Summary: This study presents a simple approach to construct a two-dimensional hollow carbon skeleton decorated with ultrafine Co3O4 nanoparticles. The composite, derived from a leaf-like zeolitic imidazolate framework-L (ZIF-L (Co)) via etching coordination using tannic acid (TA), possesses a unique structure consisting of a 2D carbon skeleton, ultrafine Co3O4 nanoparticles, and open channels. This structure enables enhanced electron transport, alleviated volume change, and facilitated ion diffusion, leading to superior reversible cycle performance and impressive rate property of the lithium-ion batteries assembled using this composite as the anode material. This research provides an efficient strategy for implementing transition metal oxide-based composites in energy storage applications.

Summary: This paper summarizes the preparation process and structural characteristics of various supported catalysts, including graphite, metal-organic frameworks (MOFs), metal oxides, carbon nitride (CN), molybdenum carbide (MoC), carbon nanotubes (CNTs), boron nitride (h-BN), zeolites, carbon dots (CDs), and metal carbide and nitride (MXene). In addition, the relationship between the electronic structure and catalytic performance is discussed to determine the actual active sites in the catalytic process. The mechanism of AB hydrolysis catalysis is systematically discussed, and possible catalytic paths are summarized to provide theoretical considerations for the designing of efficient AB hydrolysis catalysts. Furthermore, three methods for stimulating AB from dehydrogenation by-products and the design of possible hydrogen product-regeneration systems are summarized. Finally, the remaining challenges and future research directions for the effective development of AB catalysts are discussed.

Summary: In this study, a heterointerface was constructed by modifying CeO2 nanoparticles on Co3O4 nanowires supported by nickel foam, which facilitated the structural evolution of catalysts and charge transfer. The NF@Co3O4/CeO2 exhibited higher conversion, yield, and efficiency compared to NF@Co3O4 and NF@CeO2 due to the establishment of the heterointerface. Density-functional theory calculations showed that the heterointerface effectively regulated intermediate adsorption and promoted electron transfer, leading to improved performance of electocatalytic 5-hydroxymethylfurfural oxidation reaction (HMFOR).

Summary: Hydrogen (H2) is receiving considerable attention due to its high gravimetric capacity density and environmentally friendly nature. The steam reforming of natural gas is the current main method for hydrogen production, resulting in significant greenhouse gas emissions. Recently, the hydrolysis of diboranes has shown promise for H2 evolution, as both hydrogen atoms in the released H2 are obtained from water. This review provides an overview of recent developments in the mechanism study and applications of H2 evolution through diborane hydrolysis, and suggests future research focus and perspectives for commercialization.

Summary: The bimodal oxygen vacancy (V-O) catalysis strategy significantly enhances water dissociation on Pt nanoparticles, leading to the highest catalytic activity among Pt-based materials in ammonia borane hydrolysis. Theoretical simulation and characterization analyses reveal that the bimodal V-O promotes water dissociation in two ways: through an ensemble-inducing effect of Pt and V-O in TiO2, and through an electron promoter effect induced by electron transfer from V-O in NiOx to Pt. This insight establishes a new avenue for designing heterogeneous catalytic materials in the field of energy chemistry.
