The ratiometric electrochemical sensors have been highly explored to minimize system errors and environmental interference. However, it is extremely desirable on the development of an effective ratiometric electrochemical sensor in a facile approach without the complicated assembly process. In this work, an effective internal reference probe was coupled based on the polymerized thionine (pTh) via...
Development of one dimensional covalent organic frameworks (1D‐COFs) with potential in light absorption and catalysis is still challenging, due to their rapid interpenetration to form 2D and 3D porous structures. Here we report a successful synthesis of imine‐linked 1D covalent organic ribbons (COR), using two simple linear building blocks 1,4‐Benzenediamine (Bda) and [2,2′‐Bipyridine]‐5,5′‐dicarbaldehyde...
With the rapid development of performance and long‐term stability, bismuth vanadate (BiVO4) has emerged as the preferred photoanode in photoelectrochemical tandem devices. Although state‐of‐the‐art BiVO4 photoanodes realize a saturated photocurrent density approaching the theoretical maximum, the fill factor (FF) is still inferior, pulling down the half‐cell applied bias photon‐to‐current efficiency...
