Summary: Iron porphyrin catalysts are widely used in CO2 reduction reactions, but powering them with photosensitizers still faces challenges. In this study, we designed an iron porphyrin catalyst decorated with urea functions, which acted as a hydrogen bonding scaffold to enhance the photocatalytic activity. The results showed that the catalyst exhibited remarkable photocatalytic activity, and experimental evidence demonstrated the involvement of Fe-I species in the CO2 activation process.

Summary: By decorating iron porphyrins with imidazolium pendants, a family of multifunctional secondary coordination sphere groups is developed to enhance catalytic performance in synthetic systems. In the electrochemical CO2 reduction reaction (CO2RR), these imidazolium units promote multiple synergistic effects to increase CO2RR activity. The study also reveals that through-space charge effects have a stronger impact on catalytic CO2RR performance than hydrogen bonding in this context.

Summary: The development of catalysts for converting CO2 to useful products is a challenging task. This study investigates the influence of the position and number of hydroxyphenyl groups in iron porphyrins on CO2-to-CO conversion. The results show that iron porphyrins with 5,15-bis(2,6-dihydroxyphenyl) substitution are superior electrocatalysts for CO2 reduction in N,N-dimethylformamide solvent. Calculations and analyses of vibrational frequencies, optical spectra, and reduction potentials provide insights into the factors that affect catalyst performance.

Summary: Metal-porphyrin complexes with different substituents were prepared and anchored on carbon nanotubes for high electrochemical CO2 reduction performance. CoTCMePP/CNTs exhibited a higher CO selectivity, current density, and turnover frequency compared to CoTCPP/CNTs. Similarly, CoTOMePP/CNTs showed superior CO selectivity and stability than CoTOPP/CNTs, attributed to increased solubility and reduced aggregation of the methylated derivatives.

Summary: 2,5-Furandicarboxylic acid (FDCA) is an eco-friendly substitute for fossil fuel-derived polymers that can be produced from biowaste. This study focuses on the electrochemical oxidation method to convert hydroxymethylfurfural (HMF) into FDCA using a reactive analogue of aminoxyl radical (TEMPO) as an anodic catalyst. The immobilization procedure allows the TEMPO catalyst to function heterogeneously, eliminating the need for catalyst separation and recycling. The catalyst showed excellent performance, with a low onset potential and high faradaic efficiency, and can be adapted to other oxidative organic electrochemical reactions.

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.
