Summary: In this study, non-supported pure and mixed cobalt and iron oxide catalysts were synthesized using a simple, environmentally friendly preparation method in which water was the sole solvent. The results showed that the mixed oxide catalysts exhibit higher catalytic activity than the pure oxides, and the Fe: Co atomic ratio is the key factor in the catalytic activity of these mixed oxides. Among the catalysts tested, the 50Fe + 50Co catalyst showed the highest catalytic activity towards methane conversion, reaching about 52.6%.

Summary: The study demonstrates the synthesis of forest-like ZIF-8-based material using a metal template-guided growth approach. The resulting ZIF-8 forests with a 3D self-supported array architecture exhibit efficient exposure of active sites, rapid mass transfer, and simple recovery. The catalytic activity of the ZIF-8 forests towards the coupling of epoxides and CO2 is remarkable, with a cyclic carbonate yield of 96%. Importantly, the catalytic performance is well-maintained even after multiple cycles and under various conditions.

Summary: Hybrid water electrolysis has been explored for the electrochemical oxidation of biomass, glucose, alcohols, amines, urea, etc. to produce value-added products. The integration of cathodic hydrogen evolution reaction (HER) with anodic organic reaction (AOR) improves the energy efficiency of the electrolyzer by reducing the cell voltage of the overall process. The atomic and electronic structure of M(O)(x)(OH)(y) essentially controls the conversion efficiency and product selectivity for AOR.

Summary: A hydrogen processing strategy is developed to improve the performance of LaNi5 as an electrocatalyst for the oxygen evolution reaction (OER). The surface of LaNi5 is reconstructed into a porous hetero-nanoarchitecture composed of gamma-NiOOH nanocrystals, which optimizes the charge transfer and structural integrity. The hydrogen-processed OER catalyst shows a significantly reduced overpotential and remarkable stability in alkaline media, making it a promising candidate for industrial applications.

Summary: The appropriate choice of an electrocatalyst is crucial for controlling the selectivity of electrocatalytic CO2 reduction products. This study explores the effect of different ligand environments on 2D metal-organic frameworks (MOFs), namely copper naphthalenedicarboxylate (Cu-UNDC) and copper benzenedicarboxylate (Cu-UBDC). The change in ligand modulates the structure of the MOFs as well as the electronic environment around the copper center, resulting in altered selectivity towards C-2 products. Cu-UNDC exhibits a significantly higher Faradaic efficiency (FE) of 24.3% for C-2 products in the electrocatalytic process compared to Cu-UBDC (13.2%). However, under light irradiation, Cu-UBDC achieves a higher FE of 26.2% for C-2 products compared to Cu-UNDC (21.8%) in contrast to electrocatalytic CO2 reduction.

Summary: In this study, a facile method for synthesizing CeO2/Ce-Co-LDH heterostructures has been demonstrated. The incorporation of Ce in Co-LDH leads to orbital overlap and adjustment of the electronic structure, while the oxygen-deficient CeO2 controls the charge transfer at the interface. This results in excellent water oxidation activity.
