High-performance devices require porous carbon electrodes with controlled intraparticle properties - such as morphology, size, porosity, elemental composition, and graphitic microstructure - and interparticle features like electrode-level porosity, percolation pathways, and tortuosity, that influence mass transport. Here, mesoporous N-doped carbon (MPNC) nanospheres with independently tunable particle size at a fixed pore size is reported. Extending the previously established synthesis toolbox, independent control over particle and pore sizes is demonstrated. Using a 9 nm SiO₂ hard template, particle sizes between 50 and 300 nm is adjusted while maintaining comparablSmall (Weinheim an der Bergstrasse, Germany)Pore Size Independent Particle Size Control of Mesoporous N-doped Carbon Nanospheres for 3D Bottom-Up Electrode Design.PMC1275799203SF0614AEXC-2193/1-390951807Ortlieb NAmin HMNFischer ACamarada MBBalaghi SEBasu OfalsePore Size Independent Particle Size Control of Mesoporous N-doped Carbon Nanospheres for 3D Bottom-Up Electrode Design.The rational design of electrodes is crucial for improving electrochemical energy storage and conversion devices.
