Aiming at regulating and controlling the localized electronic states while maintaining the metal atoms in the isolation form, an in situ adsorbate induced strategy is proposed at a programmed temperature to activate Zr‐based metal–organic framework (MOF) supported single Pd atom catalyst. It is discovered that in situ treatment environments trigger the change of lattice parameters in MOF materials...
Flexible Supercapacitors
In article number 2102054, Tao Chen and co‐workers report an efficient strategy to suppress the self‐discharge behavior of flexible supercapacitors by building a heterogeneous polyanion/polycation electrolyte between two electrodes. The electrostatic repulsive effect between the charged polyelectrolytes and movable ions endows the charged supercapacitors with longer self‐discharge...
Supercapacitors with high power density and an ultralong cyclic lifetime have been intensively investigated. However, the crucial challenge of their rapid self‐discharge process is often neglected in most cases. A heterogeneous interface formed between two layers of polymer electrolytes is designed, in which a polyanion and a polycation are added into a common matrix of polymer electrolyte, respectively...
Photodynamic therapy (PDT), which utilizes photosensitizer to convert molecular oxygen into singlet oxygen (1O2) upon laser irradiation to ablate tumors, will exacerbate the already oxygen shortage of most solid tumors and is thus self‐limiting. Herein, a sophisticated photosensitive polymeric material (An‐NP) that allows sustained 1O2 generation and sufficient oxygen supply during the entire phototherapy...
Precious metals such as palladium (Pd) and platinum (Pt) are marvelous materials in the fields of electronic and catalysis, but they are tapering day by day. Zr(IV)‐based metal–organic frameworks (MOFs) are competent for their recovery, notably in harsh environments, while the general powder form limits their practical application. Porous MOF‐based membranes with ultraefficient metal ion permeation,...
Metal–Organic Framework (MOF)–polymer compatibility is a thorny issue in practical applications. In article number 1805242, Hak Yong Kim, Yeoung‐Sang Yun, and co‐workers investigate Zr(IV)‐based MOF membranes for precious metal recovery in a strongly acidic environment. The fibrous membranes show outstanding performances, and good stability attributing to strong π–π interactions between polymer chains...
