Summary: Nitrogen-doping three-dimensional hydrangea-like porous carbons (NHPCs) were prepared using coal tar pitch oxidized by KMnO4 (OCTP) as the carbon precursor and p-phenylenediamine (pPDA) as the nitrogen source. NHPCs exhibited a unique structure, large specific surface area, and high nitrogen content. As the electrode material for supercapacitors, NHPC-600 showed excellent electrochemical performance and cycle stability, achieving high energy density in different electrolytes.

Summary: Capacitive deionization (CDI) is a promising technology for salt removal from brackish water, and the performance relies on the electrode materials. This study investigated three ZIF-67-derived porous carbon nanomaterials and found that ZCNB exhibited the highest adsorption capacity due to its large specific surface area, good wettability, high surface charge, and suitable pore sizes. The presence of carbon nanotubes in other materials decreased their adsorption capacity.

Summary: This work presents a simple and fast method to synthesize a photocatalytic support based on a loofah sponge, which has a high capacity for photocatalytic discoloration of rhodamine B dye. The loofah sponge impregnated with Nb2O5 at lower temperatures (120 and 130 degrees C) showed complete discoloration of rhodamine B in a short time interval (20 min) in the photocatalytic process. The photocatalytic support stands out for its low cost, high performance, availability, and environmental friendliness.
