Summary: Highly photoactive FeVO4 photoanodes with ordered nanoblock morphology and uniform Ti-doping were prepared, showing enhanced photocurrent and overall water splitting activity. The Ti4+ successfully doped into the FeVO4 lattice by substituting V5+ increased the number of O-2(-) vacancies, leading to improved charge carrier concentration and conductivity, and facilitated charge transfer kinetics.

Summary: The study demonstrates that modification of hematite electrodes can enhance their activity in photoelectrocatalytic oxidation reactions, especially in the oxidation of glycerol. Results from intensity-modulated photocurrent spectroscopy suggest that the increased activity is due to the higher rate of charge transfer and efficient suppression of electron-hole pair recombination in the oxidation process.

Summary: A novel Ti3+ self-doped and nitrogen-annealed TiO2 nanocone arrays (Ti3+-TiO2NCs(N2)) photoanode was prepared for efficient photoelectrocatalytic degradation of sulfamethazine (SMT) under visible light. The visible light harvesting and charge transfer of TiO2 nanocones were significantly improved after nitrogen annealing treatment. The introduction of Ti3+ sites lowered charge transport resistance and introduced a new impurity energy level, resulting in accelerated transmission of photogenerated carriers and enhanced degradation of pollutants.

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.
