TL;DR: Li et al. as mentioned in this paper showed that a heterogeneous catalyst with mononuclear manganese embedded in nitrogen-doped graphene (Mn-NG) shows a turnover frequency as high as 214 −1 for chemical water oxidation and an electrochemical overpotential as low as 337 −mV at a current density of 10 −mA−cm−2.

TL;DR: In this article, the authors summarize the applications of various metal-organic frameworks (MOFs) derived electrocatalysts (including MOF-derived single-atom catalysts, and MOFs-derived metal-free catalysts) in fuel cells and metal-air batteries, and discuss how to increase mass density of effective active sites and protect the active sites from damage and corrosion.

TL;DR: Magnetic nanomaterials show promising applications in heterogeneous catalysis because of their ease of separation and good reusability as mentioned in this paper, and the magnetization saturation values of magnetic nanoparticles.

TL;DR: In this article, a series of hybrid optical films of TiO 2 -triethoxysilane-capped polythiourethane (TCPTU) with high refractive indices have been prepared via an in situ sol-gel method.

TL;DR: In this article, defect engineering, heterostructure formation, and heteroatom doping are summarized for improving the performance of 2D catalysts in the hydrogen evolution reaction (HER).
