TL;DR: In this article, the hydrogen (H2) and oxygen (O2) fuel cell is the one with zero carbon emission and water as the only byproduct, which is essential to ensure higher life cycle and less decay in cell efficiency.

TL;DR: In this paper, the authors have discussed the use and validity of ten important parameters, namely overpotential at a defined current density, iR-corrected over-potential, Tafel slope, exchange current density (j0), mass activity, specific activity, faradaic efficiency (FE), turnover frequency (TOF), electrochemically active surface area (ECSA), and measurement of double layer capacitance (Cdl) for different electrocatalytic materials that are frequently employed in both oxygen evolution reaction (OER) and HER.

TL;DR: In this article, a detailed view on the basics of oxygen evolution reaction (OER) electrocatalysis, evaluation perspectives, current trends in OER electrocalysis, evolution of these layered double hydroxides (LDH) materials as OER catalysts, activity trends, relationship among structure, activity and mechanism, trends in the synthesis methodologies, dominance of Ni-Fe LDH materials in electrochemical and photoelectrochemical water splitting, challenges and opportunities have been elaborated in detail.

TL;DR: In this paper, NiFe layered double hydroxide (LDH) with Pt NPs was achieved following a two-step reaction, viz., the hydrothermal preparation of highly crystalline NiFe LDH sheets and the homogenous reduction of Pt4+ ions with borohydride in a solution of homogenized NiFeLDH crystalline sheets.

TL;DR: In this paper, a review on how to overcome the extensive issues faced by LDHs in terms of synthetic and exfoliation methods and discusses various strategies developed in recent years in the field of the electrocatalytic water-based oxygen evolution reaction.
