Electrocatalytic urea oxidation reaction(UOR)not only provides innovative solutions for clean energy development and environmental pollution control,but also promotes sustainable development through efficient resource recycling.Its technological breakthroughs hold significant implications for achieving carbon neutrality goals and establishing a green energy system.Benefiting from their high specific surface area,tunable pore structures,and modifiable electronic properties,diverse metal–organic frameworks(MOFs)-based UOR electrocatalysts have been exploited,such as pristine Ni-,Fe-,and Cu-based monometallic,bimetallic,or multiple metallic MOFs,MOFs-based composites,and MOFsrelated derivatives.The porous framework exposes abundant active sites and enhances mass transfer,while the synergy between metal nodes and organic ligands optimizes electronic configurations to reduce reaction energy barriers.By integrating conductive substrates or constructing heterostructures,catalytic activity and stability are significantly enhanced.Varieties of strategies have been performed to further decrease the overpotential and accelerate the kinetics towards the UOR,such as modulating charge density and d-band center positions of active sites through metal–ligand coordination,inducing charge redistribution and enhancing electron transport via heterostructure interfaces,breaking electronic symmetry and boosting surface reactivity through defect engineering,adjusting atomic spacing and electronic band structures via strain engineering,reinforcing charge transfer and stabilizing active sites using conductive substrates,and enabling precise design through dynamic in-situ reconstruction and theory-guided optimization.This review explores the latest significant advances in the design and synthesis of MOFs-based UOR catalysts.Beyond highlighting recent breakthroughs in UOR catalysts,this review critically emphasizes the design strategies for urea electrolysis in the field of energy conversion and systematically addresses current challenges.Furthermore,this comprehensive research approach proposes forward-looking strategies for future research directions in energy conversion and carbon neutrality to advance the development of this emerging field. 展开更多

The characteristic of green detergents and it＇s difference with regular detergent was expounded in this paper, according to the kernel of green chemistry. The variation trends of Chinese mainstream consumer group show that the new mainstream consumer group are concerning more and more about household detergent, especially its safety to human and environment. Growing attention of the mainstream consumer group and the standard drafting units on detergent will promote the development of green detergents, however, there are still challenges for the development of green detergents. 展开更多
