Liquid‐Mediated Kinetically Controlled Synthesis of Porous Carbon with Homogeneous Graphitic Networks for High‐Rate and High‐Loading Organic Supercapacitor

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Liquid‐mediated kinetic control reconstructs a “rigid–flexible” carbon precursor into homogeneously graphitized porous carbon. The resulting porous structure and homogeneous graphitic network accelerate ion/electron transport, enabling superior performance in high‐rate and high‐loading organic supercapacitors.

Catalytic Pyrolysis of Torrefied Municipal Solid Waste Using Local Iron for Improved Bio‐Oil Yield and Energy Efficiency

Energy Science &Engineering, EarlyView.
Catalytic Pyrolysis of Torrefied Municipal Solid Waste to sustainable bio‐oil. ABSTRACT South Africa faces growing municipal solid waste (MSW) accumulation and energy insecurity due to fossil fuel dependence. Torrefaction improves MSW for waste‐to‐energy use, while conventional pyrolysis produces low‐quality oxygen‐rich bio‐oil.
