Abstract
Hydrogen is seen as a very promising, environmentally friendly, and sustainable energy carrier, presenting an appealing substitute for fossil fuels. Photocatalysis, derived hydrogen from water splitting, is often regarded as the most effective method for meeting long-term sustainability goals and satisfying growing energy needs. This article provides a concise overview of the process by which hydrogen is produced by water splitting, using various MOFs and MOF on MOF photocatalysts. MOFs are a very promising category of porous crystalline materials that exhibit a wide range of uses. The extensive investigation of MOFs has resulted in the development of MOF on MOF hybrid materials. This study also elucidates the synthetic approaches that explain the interaction between the host and guest MOFs. Next, the text delves into a comprehensive analysis of the structural variety to showcase how MOF on MOF hybrids facilitates progress in photocatalytic applications. Despite their potential, MOFs still face several constraints that need to be addressed. This work emphasizes the main obstacles in the area of water splitting and suggests the potential use of photocatalysts for this purpose. The extensive surface area of MOF on MOF hybrids also amplifies hydrogen generation during photocatalysis, assisted by effective separation and transmission of electron holes. These photocatalysts generate environmentally friendly hydrogen from water, promoting global progress without causing damage to the environment and perhaps contributing to the development of renewable energy sources. The review concludes by examining possible avenues for future research in the field of photocatalysis for the production of sustainable hydrogen as an energy source.
期刊介绍:
Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
