Article Abstract

Substituent-modulation induced electronic perturbations can fine-tune the charge cloud distribution around carbon defects. The transfer of electrons from electron-donating substituents to carbon defects will lead to lower p band center of carbon atoms, stronger C-O bonds, narrower band gaps, and asymmetric orbital distribution, consequently enhancing the ORR thermodynamic activity and kinetic efficiency.

Interdisciplinary Research Center for Hydrogen Technologies and Carbon Management (IRC-HTCM), King Fahd University of Petroleum & Minerals, KFUPM Box 5040, Dhahran, 31261, Saudi Arabia.

The synthesis of biomass-derived nanocarbons via ball milling has emerged as an innovative, sustainable, and cost-effective strategy in the field of nanotechnology. This review comprehensively explores the principles, mechanisms, and process parameters that influence the production of high-quality nanocarbons from biomass using ball milling. This process efficiently transforms biomass residues into nanoscale carbon, including graphene, carbon nanotubes, and nanofibers, with tunable physicochemical properties tailored for advanced applications.

To contribute to the circular and sustainable economy framework, waste tire rubber reclamation by extracting carbon black through pyrolysis and heat treatment and then ingeniously designing it as an electromagnetic wave absorbing (EWA) material is proposed herein. The results showed that the pyrolysis-recycled carbon black (RCB) was heterogeneous with multiple interfaces, making it suitable for EWA application. The RCB was processed at 500 °C-1000 °C to study the changes in the composite and microstructure as well as the EWA properties.

Overcoming the persistent challenges of high operating temperatures and poor selectivity in metal oxide semiconductor (MOS) gas sensors, this work enhances defect sites in the sensing material through heterostructure construction and builds mesoporous architectures using MOF-derived carbon skeletons as templates. The synergistic effects of multiple mechanisms significantly improve gas-sensing performance, successfully fabricating a ZnO/PCS flexible room-temperature gas sensor with exceptional room-temperature DMF detection capabilities. The nitrogen-containing porous carbon skeletons (PCSs) template shows a stable mesoporous microstructure with large pore volume.

This study explores the role of α-Fe₂O₃ in improving extracellular electron transfer (EET) and symbiotic interactions between electroactive Shewanella oneidensis MR-1, its gene-deficient mutants (ΔmtrC, ΔomcA, and ΔcymA), and microalgae (Chlorella vulgaris). The iron oxide facilitates the efficient transfer of electrons generated by MR-1 to microalgal photosystem via the pathway of CymA-MtrC-OmcA to α-Fe₂O₃. This process enhances the removals of TOC, TN, and NH₄⁺-N in the MR-1 bacterial-algal consortium by 9.
