electrochemical transformation of Ni to NiOOH as an effective electrode for water oxidation reaction.

The poor kinetic background with the four-electron transfer of the oxygen evolution reaction (OER) was eradicated using a nickel-based catalyst, which was identified as an alternative to noble-metal catalysts. Here, we report the simple formation of an earth-abundant nickel oxyhydroxide (NiOOH) electrocatalyst for efficient OER in an alkaline medium. Electroless material preparation, namely, the direct modification of a gas diffusion layer (GDL) with a nickel salt, was studied, and the layered oxyhydroxide phase was found to influence the rate of the OER.

Heterostructured Au NPs/CdS/LaBTC MOFs Photoanode for Efficient Photoelectrochemical Water Splitting: Stability Enhancement via CdSe QDs to 2D-CdS Nanosheets Transformation.

The electrochemical stability of MOFs in aqueous medium is most essential for MOFs based electrocatalysts for hydrogen production via water splitting. Since most MOFs suffer from instability issues in aqueous systems, there is enormous demand for electrochemically stable MOFs catalysts. Herein, we have developed a simple postsynthesis surface modification protocol for La (1,3,5-BTC) (H2O)6 metal-organic frameworks (LaBTC MOFs) using Mercaptopropionic acid (MPA), to attain electrochemical stability in aqueous mediums.
