Photocatalytic synthesis based on the oxygen reduction reaction (ORR) has shown great promise for H2O2 production. However, low activity and selectivity of 2e– ORR result in a fairly efficiency Herein, we propose strategy to enhance proton-coupled electron transfer (PCET) process covalent organic frameworks (COFs), thereby significantly boosting photosynthesis. We demonstrated that construction hydrogen-bonding network, achieved by anchoring H3PO4 molecular network COF nanochannels, can greatly improve both proton conductivity photogenerated charge separation COFs. Thus, COF@H3PO4 exhibited superior photocatalytic performance generating without sacrificial agents, with solar-to-chemical conversion as high 0.69%. Results indicated much more localized spatial distribution energy band density led efficient separation, small barrier rate-limiting step from *OOH endowed higher selectivity.

ABSTRACT Ruthenium (Ru)‐based electrocatalysts show great promise as substitutes for platinum (Pt) the alkaline hydrogen evolution reaction (HER) because of their efficient water dissociation capabilities. Nevertheless, strong adsorption Ru–OH intermediates (Ru‐OH ad ) blocks active site, leading to unsatisfactory HER performance. In this study, we report a universal ligand‐exchange strategy synthesizing MOF‐on‐MOF‐derived FeP–CoP heterostructure‐anchored Ru single‐atom site catalyst (Ru‐FeP‐CoP/NPC). The obtained shows low overpotential (28 mV at 10 mA cm −2 and high mass activity (9.29 A mg −1 100 mV), surpassing performance commercial Pt/C by factor 46. Theoretical studies that regulating local charge distribution sites could alleviate surrounding OH − blockages, accelerating facilitating adsorption/desorption, thus enhancing activity. This work aims inspire further design highly durable with tailored electronic properties high‐purity production.

Breaking the activity-selectivity trade-off has been a long-standing challenge in catalysis. Here, we proposed nanoheterostructure engineering strategy to overcome metal phosphide catalysts for oxidative desulfurization (ODS) of fuels.

Abstract Heterogeneous interfaces designed rationally in catalysts can induce geometrical, compositional, and electronic effects that be applied to modulate catalytically active sites consequently accelerate reaction kinetics. Here, a core‐shell heterostructure catalyst consisting of crystalline molybdenum phosphide (MoP) cores amorphous tungsten oxide (WO x ) shells on porous carbon nanosheets (PCN) is developed for oxidative desulfurization (ODS) fuels. The strongly coupled heterogeneous interface triggers distinctive atomic permeation effect induces substantial electron transfer from MoP WO subsequent generation electron‐rich W sites, optimizing the adsorption intermediates substrates. resulting @MoP/PCN) demonstrates turnover frequency as high 768.1 h −1 ODS at 60 °C, exceeding almost all state‐of‐the‐art by 1–2 orders magnitude. Moreover, novel surface oxidation pathway based direct identified @MoP/PCN‐H 2 O system, which bypasses formation reactive oxygen species, endowing system with moderate redox potential. Thus, @MoP/PCN exhibits unprecedented selectivity, achieving 100% removal thiophenic sulfides real diesel minimal consumption oxidant.
