Over the last decade, carbon-based metal-free electrocatalysts (C-MFECs) have become important in electrocatalysis. This field is started thanks to initial discovery that nitrogen atom doped carbon can function as a electrode alkaline fuel cells. A wide variety of nanomaterials, including 0D dots, 1D nanotubes, 2D graphene, and 3D porous carbons, has demonstrated high electrocatalytic performance across applications. These include clean energy generation storage, green chemistry, environmental remediation. The applicability C-MFECs facilitated by effective synthetic approaches, e.g., heteroatom doping, physical/chemical modification. methods enable creation catalysts with properties useful for sustainable transformation storage (e.g., cells, Zn-air batteries, Li-O

Abstract The electrochemical activation of inert CO 2 molecules through C─C coupling reactions under ambient conditions remains a significant challenge but holds great promise for sustainable development and the reduction emission. Lewis pairs can capture react with , offering novel strategy electrosynthesis high‐value‐added C2 products. Herein, an electron‐beam irradiation is presented rapidly synthesizing metal–organic framework (MOF) well‐defined (i.e., Cu‐ N pyridinic ). synthesized MOFs exhibit total product faradic efficiency 70.0% at −0.88 V versus RHE. In situ attenuated reflection Fourier transform infrared Raman spectra reveal that electron‐deficient acidic Cu sites electron‐rich basic in ligand facilitate targeted chemisorption, activation, conversion molecules. DFT calculations further elucidate electronic interactions key intermediates reaction. work not only advances pair‐site as new platform conversion, also provides pioneering insights into underlying mechanisms irradiated synthesis advanced nanomaterials.

Abstract Electroreduction of carbon dioxide (CO 2 ) is a key strategy for achieving net‐zero emissions. Copper (Cu)‐based electrocatalysts have shown promise CO conversion into valuable chemicals but are hindered by limited C 2+ product selectivity due to competing hydrogen evolution and ineffective dimerization adsorbed intermediate ( * CO). Here, functional‐group‐directed reported enhance using single‐walled nanotubes (SWCNTs) as supports. The catalytic performance Cu nanoparticles strongly influenced the type density functional groups on SWCNTs. Optimized Cu/amine‐functionalized SWCNTs achieved Faradaic efficiency 66.2% partial current −270 mA cm −2 products within flow cell, outperforming Cu/SWCNTs Cu/cyano‐functionalized Density theory calculations revealed that electron‐donating amine can facilitate electron transfer from graphite sheet atoms, thereby shifting d‐band center upward. This shift enhances its hydrogenation derivative adsorption promotes water splitting, leading an increased tendency generation products. In situ infrared Raman spectroscopy confirm enhancement CHO coverage, facilitating C─C coupling. work provides molecular framework exploring interactions between active metals in electrolysis, offering insights designing catalysts broad range electrocatalytic processes.

Abstract Natural biomass-derived carbon material is one promising alternative to traditional graphene-based catalyst for oxygen electrocatalysis. However, their electrocatalytic performance were constrained by the limited modulating strategy. Herein, using N-doped commercial coconut shell-derived activated (AC) as model, controllably enhanced sp 2 -C domains, through an flash Joule heating process, effectively improve edge defect density and overall graphitization degree of AC catalyst, which tunes electronic structure N configurations accelerates electron transfer, leading excellent reduction reaction (half-wave potential 0.884 V RHE , equivalent 20% Pt/C, with a higher kinetic current 5.88 mA cm −2 ) evolution activity (overpotential 295 mV at 10 ). In Zn-air battery, shows outstanding cycle stability (over 1200 h) peak power 121 mW surpassing Pt/C RuO catalysts. Density functional theory simulation reveals that catalytic arises from axial regulation local domains. This work establishes robust strategy domain modulation, offering broad applicability in natural biomass-based catalysts
