Summary: A novel catalyst consisting of multi-atom Pt metal centers stabilized by atomically dispersed ZnFe-NC support through Pt-N bonds is reported, showing high stability, 100% exposure of surface Pt atoms, and excellent fuel cell performance. The catalyst combines the advantages of single-atom catalysts (SACs) and nanoparticles (NPs), achieving a maximal power output of 1.02 W cm-2 with an ultralow Pt loading of 0.035 mg cm-2 at the cathode. DFT calculations reveal the critical role of the strongly coupled Pt-N bond in stabilizing the cross-linked Pt structure.

Summary: In this study, indium (In) ions were introduced into flexible Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells to modify the back interface and passivate deep level defects in CZTSSe bulk. The results showed that In doping effectively inhibited the formation of secondary phase and V-Sn defects, decreased the barrier height at the back interface, passivated deep level defects in CZTSSe bulk, increased carrier concentration, and significantly reduced the V-OC deficit. Eventually, a flexible CZTSSe solar cell with a power conversion efficiency of 10.01% was achieved. This synergistic strategy of interface modification and bulk defects passivation through In incorporation provides a new approach for fabricating efficient flexible kesterite-based solar cells.

Summary: This study systematically investigates the key roles of Nafion on Cu nanoparticles electrocatalyst for CO2RR. The Nafion modifier suppresses the hydrogen evolution reaction, increases CO2 concentration and mass transfer process, and activates CO2 molecule to enhance C2 product generation. As a result, the selectivity of the hydrogen evolution reaction is reduced and the efficiency of C2 products is significantly improved.

Summary: Direct growth of redox-active noble metals and rational design of multifunctional electrochemical active materials play crucial roles in developing novel electrode materials for energy storage devices. In this regard, silver (Ag) has attracted great attention in the design of efficient electrodes. The construction of multifaceted heterostructure cobalt-iron hydroxide (CFOH) nanowires (NWs)@nickel cobalt manganese hydroxides and/or hydrate (NCMOH) nanosheets (NSs) on the Ag-deposited nickel foam and carbon cloth (i.e., Ag/ NF and Ag/CC) substrates is reported. The as-fabricated Ag@CFOH@NCMOH/NF electrode delivered superior areal capacity value of 2081.9 μA h cm-2 at 5 mA cm-2. Moreover, as-assembled hybrid cell based on NF (HC/NF) device exhibited remarkable areal capacity value of 1.82 mA h cm-2 at 5 mA cm-2 with excellent rate capability of 74.77% even at 70 mA cm-2. Furthermore, HC/NF device achieved maximum energy and power densities of 1.39 mW h cm-2 and 42.35 mW cm-2, respectively. To verify practical applicability, both devices were also tested to serve as a self-charging station for various portable electronic devices.
