Summary: In this study, facet-defined Cu2SnS3 nanoplates were synthesized and their CO2 reduction capability was controlled by ligands. It was found that thiocyanate-capped Cu2SnS3 nanoplates showed excellent selectivity towards formate with a maximum formate Faradaic efficiency of 92% and partial current densities as high as 181 mA cm(-2) in a flow cell with gas-diffusion electrode. Spectroscopic measurements and theoretical calculations revealed that the high selectivity originated from the favorable adsorption of HCOO* intermediates on cationic Sn sites that were electronically modulated by thiocyanates bound to adjacent Cu sites. This work suggests that well-defined multimetallic sulfide nanocrystals with tailored surface chemistries could be a promising approach for the design of future CO2 reduction electrocatalysts.

Summary: A synthetic protocol of nanoparticle morphology on copper metal-organic frameworks (n-Cu MOFs) is developed, resulting in nanoscale copper oxide aggregates composed of small particulates. The resulting nanosized MOF-derived catalyst (n-MDC) exhibits high Faradaic efficiencies toward ethylene and C2+ products, and shows prolonged stability. Comprehensive analyses indicate that the nanoparticle morphology of pristine Cu MOFs plays a crucial role in improving eCO(2)RR activity.

Summary: This work investigates the theoretical differences and similarities of CO2/CO catalytic reduction reactions in gas, aqueous solution, and aprotic solution. The binding energy serves as a good descriptor for the gaseous and aqueous phases and allows catalysts to be categorized by reduction products. However, descriptors alone are insufficient for mapping in the aprotic phase, requiring the use of a microkinetic model.

Summary: This study presents a new approach for the synthesis of water-dispersible core-shell nanocatalysts using metal-organic frameworks (MOFs). By introducing functionalized nanoclusters during the self-assembly of MOFs, missing-linker deficiencies are induced to fabricate mesoporosity. The resulting nanocatalysts significantly reduce the energy consumption of CO2 capture and achieve a 10-fold improvement in efficiency compared to conventional catalysts.

Summary: In this study, an electronic structure manipulation strategy was employed to electron-rich Bi nanosheets, enabling CO2RR towards formate with high activity, selectivity, and stability in pH-universal electrolytes. The mechanism was unravelled by in situ Raman spectra and computational calculations, revealing the promotion of CO2 activation and enhanced adsorption of *OCHO intermediate by electron-rich Bi. Integration of the electron-rich Bi nanosheets with III-V-based photovoltaic solar cell resulted in an unassisted artificial leaf with a high solar-to-formate efficiency of 13.7%.

Summary: A computational study was conducted to investigate the impact of solvation on the reduction reaction of CO2 to formic acid and carbon monoxide on Pb(100) and Ag(100) surfaces. The results provide insights into how solvation affects the adsorption energies of reaction intermediates. By applying an explicit solvation scheme using a combined DFT/microkinetic modeling approach, the study reveals the selectivity for CO formation on Ag and HCOOH formation on Pb, resolving the discrepancy between theoretical calculations and experimental observations. The detailed analysis of adsorption energies highlights the significance of the total number of hydrogen bonds formed by HCOO in determining the adsorption strength of intermediates and the electrocatalytic activity. The findings underscore the importance of explicit solvation for understanding adsorption and electrochemical reaction phenomena on metal surfaces.

Summary: The electrolysis of dilute CO2 streams is hampered by low concentrations of dissolved substrate and rapid depletion at the electrolyte-electrocatalyst interface. To address this issue, a bio-inspired strategy mimicking the carboxysome in cyanobacteria is introduced. It utilizes microcompartments with nanoconfined enzymes in a porous electrode to accelerate CO2 hydration kinetics and minimize substrate depletion, enabling efficient reduction of low-concentration CO2 to formate even at atmospheric concentrations. This concept demonstrates the potential of the carboxysome as a blueprint for the reduction of low-concentration CO2 streams to chemicals.

Summary: In this study, the electrochemical CO2 reduction reaction (eCO(2)RR) on two intermetallic compounds formed by copper and gallium metals (CuGa2 and Cu9Ga4) is investigated. The results show that CuGa2 exhibits high selective conversion of CO2 to methanol due to its unique 2D structure that retains surface and subsurface oxide species even in the reduction atmosphere. Various characterization techniques are employed to reveal the changes of Ga2O3 species and the mechanism of methanol formation. Additionally, a poly(tetrafluoroethylene)-based gas diffusion electrode is utilized to improve the overall eCO(2)RR performance.

Summary: The construction of NxC shell on the surface of Ag nanoparticle core promotes the formation of CH4 and CH2CH2. The NxC shell does not modify the electronic property of Ag, but increases the residence time of CO intermediates, enhancing C-C coupling and deep reduction. Additionally, activated H2O molecules provide sufficient adsorbed hydrogen for further reduction of carbonaceous intermediates.

Summary: A core-shell structure Ag@NxC is constructed to enhance the formation of CH4 and CH2CH2 during the electrochemical conversion of CO2. The NxC shell prolongs the residence time of CO intermediate, enhancing C-C coupling and deep reduction. In addition, activated H2O molecules provide adsorbed H to further reduce the carbonaceous intermediate. This strategy enables the conversion of CO2 into hydrocarbon products using non-Cu-based catalysts.

Summary: By altering the water activity, researchers discovered that the mechanism of water oxidation is sensitive to the applied potential: a intramolecular oxygen coupling mechanism prevails at low driving force, while a water nucleophilic attack mechanism dominates at high driving force. This observed mechanistic switch has significant implications for understanding and controlling the water-oxidation reaction on heterogeneous catalysts.

Summary: The kinetics of water oxidation in molecular and heterogeneous catalysis differ due to the cooperative effects between oxidized iridium centers in heterogeneous catalysts. The specific coordination environment around the iridium centers in molecular catalysts allows for water oxidation without cooperative effects. These distinctions explain the differences in water oxidation electrocatalytic performance observed under different potential conditions.

Summary: The redox-switchable polymerizations of lactide and epoxides were extended to the solid state by anchoring an iron-based polymerization catalyst to TiO2 nanoparticles, allowing for surface-initiated polymerization reactions that produced polymer brushes with composition dictated by the oxidation state of the complex. The electrically addressable surface formed by depositing catalyst-functionalized TiO2 nanoparticles on fluorine-doped tin oxide demonstrated spatial control in redox-switchable polymerization reactions and the potential for patterning surfaces with distinct polymer brushes featuring different physical properties.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
