Quaternization of a Triphenylamine-Based Conjugated Porous Organic Polymer to Immobilize PtCl62– for the Photocatalytic Reduction of 4-Nitrophenol

“…have been developed, but these supports are still restricted owing to the weak interaction between supports and MNPs, which decreases the chemical stability of the photocatalyst. − Moreover, another point most previous works have ignored is whether the introduction of support has broadened the light absorption region and improved the light absorption ability of the photocatalyst, which also highly influences the final conversion efficiency. Recently, conjugated porous organic polymers (POPs) have achieved great attention and been widely used in diverse applications including adsorption, , separation, photocatalytic degradation, − energy storage, , electrocatalysis, − etc., but rarely applied in the reduction of 4-NP to our best knowledge. Owing to conjugated structures, porous skeletons, and excellent chemical stability, POPs are promising supports in the efficient photocatalytic reduction of 4-NP to generate 4-AP, meeting the three primary requirements of improved dispersity, enhanced chemical stability, and more efficient photocatalytic performance.…”

Azobenzene-Phenazine-Based D–A Polymer as a Highly Efficient Bipolar Cathode for Sodium-Ion Batteries

“…The n-type feature of azobenzene can reduce the HOMO energy level of ABPZ and elevate the redox potential. Moreover, the azo unit can undergo a two-electron redox reaction, thus providing additional capacity . Results demonstrate that ABPZ shows excellent performance as a cathode in the half-cell, providing a reversible specific capacity up to 283 mAh/g at 1.0–4.0 V (vs Na + /Na), quite close to the theoretical specific capacity (296 mAh/g), suggesting a high active site utilization.…”

Moreover, a capacity retention of 91.7% after 300 cycles indicates that polymerization successfully retards the dissolution of the electrode material in the electrolyte, contributing to the stable cycling of the cell.…”

Biomass Waste Utilization as Nanocomposite Anodes through Conductive Polymers Strengthened SiO2/C from Streblus asper Leaves for Sustainable Energy Storages

“…The capacity provided by the capacitive effect could be determined by constructing log(i)−log(v) curves according to Equation (10) and calculating the slope of the line (b value). According to prior research, as b approaches 0.5, a process is governed by complete diffusion, and when b approaches 1, the process is capacitive [62,63]. Therefore, by establishing the value of b, the battery's major contribution could well be quantified.…”
