Summary: Metal molybdates, inheriting the characteristics of polyoxometalates, have been widely used in various fields. However, the construction of hierarchical molybdate nanostructures with superior performance remains a challenge. In this study, hierarchical manganese molybdate nanocauliflowers were synthesized from aggregated microrods using dopamine as a scissor, and a carbon coating layer was introduced through a simple calcination. The MnMoO4/C nanocauliflowers exhibited excellent electrochemical properties as anodes for lithium/sodium ion batteries, surpassing the performance of bare MnMoO4. The stable cyclic property without obvious capacity fading was also superior to previous reports. This study demonstrates a simple yet effective strategy for structure engineering and surface modification of molybdates.

Summary: In this study, a vanadium dioxide/ graphene oxide (VO2(B)/GO) sample was constructed through hydrothermal route, which exhibited remarkable rate capability. The presence of oxygen vacancies in VO2(B)/GO weakened the electrostatic force, while GO prevented vanadium oxidation. The electrode showed a high reversible capacity of 423 mAh g-1 at 0.5 A g-1 and maintained long-life cycling properties at 15 A g-1. The combination of oxygen vacancies and GO contributed to excellent performance and prevented the collapse of VO2 structure during cycling. VO2(B)/GO also exhibited excellent performance in all-climate conditions (-15-60 degrees C).

Summary: In this study, a charge-transfer complex electrolyte additive, 7,7,8,8-tetracyanoquinodimethane (TCNQ), with high affinity for zinc was used to form a dense and robust interfacial complex layer on the zinc anode, suppressing the activity of H(2)O. The complex layer enabled the formation of a Zn-Zn-(TCNQ)(2) Ohmic contact interface, facilitating rapid ion/electron transport, improving electric field distribution, and preventing direct contact between active H2O and the zinc anode, resulting in a dendrite-free zinc anode and efficient zinc plating/stripping kinetics. As a result, the Zn||Zn symmetrical cell exhibited high plating/stripping reversibility for over 1000 hours at 20 mA cm(-2) and 5 mA h cm(-2), and a high depth of discharge of 43%. Furthermore, the Zn||MnO2 full cell demonstrated a high capacity of 143.3 mA h g(-1) at 2000 mA g(-1) even after 4000 cycles, with a capacity retention of 94.7% after returning to 100 mA g(-1).

Summary: To improve the performance of perovskite solar cells (PSCs), researchers have used passivators to address the defects of perovskite. In this study, a passivator called TA-MN, which has a symmetric bidentate acceptor, was found to have a strong synergistic passivating ability due to the presence of two symmetric cyano groups (CN). This passivator achieved a higher power conversion efficiency (PCE) of 21.19% compared to the TA-CA passivator (20.54%) and the control group (19.49%). The TA-MN-based PSCs also demonstrated good stability and scalability. These findings provide useful insights for the design of passivators with symmetric bidentate acceptors.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
