Special Issue Information

Dear Colleagues,

Carbon-based materials are revolutionizing heterogeneous catalysis due to their exceptional tunability, sustainability, and diverse structural properties. Unlike traditional metal-based catalysts, carbon catalysts—including graphene, carbon quantum dots, and engineered nanocarbons, etc. —offer unique advantages such as high surface area, excellent electrical conductivity, and resistance to harsh conditions. These characteristics make them ideal for applications ranging from renewable energy conversion to environmental protection and green synthesis. The ability to precisely modify their surface chemistry through heteroatom doping or functionalization further enhances their catalytic performance and selectivity.

Recent breakthroughs in synthetic control, heteroatom doping, and defect engineering have significantly enhanced the catalytic performance of carbon materials, enabling activities rivaling or even surpassing conventional catalysts. However, challenges remain in understanding their reaction mechanisms, scaling up production, and achieving long-term stability under operational conditions. Original research articles, reviews, and perspectives on topics including but not limited to the following are welcome:

  • Design and synthesis of novel carbon catalysts;
  • Mechanistic studies and theoretical modeling;
  • Applications in electrocatalysis, photocatalysis, and thermal catalysis;
  • Sustainable processes and green chemistry;
  • Industrial applications and scalability.

If you would like to submit papers for publication in this Special Issue or have any questions, please contact the in-house Editor, Mr. Ives Liu (ives.liu@mdpi.com).

The high stability of chelated heavy metal complexes like Cu-EDTA renders their effective removal from industrial wastewater a persistent challenge for conventional treatment processes. This study developed a sustainable and high-performance CuO-modified biochar (CuO-BC) from corn straw waste for peroxydisulfate (PDS)-activated degradation of Cu-EDTA. Through systematic optimization, hydrothermal co-precipitation using copper acetate as the precursor followed by secondary pyrolysis at 350 °C was identified as the optimal synthesis strategy, yielding a dandelion-like structure with highly dispersed CuO on the BC surface. It achieved 93.8% decomplexation efficiency and 57.3% TOC removal within 120 min under optimized conditions, with an observed rate constant (Kobs) of 0.0220 min−1—five times higher than BC. Comprehensive characterization revealed that CuO-BC possessed a specific surface area and pore volume of 4.36 and 15.5 times those of BC, along with abundant oxygen-containing functional groups and well-exposed Cu–O active sites. The enhanced performance is attributed to the synergistic effects of hierarchical porosity facilitating mass transfer, uniform dispersion of CuO preventing aggregation, and surface functional groups promoting PDS activation. This work presents a green and scalable approach to transform agricultural waste into an efficient metal oxide-BC composite catalyst, offering dual benefits of environmental remediation and resource valorization.
