Biomass, though a major energy source, remains underutilized. Biochar from biomass pyrolysis, with its high porosity and surface area, is especially useful as catalyst support, enhancing catalytic activity reducing electron recombination in photocatalysis. Indonesia, the world’s top palm oil producer, generated around 12 million tons of empty fruit bunches (EFBs) 2023, making EFBs promising biochar source. This study synthesizes leftover EFB fibers at 500, 800, 1000 °C, analyzing structural changes via infrared Raman spectroscopy, along particle size area analysis, laying groundwork for future research. The smallest highest gained was 71.1 nm 10.6 × 102 m2/g. Spectroscopic analysis indicates that produced °C has nano-crystalline graphite crystallite approximately 5.47 nm. provides higher defect density, although lower conductivity. Other studies indicate our can be used support various green energy-related applications, i.e., counter electrodes, electrocatalysts, photocatalysts.

In-situ polymerization is an effective method for integrating co-catalysts homogeneously into the polymer matrix. Polyacrylonitrile (PAN)-derived highly graphitized carbon a state-of-the-art material with diverse applications, including materials energy storage devices, electrocatalysis, sensing, adsorption, and making structural composites of various technologies. Such can be effectively obtained through in-situ polymerization. The addition external catalysts during not only enhances rate but also facilitates degree graphitization quality graphitic upon at moderate temperatures. In this study, we apply technique to integrate aluminum triflate (Al(OTf)3) zirconocene dichloride (C5H5)2ZrCl2 co-catalyst boronated polyacrylonitrile (B-PAN) ensures uniform distribution without aggregation, facilitating formation well-ordered structure moderated temperature. Boronated solutions, (Al(OTf)3, or both) were prepared process, dried in oven, then subjected 1250 °C heating 1 min−1 h under N2 atmosphere. resulting was characterized determine impact on graphitization. This study provides valuable insights synthesizing high-quality materials, offering promising pathways their scalable production strategic use co-catalysis. These have potential applications fields, environmental technologies, storage, conversion, pathway design facile economical materials.
