“…As shown in Figure S3 (Supporting Information), all N 1s peaks of X‐ray photoelectron spectroscopy (XPS) spectra can be deconvoluted into two peaks, which are assigned to C−N bonds (398.8 eV) and −C≡N (400.2 eV), respectively. [ 15,16 ] Also, significant peaks appear in the C 1s and O 1s high‐resolution spectra of PBNCZ‐COO − , proving the existence of −COO − (287.9 and 531.0 eV). [ 17–19 ] We also determined the content of C, N, and H in the polymer by combustion elemental analysis.…”

Advanced oxidation processes (AOPs) using hydroxyl radicals (•OH) as oxidizing agents are a promising technology. Herein, a feasible strategy is developed to initially construct carbazole‐based D‐π‐A type conjugated polymer (PBNCZ) via the oxidative coupling. Additionally, introducing ─COO− through Cyano hydrolysis extends its conjugated structure and improves the energy band structure, which greatly facilitates the generation of •OH as well as the enrichment of pollutants. Detailed experiments and theoretical calculations have proved that the introduction of ─COO− enhances the adsorption of O2 and bisphenol A (BPA), optimizing the reaction path of •OH. Thus, it completely decomposes 10 ppm of BPA within just 10 min, exceeding all previously organic photocatalysts. Meanwhile, the efficiency of photocatalytic H2O2 production by PBNCZ‐COO− reaches 1719.03 µmol h−1 g−1 under visible light. This multifunctional material with high adsorption capacity, photodegradation efficiency, and photocatalytic H2O2 production activity provides a solid foundation for the preparation of organic photocatalysts.

“…The entire length of the coastline affected by the oil spill was 786.5 km (including the coastline of the islands), which impacted the local fisheries and the ecological environment. More and more people have recently paid attention to film-separation technology, 3 because of its advantages of good separation effect, average temperature, simple, and economical separation technology, [4][5][6] and its application in the treatment of water pollution. 7 Traditional polymer-film-treatment technology is simple to operate, environmentally friendly, low-cost, and shows good applications in water treatment.…”

“…Rising temperature caused the change of the first layer from "open (hydrophilic)" to "closed (hydrophobic)", but the second layer and the third layer work normally, enabling the substrate into these layers for hydrolysis-reduction tandem reactions. Therefore, through this self-commutation, the catalytic reactor presents the changeable processes from simple catalysis to tandem catalysis [25,26]. In this research, the thermosensitive hydrogels are using as the carriers for different kinds of catalytic reactors, which could provide a new platform for the catalytic reactor in self-controlled processes.…”

The present endeavor is to develop a highly-intelligent catalytic reactor prototype which is able to autonomously adapt to the environment and provides an in-situ double-shift catalytic ability. By seeking inspiration from nature, this objective is achieved by developing a self-adaptive hydrogel catalytic reactor which held a catalytic trilaminar structure capable of reverse thermosensitive properties. With increasing temperatures, the catalytic tri-layers of this catalytic reactor would function in a sequential way (i.e., one negative temperature response layer, one support layer and one positive temperature response layer) and as a result, led to the single-tandem double-shift catalytic ability. This catalytic reactor individually presented single/tandem catalytic process at relatively low temperatures or high temperatures through the cooperative work of the three layers. In this way, this catalytic reactor showed the single-tandem controllable catalytic ability. The novel protocol not only provides a new solution to complicated catalytic processes but also inspires the further application of smart polymers in a broader spectrum of areas.
