Summary: Visible-light-driven (VLD) BaFe12O19/BiOBr composite catalysts with different mass ratios of BaFe12O19 were prepared using hydrothermal and calcination methods. The S-type heterojunction structure of BaFe12O19/BiOBr enables effective charge transfer and higher redox ability. The obtained composite exhibited excellent photocatalytic activity (95%) in degrading MBT under visible light irradiation for only 3 minutes, surpassing the performance of pure BaFe12O19 (10.6%) and BiOBr (49%). Furthermore, the composites can be magnetically separated, offering practical significance in efficient separation and recovery. Photocatalysis experiments also demonstrated good degradation performance towards TC, CIP, and Eosin. Overall, these separable BaFe12O19/BiOBr composites show promise as candidate materials for sewage purification.

Summary: The design of Z-scheme heterostructure photocatalysts is an effective method for degrading organic pollutants in wastewater. In this study, novel Z-scheme SnS2/Ag3VO4 heterojunction photocatalysts were synthesized for the first time using a simple precipitation method. The microstructures and physicochemical properties of the SnS2/Ag3VO4 nanohybrids were extensively characterized. The SnS2/Ag3VO4 heterojunction exhibited higher photocatalytic activity and stability compared to the pure sample due to the establishment of a Z-scheme heterojunction and effective transportation of photocarriers.

Summary: The novel solid-state Z-scheme photocatalyst Ag3PO4/CSs/AgBr showed wide visible light absorption and superior photocatalytic performance. The carbon spheres (CSs) acted as charge carrier transfer bridge in constructing the all-solid-state Z-scheme photocatalyst, leading to significantly improved photocatalytic performance and stability. The possible photocatalytic reaction mechanism for Ag3PO4/CSs/AgBr involved photogenerated electrons with strong reduction abilities in the conduction band (CB) of AgBr and holes with strong oxidation abilities in the valence band (VB) of Ag3PO4.

Summary: This study fabricated a ZnSe/Ag2Se/AgBr (ZAA) heterojunction by growing ZnSe on AgBr surface and in-situ generating Ag2Se between the two components. The results showed that ZAA exhibited excellent light response ability over the full wavelength range. XPS and ESR confirmed that the charge transfer of ZAA conformed to dual Z-scheme mechanism, with Ag2Se acting as an electron transfer bridge and electron reservoir to accelerate electron transfer and facilitate carriers' separation. The highest CO yield of 54.14 mu mol/g/h was obtained from the optimal ZAA-2, which was 11.76 and 10.44 times of pure ZnSe and Ag2Se, respectively. This work demonstrated the feasibility of a dual Z-scheme heterostructure with full spectrum response for providing stable electron-donating environment and improving electron transfer for enhanced photocatalytic activity.

Summary: We demonstrate that the electrochemically corroded thick nitrogen-doped carbon (N-C) layer encapsulated Pt/C catalyst exhibits high activity and ultrahigh stability for methanol oxidation and oxygen reduction reactions. The encapsulation of thick N-C layers initially results in low activity, but after an aging corrosion process, the activities increase significantly and remain stable. The catalyst also shows high power densities and maintains stability in an acidic membrane fuel cell. The corrosion of the thick N-C layer leads to the formation of micropores, which enhance mass transport and protect Pt particles, thereby improving activity and stability.

Summary: Photocatalysis and piezocatalysis are important catalytic processes widely used in the fields of energy and environmental restoration. Photocatalysis is limited by the rapid recombination of electron-hole pairs, while piezocatalysis can achieve high-efficiency energy conversion through mechanical energy. Piezo-photocatalysis can combine the advantages of the two to improve catalytic efficiency, but there is still a vast knowledge gap for its design, applications, and prospects.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
