“…Here, a piece of FTO conducting glass deposited with a 350 nm-thick conductive film of fluorine-doped tin oxide was dipped into acetone and isopropanol successively for 30 min, then dried to serve as the front electrode. The surface of the FTO-glass is roughly textured ( Supplementary Figure 5A ), as a result of the low symmetric tetragonal crystal structures of fluorine-doped tin oxide ( Zhang et al, 2018 ). This structure is similar to the wrinkles on the surface of the bacterial plasma membrane, which facilitates attachment of the photosynthetic complexes ( Csiki et al, 2018 ).…”

Roseiflexus castenholzii is an ancient green non-sulfur bacteria that absorbs the solar energy through bacteriochlorophylls (BChls) bound in the only light harvesting (LH) complex, and transfers to the reaction center (RC), wherein primary charge separation occurs and transforms the energy into electrochemical potentials. In contrast to purple bacteria, R. castenholzii RC-LH (rcRC-LH) does not contain an H subunit. Instead, a tightly bound tetraheme cytochrome c subunit is exposed on the P-side of the RC, which contains three BChls, three bacteriopheophytins (BPheos), two menaquinones, and one iron for electron transfer. These novel structural features of the rcRC-LH are advantageous for enhancing the electron transfer efficiency and subsequent photo-oxidation of the c-type hemes. However, the photochemical properties of rcRC-LH and its applications in developing the photo-bioelectrochemical cells (PBECs) have not been characterized. Here, we prepared a PBEC using overlapped fluorine-doped tin oxide (FTO) glass and Pt-coated glass as electrodes, and rcRC-LH mixed with varying mediators as the electrolyte. Absence of the H subunit allows rcRC-LH to be selectively adhered onto the hydrophilic surface of the front electrode with its Q-side. Upon illumination, the photogenerated electrons directly enter the front electrode and transfer to the counter electrode, wherein the accepted electrons pass through the exposed c-type hemes to reduce the excited P+, generating a steady-state current of up to 320 nA/cm2 when using 1-Methoxy-5-methylphenazinium methyl sulfate (PMS) as mediator. This study demonstrated the novel photoelectric properties of rcRC-LH and its advantages in preparing effective PBECs, showcasing a potential of this complex in developing new type PBECs.

ZnO exhibits various properties, and fabrication of ZnO (including doped ZnO) films are required for device and energy applications. Metals such as stainless steel (SUS) are promising substrates, but deposition of flat films is difficult on as-received metals because of surface roughness. In addition, when films are deposited directly on metals, the electrical resistance is dominated by the substrate. To overcome these problems, solution deposition planarization (SDP) was investigated for SUS. SiO2 solution was spin-coated and heat-treated in air to prepare a flat SDP layer. Flat polycrystalline films of Al-doped ZnO (AZO) were fabricated on the SDP layer. The electrical resistance of AZO/SDP/SUS was determined by AZO, the influence of the SUS is not observed. Thus, the insulation and planarization were simultaneously achieved by the SDP layer. This study shows that polycrystalline AZO films can be deposited on metals with the SDP without a complicated intermediate multilayer structure.

“…SnO 2 has a high photochemical property and stability, and is extensively studied in the fields of Li-ion batteries [ 29 , 30 , 31 ], dye sensitized solar cells [ 32 , 33 , 34 ], and gas sensors [ 35 , 36 , 37 ]. Additionally, many studies have shown that the SnO 2 /α-Fe 2 O 3 heterogeneous catalyst has an excellent photodegradation activity.…”

The x-SnO2/α-Fe2O3 (x = 0.04, 0.07, and 0.1) heterogeneous composites were successfully prepared via a two-step solvothermal method. These composites were systematically characterized by the X-ray diffraction technique, field emission scanning electron microscopy, an energy dispersive spectrometer, X-ray photoelectron spectroscopy and a UV–visible spectrometer. It was found that SnO2 nanoparticles were uniformly decorated on the surface of α-Fe2O3 particles in these heterogeneous composites. A comparative study of methylene blue (MB) photodegradation by α-Fe2O3 and x-SnO2/α-Fe2O3 composites was carried out. All x-SnO2/α-Fe2O3 composites showed higher MB photodegradation efficiency than α-Fe2O3. When x = 0.07, the MB photodegradation efficiency can reach 97% in 60 min. Meanwhile, the first-order kinetic studies demonstrated that the optimal rate constant of 0.07-SnO2/α-Fe2O3 composite was 0.0537 min−1, while that of pure α-Fe2O3 was only 0.0191 min−1. The catalytic mechanism of MB photodegradation by SnO2/α-Fe2O3 was examined. The SnO2 can act as a sink and help the effective transfer of photo-generated electrons for decomposing hydrogen peroxide (H2O2) into active radicals. This work can provide a new insight into the catalytic mechanism of the photo-Fenton process.
