The urea oxidation reaction (UOR), requiring less energy to produce hydrogen, is considered as a potential alternative the traditional oxygen evolution reaction. Consequently, developing highly efficient UOR catalysts facilitate H2 production has garnered widespread attention. A promising approach enhancing effectiveness of these electrocatalysts defect engineering. By introducing structural defects, engineering can expose more active sites and optimize their electronic structure, thereby improving activity. This work offers comprehensive overview recent progress in nickel-based for UOR. It summarizes various strategies generating including creation vacancies, doping, incorporation single atoms, amorphization, achieving high refractivity. Furthermore, we discuss advanced characterization techniques commonly used identify presence defects electrocatalysts, well determine detailed structures. Finally, outline prospects challenges associated with systematic design fabrication novel tunable aiming further enhance efficiency stability.

Molecular doping is an innovative approach to modify the electronic configuration of carbon nitride (CN) photocatalysts, enhancing visible light absorption and optimizing recombination electron–hole pairs in photocatalytic H2 generation. Unlike conventional heteroatom incorporation strategy, molecular offers a more effective means structure optimization conjugated framework. This Perspective studies recent advancements benzene-ring for CN, emphasizing correlation between activity. The advantages disadvantages CN are thoroughly demonstrated, underscoring importance utilizing fine-tune both physical structures enhanced efficacy. Insights provided on strategies address limitations explore new prospects field methodologies.

Piezo-photocatalytic efficiency is severely constrained by the wide band gap and bad piezoelectric properties. Herein, La(Mn0.5Ni0.5)O3 was successfully introduced into NaNbO3 lattices (referred to as 0LMN, 0.05LMN, 0.10LMN, 0.15LMN) through a water-based sol–gel method. The piezo-photocatalytic degradation ratio for Rhodamine B (RhB) enhanced from 59.7% (0LMN) 89.7% (0.10LMN) within 100 min, kinetic rate constant (k) increased 0.009 0.022 min–1. performance attributed (i) narrowed (from 3.40 2.84 eV), which conducive generation of photogenerated electrons holes, (ii) properties, can strengthen polarization, thereby accelerating separation holes. And we also found that synergetic effect photocatalysis piezocatalysis superior alone. This study could provide new perspectives reasonable construction an efficient catalyst in field.
