Summary: Plasma-assisted dry reforming of methane is a promising method to produce syngas with unity H2/CO ratio. The design of efficient catalyst materials is of great importance to establish a match between CH4 and CO2 activation rates. Addition of La to the highly ordered mesoporous 10Ni5LaAl-one pot catalyst enhanced reducibility of Ni2+ species and promoted Ni dispersion, resulting in the highest catalytic activity and cokeresistance ability. Stability performance was achieved due to higher discharge power, efficient capacitance, and lower apparent activation energy of CO2 under plasma condition. A possible reaction mechanism was proposed for the 10Ni5LaAl-one pot catalyst during plasma-catalytic dry reforming process.

Summary: Catalytic methane decomposition (CMD) is a promising technology for producing H2 and carbon nanostructures. In this study, Ni/Al2O3-La2O3 yolk-shell catalysts were synthesized and tested for photothermal CMD. The addition of an optimal amount of La improved the catalyst's performance and H2 yield, and also promoted the growth of carbon nanofibers. Moreover, the introduction of light irradiation increased the H2 yield and suppressed CO co-production. This work demonstrates the potential of photothermal catalysis for CMD and provides insights into the role of modifiers in methane activation on Al2O3-based catalysts.

Summary: Chemical looping reforming coupled with CO2 splitting is a promising method for CO2 utilization, producing valuable fuel. Researchers have developed a novel perovskite oxide (La0.6Ca0.4Fe0.95M0.05O3-delta, M = Ni, Co, Ni-Co) that acts as both an oxygen carrier and a redox catalyst. Through various techniques, they observed the spontaneous formation of alloy nanoparticles on the surface of the co-doped carriers in a CH4 atmosphere. These co-doped samples showed high reactivity towards both gases and demonstrated excellent coking and redox stability, achieving record-level syngas yield.

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: 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.
