TL;DR: In this paper, the ozone removal rate of α-MnO2 nanofiber with high concentration of surface oxygen vacancy was obtained via vacuum deoxidation method, where the formation of oxygen vacancy enhanced the ratio of Mn3+/Mn4+, resulting in a significant improvement of the adsorption of ozone on the surface of the catalyst.

TL;DR: The performance of the catalyst has been improved because the abundant active oxygen vacancies are fabricated by the electrostatic interaction between oxygen atoms inside the tunnels and the introduced K+, which offers a new perspective to design a high efficiency catalyst and may promote manganese oxide for practical ozone elimination.

TL;DR: In this article, the authors introduce the limiting factors for the photocatalytic efficiency of 3D network photovoltaics and their corresponding solutions, and summarize the most common 3D photocatalyst and their synthetic strategies.

TL;DR: In this article, a photocatalysis-self-Fenton system was constructed to achieve high-fluent degradation and high mineralization performance, based on in-situ generated H2O2 over graphitic carbon nitride (g-C3N4) under visible-light irradiation.

TL;DR: In this paper, a hierarchical structure consisting of graphene encapsulating α-MnO2 nanofiber was developed to solve the low stability and water inactivation problems of ozone decomposition, which exhibited a stable ozone conversion efficiency of 80% and excellent stability over 100'h under a relative humidity (RH) of 20%.
