Abstract Electrocatalytic N 2 oxidation reaction (NOR) is an environmentally sustainable approach to synthesize NO 3 − under mild conditions. Inspired by the ferriporphyrin (FePP) catalytic species in nitrite oxidoreductase, three FePP‐based biomimetic catalysts with different functional groups (─NH , ─H, and ─COOCH ) are designed prepared successfully. Theoretical calculations indicate that these can alter electron density of Fe center, affecting their ability adsorb activate . The strong electron‐donating ─NH group enhance iron sites, which reveals a maximum yield 728.55 µmol h −1 g FePP high Faradaic efficiency 10.6%. After that, optimized molecules be encapsulated into ZIF‐8, remarkably promoted ─to─NO transformation production rate 1767.74 achieving highest effect among metalloporphyrin‐based molecular This work develops available modulate distribution active metal sites confine porous crystalline materials for constructing high‐performance NOR electrocatalysts.

Introduction: Enhancing the photoelectrochemical response of TiO2 nanotube arrays (TNA) is crucial to improve efficiency solar energy utilization. In this work, TNA was prepared electrochemically by anodization at single voltages 20 V, 30 V and 40 as well a special two-step voltage V-20 V-40 respectively. X-ray diffraction (XRD) scanning electron microscopy (SEM) were used characterize morphology crystalline structure sample. Methods: The measured electrochemical potentiostatic technique. results show evenly aligns with increasing voltage. Results: However, there that does not form dispersed fragments on surface higher voltage, which adversely affects TNA’s properties. Conclusion: During process anodization, oxidation current changes due switch in A method enhances pure TNA's visible light.
