Materials Today Energy 

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 article, the authors investigated the energy storage capacity of rechargeable Zn/MnO2 battery chemistry in mildly acidic aqueous electrolytes and found that the dissolution-deposition reaction mechanism is dominant for the ZnSO4+MnNSO4 electrolyte, while the classical cations (H+, Zn2+) Intercalation/De-intercalation mechanism contributes little capacity in energy storage process.

TL;DR: In this article, the photothermal effect of different categories of light absorbing materials is reviewed and discussed, and applications of a series of representative photothermal materials for solar-steam generation are introduced and summarized in detail to reflect the state-of-the-art for solar evaporation.

TL;DR: In this paper, the progress of perovskite solar cells with a particular emphasis on fabrication processes and instrumentation that have scale-up potential is reviewed, focusing on lifetime measurement and quantification protocols for commercialization.

TL;DR: In this article, a comprehensive review of metal sulfide-based semiconductors for the degradation or decomposition of dyes in wastewater industries with low cost, environment-friendly and sustainable treatment technologies for the environmental protection is presented.
