“…However, the XRD intensity of the catalyst after being doped was lower than undoped, indicating that Mn was successfully doped to the Zn site in the Zn(O,S) host lattice to disturb the lattice flatness. All the peaks located between those of ZnO (JCPDS#65-2880) and ZnS (JCPDS#05-0566) showed a cubic crystal structure, similar to our previous work [8]. The peaks at 29.36, 48.85, and 58.38̊ can be assigned as (111), (220), and (311) planes, respectively.…”

“…After introducing 10% Mn-doped Zn(O,S) catalyst without ethanol, the absorbance did not decrease furthermore, as shown in figure 4c and the reduction did not obviously happen. This can be explained as that more hydrogen ions for the significant 4-NP reduction are needed, while the reduction reaction to produce hydrogen ion was very low without using ethanol as sacrificial reagent, as shown in our previous reports [8,12,14]. The figure 5d shows the 4-NP reduction in the presence of 10% Mn-doped Zn(O,S) with 10% ethanol.…”

“…When the damage regions of samples are soaked with a dip of water, it is observed that the healing times of P-rGOA, P-1.5, and PEDOT:PSS are measured about 9, 6, and 1 s, until the response currents recover to their initial values. [48] Further, two shoulder-like peaks can be identified at 1024.2 and 1047.1 eV, suggesting that Zn element is in its more oxidized form than ZnO. These reveal that the healing time decreases with increasing PEDOT:PSS content, in other words, the high PEDOT:PSS concentration in samples promotes the healing and decreases the healing time.…”

A versatile composite aerogel is developed by introducing of PEDOT:PSS in reduced graphene oxide, resulting in an ultrathin aerogel film around 100 µm thick. Like a tape, the aerogel can tightly attach to smooth or rough substrate, and there forms a self‐healable and anti‐vibration energy storage electrode. With a Ti foil substrate, the electrode offers an electrochemical capacity of 190 mF cm−2 at 0.1 mA cm−2 working current density. It also exhibits 98.7% capacitance retention after 10 000 charge/discharge cycles, with almost negligible capacitance decline even after eight damaging/healing cycles or 4000 vibrating cycles. With symmetrical aerogel‐based electrodes, a smart electrochemical device is explored as a sensor for sensitively detecting space electric field strength, ranging from 1100 to 19 000 V m−1. Simulation results verify that the response current in the sensor comes from the internal recombination current in the electrochemical device, which originates from ion recombination near the electrode substrate in space electric field. Further, a validation sensor experiment is designed and realized with affiliated modules, successfully monitoring space electric field.

Tubular bimetal oxysulfide CuMgOS catalyst was prepared using a feasible method at a low process temperature of 95°C. X‐ray diffractometry, X‐ray photoelectron spectrometry, field emission‐scanning electron microscopy, transmission electron microscopy, UV–Vis diffuse reflectance spectroscopy, photoluminescence emission spectrum, and nitrogen adsorption–desorption isotherms were used for CuMgOS characterizations. The CuMgOS reduction activities were investigated through the reduction of heavy metals of Cr (VI), Pb (II) and Hg (II) solutions, and the organic dyes of rhodamine‐B (RhB), methyl orange (MO) and methylene blue (MB) solutions under dark. The results showed that the CuMgOS prepared with an appropriate N2H4 amount for a suitable Cu (I)/Cu (II) ratio exhibited fast reduction activity without adding any reagents, with which the 100 mL Cr (VI), Pb (II) and Hg (II) solutions of 50 ppm were 100% reduced by 20 mg CuMgOS within 4 min, 6 min and 4 min, respectively. The 100 mL RhB, MO and MB solutions of 50 ppm were 100% reduced by 10 mg CuMgOS within 4 min, 5 min and 1 min, respectively, under the existence of NaBH4. CuMgOS displayed excellent chemical stability for the re‐use tests on heavy metal ions and organic dyes. The excellent performance is attributed to CuMgOS bimetal oxysulfide catalyst with active surface reaction centers to interact with reactants, and the carrier hopping between Cu (I) and Cu (II).
