Summary: This study identifies the reason for a 12-fold enhancement in oxygen evolution reaction (OER) activity by confining high-valence chromium into the lattice of pure cobalt oxyhydroxide. In-situ X-ray absorption spectroscopy reveals the formation of high-valence chromium with shortened Cr-O bond on the OER active site. Electrochemical impedance and infrared spectroscopy provide direct evidence of OOH* on the chromium site. The confined chromium is identified as the active site with improved bonding strength with O*, resulting in a lower overpotential than that on the cobalt site. This research elucidates the dynamic behavior of active sites and provides guidance for improving OER catalysts by introducing high-valence metals.

Summary: Understanding the synergistic mechanisms of bimetal single atom catalysts is crucial for designing and synthesizing effective catalytic materials. This study presents a novel bimetal of Fe and Ni anchored carbon nitride (CN-FeNi-P) and reveals the importance of synergistic effects. Experimental results show that CN-FeNi-P, with uniformly distributed Fe/Ni-N4P2 coordination sites, forms a Fe-P-Ni structure at the second shell via P bridging. The Fe-dominated active sites in CN-FeNi-P, resulting from the interaction between Fe and Ni single atoms, enable high efficiency electron utilization, leading to 100% enoxacin degradation and rare defluorination rate.

Summary: Based on density functional theory calculations, it was found that in transition metal- and nitrogen-codoped graphene, single Zn atoms do not serve as active sites for CO production in CO2 reduction reactions, while the nearest neighbor C atom (C-NN) exhibits high activity and the Zn atom enhances the catalytic activity of C-NN. The study also revealed that *COOH formation is favorable at the initial electrochemical step on the C-NN site, and each reaction step becomes downhill in energy at small applied potentials, elucidating the origin of the CO2 reduction activity.

Summary: In this study, low-cost Co-ZIF/CNF electrocatalysts with high OER and ORR performance were prepared using electrospinning and simple pyrolysis. The Co-ZIF/CNF catalysts contain both CoOx and Co-N-y active sites, exhibiting bifunctional activity for OER and ORR. The optimized catalyst Co-ZIF(1.5)/10CNF(2) shows outstanding OER and ORR catalytic performance with a low OER overpotential of 390 mV, an onset potential of 0.93 V, and a half-wave potential of 0.85 V for ORR. The catalyst also demonstrates great stability with 87.53% current retention after 12 hours. This study provides a new strategy for designing and preparing bifunctional catalysts for OER and ORR.

Summary: New insights into the catalytic mechanism of copper aluminate spinel catalysts were obtained through systematic studies on their structure and activity, with a focus on the effects of manganese as a catalyst component. Incorporation of manganese stabilizes the spinel structure towards reduction of copper, but also leads to decreased catalytic activity. The catalytic cycle involves a predominantly interface-based reaction mechanism, where protonation and reduction of aldehydes occur on both the spinel and copper nanoparticle surface.

Summary: Green fuel from water splitting is crucial for future generations, however, the limited source of fresh water is a bottleneck. The use of seawater as a feedstock in current electrolyzer techniques is not feasible. Recently, a cobalt single-atom based electrocatalyst was successfully synthesized using waste orange peel as a single feedstock. Experimental results showed that this catalyst exhibited 15 times higher oxygen evolution reaction activity compared to commercial RuO2. Theoretical interpretations suggest that the optimized cobalt single atoms reduce the energy barrier for alkaline water dissociation and trigger excellent oxygen evolution reactions.

Summary: In this study, a facile approach for decorating atomically dispersed Pt cocatalysts on CdS nanorods is reported. The PtSA+C/CdS photocatalysts exhibit optimized photocatalytic hydrogen evolution activity, achieving a reaction rate 1.6- and 7.3-fold higher than Pt-SA/CdS and Pt-NP/CdS photocatalysts, respectively. The synergy between single-atom and atomic cluster active sites is responsible for the enhanced photocatalytic activity.

Summary: Using density functional theory calculations, we identified the active sites for hydrogen evolution of single-atom Ni supported on TiO2, and found that the reactions mainly occur on SA Ni and its surrounding O atoms. The hydrogen evolution activity of Ni-1/TiO2 is roughly comparable to that of Pt, especially after hydrogen passivation, due to significant electron transfer from SA Ni to O-2(c) weakening the Ni-H and O-H bonds in the reaction. Free energy prediction and reaction simulation were consistent in identifying active sites and processes for hydrogen evolution, which can be combined for the rational design of SACs. Our work suggests that SACs based on metal oxides could potentially lead to the design of HER catalysts using transition metals instead of noble metals.

Summary: Improving the photo-catalytic performance of g-C3N4 by enhancing surface-active sites and optimizing redox couples is crucial. In this study, we synthesized porous g-C3N4 (PCN) through sulfuric acid-assisted chemical exfoliation and modified it with iron(III) meso-tetraphenylpor-phine chloride (FeTPPCl) via wet-chemical method. The resulting FeTPPCl-PCN composite demonstrated exceptional performance in photocatalytic water reduction with significantly improved hydrogen evolution rates compared to pristine PCN. This improvement can be attributed to the enhanced surface-active sites provided by the porous architecture and the well-aligned type-II band heterostructure for efficient charge carrier separation. Through density functional theory simulations, we confirmed the theoretical model of our catalyst and identified the role of electron transfer and electrostatic interactions in hydrogen evolution reaction (HER) activity. The FeTPPCl-PCN composite serves as a promising model for the development of high-efficiency heterostructure photocatalysts for energy applications.

Summary: Constructing multiple heterogeneous structures improves the electrocatalytic activity of NiO, but the poor conductivity of NiO hinders charge transfer. A new organic-inorganic hybrid method is used to fabricate F-doped NiO/Ni@C catalyst which exhibits superior hydrogen evolution and urea oxidation activity. The F-doping allows electron delocalization and facilitates electron transfer from Ni to NiO, resulting in optimized H* adsorption Gibbs free energy and reduced energy barrier. The F-NiO/Ni@C || F-NiO/Ni@C cell achieves 10 mA cm(-2) with an ultra-low cell voltage of 1.37 V, outperforming Pt/C|| RuO2 cell. This study highlights the positive impact of anion doping on interphase synergy and provides useful guidelines for designing monometallic catalysts for UOR and hydrogen generation.

Summary: In this study, an anodization technique was introduced to quickly construct Co-Mo-based bimetallic oxides with simplified process and reduced time and energy consumption. The prepared Co/CoO/Co2Mo3O8 exhibited enhanced HER performance compared to Co(OH)2/CoMoO4 and CoO/CoMoO4, showing low overpotential and high Tafel slope in 1 M KOH. The recovered Co/CoO/Co2Mo3O8 also demonstrated reproductive HER performance, indicating the high efficiency and sustainability of the proposed anodization strategy. These findings provide a new and efficient route to construct high-stable bi-metallic or multi-metallic oxides for large-scale energy conversion applications.

Summary: Doped carbon materials, especially F-doped carbon catalysts, have gained significant attention as metal-free catalysts for oxygen reduction reactions and as corrosion-resistant supports for Pt and non-Pt nanoparticles. F-doped carbon materials possess unique properties and greatly improve the activity and durability of the ORR compared to N-doped carbon materials. The high electronegativity of F-doping can efficiently modify the electronic band structure of carbon materials, favoring the ORR. This review systematically discusses the effect of F-doping/F co-doping on the electrocatalytic reduction of O2 in acidic and alkaline conditions, the stability and durability of fuel cell catalysts, and provides guidelines for working with F-doped carbons. Future research directions on F-doped carbons are also proposed to bridge the gap between laboratory-scale assessments and commercial applications.
