Nonplanar porphyrins with out‐of‐plane distortions play crucial roles in many biological functions and chemical applications. The artificial construction of nonplanar porphyrins usually involves organic synthesis and modification, which is a highly comprehensive approach. However, incorporating porphyrins into guest‐stimulated flexible systems allows to manipulate the porphyrin distortion through...
A fundamental understanding of metal active sites in single‐atom catalysts (SACs) is important and challenging in the development of high‐performance catalyst systems. Here, a highly efficient and straightforward molten‐salt‐assisted approach is reported to create atomically dispersed cobalt atoms supported over vanadium pentoxide layered material, with each cobalt atom coordinated with four neighboring...
The facile creation of high‐performance single‐atom catalysts (SACs) is intriguing in heterogeneous catalysis, especially on 2D transition‐metal dichalcogenides. An efficient spontaneous reduction approach to access atomically dispersed iron atoms supported over defect‐containing MoS2 nanosheets is herein reported. Advanced characterization methods demonstrate that the isolated iron atoms situate...
Selective aerobic oxidation of alcohols offers an attractive means to address challenges in the modern chemical industry, but the development of non‐noble metal catalysts with superior efficacy for this reaction remains a grand challenge. Here, this study reports on such a catalyst based on atomically defined undercoordinated copper atoms over nitrogen‐doped carbon support as an efficient, durable,...
Photodynamic therapy (PDT) has shown great potential for tumor treatment with merits of non‐invasiveness, high selectivity, and minimal side effects. However, conventional type II PDT relying on 1O2 presents poor therapeutic efficacy for hypoxic tumors due to the oxygen‐dependent manner. Alternatively, emerging researches have demonstrated that type I PDT exhibits superiority over type II PDT in tumor...
3D graphene frameworks/Co3O4 composites are produced by the thermal explosion method, in which the generation of Co3O4 nanoparticles, reduction of graphene oxide, and creation of 3D frameworks are simultaneously completed. The process prevents the agglomeration of Co3O4 particles effectively, resulting in monodispersed Co3O4 nanoparticles scattered on the 3D graphene frameworks evenly. The prepared...
The development of earth‐abundant, active, and stable catalysts is important for solar energy conversion. Metal‐organic frameworks (MOFs) have been viewed as a promising class of porous materials, which may have innovative application in photocatalysis. In this paper, three types of Fe‐based MOFs and their aminofunctionalized derivatives have been fabricated and systematically studied as water oxidation...
Planar heterojunction perovskite solar cells with a high efficiency up to 17.76% are fabricated by modifying the compact TiO2 (c‐TiO2) with a [6,6]‐phenyl‐C61‐butyric acid (PCBA) monolayer. High quality CH3NH3PbI3 films can be easily fabricated on PCBA‐modified c‐TiO2 substrates by a one‐step solution processing method. Significant improvements of the device parameters are observed after PCBA modification...
