Preparation of CeO2/PbFe12O19 (CO/PFO) heterojunction photocatalysts with the different CO contents as visible‐light photocatalysts were synthesized by a polyacrylamide gel route combined with a low temperature sintering technique. A variety of characterization techniques have been used to confirm that the CO/PFO heterojunction photocatalysts contain only Ce, Pb, Fe and O elements, which also indicates that the special interfacial contact between CO and PFO is formed and there are a large number of oxygen vacancies and interfacial defects in CO/PFO heterojunction photocatalysts. The coupling of CO and PFO enhances the optical absorption coefficients of CO and PFO and slightly decreases the optical band gap (Eg) of the host lattice (PFO). Rhodamine B (RhB), phenol, bisphenol A (BPA) and oxytetracycline hydrochloride (OTC‐HCl) were used as target degradation pollutants to investigate the degradation preference of CO/PFO heterojunction photocatalysts. The degradation percentages of the RhB, Phenol, BPA and OTC‐HCl are 20.35 %, 38.77 %, 18.11 % and 75.32 %, respectively. The results showed that the hydroxyl radical played a dominant role in the degradation of pollutants by the CO/PFO heterojunction photocatalysts and preferred to degrade −C=O and −CONH2. This new idea will provide technical support for cutting functional groups of pollutants purposefully.

“…As shown in Figure 4d, samples were irradiated with a monochromatic light (780 nm), and PL emission was observed due to the recombination of photogenerated charges. [50,51] The emission spectra showed that near band edge emission of FTO/CBO was reduced after Ag + -ions doping. Additionally, the emission of NACBO photoelectrode was further lowered when NiO-HSL was introduced at the back interface to extract the photogenerated holes.…”

CuBi2O4(CBO) has received considerable attention owing to its ideal optical bandgap and positive photocurrent onset potential. However, CBO photocathodes exhibit poor charge carrier separation and transfer across the conducting substrate interface. Herein, a systematic incorporation of Ag+‐cations into nanosized porous CBO network (ACBO) using a simple pulsed‐electrodeposition method. In ACBO photocathode, the Ag+‐ions replace the Bi3+‐ions, thereby building an increased hole concentration, which further signifies the photogenerated electron‐hole separation. Additionally, introducing a low‐cost NiO hole‐selective layer between ACBO and the conducting substrate enables a back‐interface‐aided hole‐extraction and electron blocking, resulting in an improved charge transfer across the back interface. Compared with an unmodified CBO, the NiO/ACBO photocathode exhibits a three‐fold enhanced photocurrent performance. This enhances the photocurrent originating from the incorporation of a substantial amount of Ag+‐ions into the CBO structure, leading to an increased acceptor density as well as the formation of an appropriate hole‐selective layer across the back‐contact. The absorption percentage, time‐resolved photoluminescence, and photoelectrochemical impedance spectroscopy measurements unveil the potential light harvesting, charge separation, and transfer characteristics of the NACBO photoelectrode, respectively. Through this systematic study, an efficient and simple strategy is determined for developing ternary metal oxide‐based photocathode/photoanode systems for sustainable energy applications.

“…Self‐healing rubbers that intrinsically heal through chemical means such as the Diels–Alder mechanism, 3,4 disulphides exchange, 5–7 metal–ligand coordination, 8–10 hydrogen interaction, 11–13 as well as supramolecular ionic networks 14–16 have dominated self‐healing research until now 17,18 . Recently, incorporating the ionic interactions into epoxidized natural rubber (ENR) has shown to be an effective strategy for inducing self‐healing characteristics in the rubber material 12 .…”

A series of intrinsic self-healing natural rubber (NR) integrated with thermoreversible (zinc) Zn 2+ salt bonding networks was successfully fabricated via reversible ionic interaction approach. The formation of Zn 2+ salt bonding in the rubber networks was evidenced by FTIR analysis. The developed materials showed excellent self-healing capability as the properties could recover up to 76% under tensile mode and 100% under tear mode and fatigue. The crosslink density of self-healing NR-g-MAA/ZT rubber obtained from the swelling test evident that interaction between NR-g-MAA and zinc thiolate (ZT) increased with the self-healing ability of the materials. SEM images suggested the occurrence of chain diffusion between the fracture interfaces when the broken pieces were brought in contact with each other's. The reconnection of ionic salt bonding is expected to allow rearrangements of rubber segments, which turns NR-g-MAA into potential self-healing rubber materials.
