23:T471,The electrochemical CO₂ reduction reaction (CO₂ RR) is a promising strategy for closing the carbon cycle. Increasing the current density ( J) for CO₂ RR products is a critical requirement for the social implementation of this technology. Herein, nanoscale tin-oxide-modified copper-oxide foam is hybridized with a carbon-based gas-diffusion electrode (GDE). Using the resultant electrode, the J_formate is increased to -1152 mA cm^-2 at -1.2 V versus RHE in 1 m KOH, which is the highest value for CO₂ -to-formate electrolysis. The formate faradaic efficiency (FE_formate ) reaches ≈99% at -0.6 V versus RHE. The achievement of ultra-high-rate formate production is attributable to the following factors: i) homogeneously-modified Sn atoms suppressing H₂ evolution and ii) the hydrophobic carbon nanoparticles on GDEs penetrating the macroporous structure of the foam causing the increase in the thickness of triple-phase interface. Additionally, the FE_formate remains at ≈70% under a high J of -1.0 A cm^-2 for more than 20 h.24:T4c0,Electrochemical energy conversion is an important strategy for addressing climate change and building a carbon‐neutral society. The use of inexpensive biomass resources to develop high‐performance catalytic materials that reduce the energy barrier of electrochemical reactions and minimize energy consumption has become a research hotspot for energy materials. Previous reviews have often categorized biomass‐derived catalysts by the biomass feedstocks used, but this classification method has major limitations because the roles of the same biomass material in different catalysts can vary. In this review, a new classification approach for biomass‐derived catalytic materials by focusing on the role of bio‐based materials in the overall catalyst system is proposed. The review is divided into three main sections, categorizing bio‐based materials by 1) the active components, 2) the carbon support, and 3) the entire catalyst. Additionally, a comprehensive summary is provided of catalytic materials at different scales, including the nanoscale, molecular scale, and single‐atom scale. It is hoped that this review will guide and inspire the future development of biomass‐derived electrocatalysts.25:T46b,We previously reported that the hydrolysis of Ir³⁺ in homogeneous solution could be triggered by irradiation with light whose energy was larger than a threshold value. In this work, we demonstrated that, by introducing Fe₂O₃ particles into solution, the incident light energy-restriction for the photo-catalyzed hydrolysis could be broken and the hydrolysis occurred at the Fe₂O₃/solution interface. The photo-generated holes on the Fe₂O₃ surface played a key role in oxidizing Ir(iii) to Ir(iv) species and triggered the deposition of IrO_x. We showed that this photo-catalyzed surface hydrolysis is a universal phenomenon that takes place on the surface of many n-type semiconductors such as Fe₂O₃, TiO₂, and Ag₃PO₄. As IrO_x is an efficient catalyst for oxygen evolution reaction, surface hydrolysis is a general, facile and efficient strategy to prepare semiconductor/IrO_x composites, which can be used as anodic materials for photoelectrochemical water splitting.
