Abstract Designing effective electrocatalysts tailored for targeted reactions requires fundamental insights into the structure dependence of reaction microenvironment. Herein, inspired by finite element simulations, N,O co‐doped carbon nanosheets featuring a hierarchical micro/mesoporous to form an oxygen‐rich and local alkaline‐like microenvironment two‐electron oxygen reduction (2e − ORR) in neutral medium are designed. The situ ex test results confirmed that architecture can elevate pH accelerate generation intermediates (*O 2 , *OOH), leading high‐efficiency H O production. Utilizing this favorable microenvironment, N,O‐CNS 0.5 demonstrated exceptional electrosynthesis performance media, achieving superior yield rate (6705 mmol g catalyst −1 h flow cell). Additionally, comparative experiments density‐functional theory calculations provided confirmation bi‐doping N as active origin responsible electrochemical 2e ORR. This study synergistically manipulates sites, providing opportunity efficient electro‐production medium.

Abstract Ordered pore engineering that embeds uniform pores with periodic alignment in electrocatalysts opens up a new avenue for achieving further performance promotion. Hierarchically ordered porous metal–organic frameworks (HOP‐MOFs) possessing multilevel distribution are the promising precursors exploration of electrocatalysts, while scalable acquisition HOP‐MOFs editable components and adjustable size regimes is critical. This review presents recent progress on hierarchically MOF‐based materials enhanced electrocatalysis. The synthetic strategies different regimes, including self‐assembly guided by reticular chemistry, surfactant, nanoemulsion, nanocasting, first introduced. Then applications as exploring summarized, selecting representatives to highlight boosted performance. Especially, intensification molecule ion transport integrated optimized electron transfer site exposure over derivatives emphasized clarify directional integration effect endowed engineering. Finally, remaining scientific challenges an outlook this field proposed. It hoped will guide nanocatalysts boosting catalytic promoting practical applications.

Abstract As an ideal transition metal oxide, Co 3 O 4 is a P-type semiconductor with excellent electrical conductivity, non-toxicity and low cost. This work reports the successful construction of materials derived from metal-organic frameworks (MOFs) using surfactant micelle template-solvothermal method. The modified electrodes are investigated for their ability to electrochemically detect Pb 2+ Cu in aqueous environments. By adjusting mass ratios alkaline modifiers, morphological microstructures -X exhibit distinctive microspheres composed fiber stacks rods. results indicate that -1(NH F/CO(NH 2 ) = 1:0) has microsphere structure stacked fibers, unlike other two materials. -1/GCE used as active material electrode, it shows largest peak response currents , efficiently detects environment individually simultaneously. linear range simultaneous detection 0.5–1.5 μM, limits (LOD, S/N 3) 9.77 nM 14.97 nM, respectively. exhibits favorable electrochemical response, via -1 fibers. enhances number adsorption sites on material, thereby facilitating heavy ions (HMIs). presence oxygen vacancies (O V can also facilitate ions. electrode anti-interference ability, stability, repeatability. great practical significance detecting real water samples provides new approach developing high-performance oxide sensors MOFs.

Abstract Bacteria‐derived carbon anode materials have shown appealing potential for advanced energy storage applications due to their low cost and good sustainability. However, the few intrinsic defects, sluggish transmission dynamics, capacity become main bottleneck further development. Herein, study designs a highly B, N co‐doped mesoporous (BNMC)/staphylococcus aureus‐derived (SAC) composite via facile assembly route, followed by boron‐doping. Enabled heteroatom doping pore construction, resulting BNMC/SAC lithium‐ion batteries demonstrates high reversible of 621.77 mAh g −1 at 200 mA even after 500 cycles, an excellent rate performance 405.14 2 A . Importantly, in situ/ex situ characterizations theoretical simulation results unveil that co‐doping along with small amount P can significantly increase defects BNMC/SAC, thus providing more active sites storage. Furthermore, these structural features are conducive improving interfacial stability whole electrode, achieving thin uniform SEI film. The multi‐component strategy engineering presents scalable approach enhancing transfer dynamics carbon‐based electrode low‐cost
