MOF-Derived Porous Ternary Nickel Iron Nitride Nanocube as a Functional Catalyst toward Water Splitting Hydrogen Evolution for Solar to Chemical Energy Conversion

Abstract: Prussian blue analogue (PBA)-derived porous ternary metallic nitride (Ni3FeN) has been successfully prepared through a simple two-step oxidation–rapid nitridation process and used for the photocatalytic hydrogen evolution reaction. The porous structure of the Ni3FeN nanocube contributes to the adsorption of the Eosin-Y photosensitizer, while also ensuring sufficient exposed active sites. This aids in improved reaction kinetics of the photocatalytic hydrogen evolution reaction. Moreover, the superior conductivi… Show more

“…A smaller arc radius means that the catalysts resistance is lower and thus possesses better charge transfer properties. 42,43 This shows that the Ru/ TiO 2 composites, and especially fcc Ru/TiO 2 , have a strongly reduced charge transfer resistance with the solution compared to pristine TiO 2 , which leads to an enhanced photoactivity.…”

“…74 Recent works have demonstrated that the combination of TMN materials with photosensitizers can also exhibit excellent photocatalytic performance. 75,76 Unlike traditional semiconductor materials, these TMN materials developed for dye-sensitized photocatalytic systems are usually conductive materials and cannot be considered as photocatalysts. They primarily serve the purpose of electron transfer and providing active sites for chemical reactions.…”

“…5h), often possess advantages such as a higher density of active sites and shorter carrier transfer distances. 66,76 Taking a Prussian blue-derived iron nitride nanocube catalyst as an example, this iron nitride (Fe 2 N) nanocube exhibits higher photocatalytic dye-sensitized hydrogen evolution activity than its nanoparticle counterpart derived from the same Prussian blue precursor. 108 Therefore, by utilizing specialized synthesis methods to prepare TMNs with unique morphologies and designing TMN-based photocatalysts based on them, it becomes possible to achieve improved photocatalytic efficiency.…”

“…With the progress of nanotechnology, metal–organic frameworks (MOFs) as new porous nanomaterials have aroused considerable research interest. Due to their peroxidase-like activity, low toxicity, high porosity, and large specific surface area, MOFs have been widely used in catalysis, , sensing, , drug delivery, , gas storage, , and optical devices. , Recently, the potential of MOFs was further exploited for extensive sensing and antibacterial treatment fields by loading fluorescent probes and biological enzymes. However, these studies were limited to single function applications such as monitoring or sterilization, the construction of MOF-based multifunctional NFs for diabetic wound healing management is an urgent need.…”
