fe3O4 nanoparticles (NPs) these may benefit acquisition robust affordable protocols, leading good activity enhanced recoverability.

Pulsed laser ablation in liquid (PLAL) is a physical and top-down approach used to fabricate nanoparticles (NPs). Herein, the research methods current trends PLAL literature are reviewed, including recent uses of for fabricating bimetallic (BNPs) composites. BNPs have gained attention owing their advanced physicochemical properties over monometallic NPs. involves irradiation solid target (usually rod, plate, or thin film) under medium. The collects ejected NPs resulting from processing, which produces colloid that can be various applications, plasmon sensing, energy harvesting, drug delivery. most fabrication techniques, use microorganisms, do not precise NP size control require separation microorganisms produced quicker at producing than bottom-up methods. drawbacks include need find required processing parameters, requires extensive experimentation, complex non-linear relationships between inputs outputs (e.g., size).
