Abstract

This study aimed to synthesize materials from the carbon biomass of sunflower seed husk (Helianthus Annuus) for sodium ion battery anode. A simple carbonization process was carried out by roasting. The chemical activation process was conducted by adding KOH as much as 4M in 100 mL water solution for 20 hours. Then drying was done in the oven at a temperature of 100ºC for 20 hours, and then continued with the sintering process at a temperature of 900ºC for 2 hours. The sintered results were washed and hydrothermal for 20 hours at 200ºC with 4 mL H2O2 and 1 mL EG in 50 mL Teflon. The resulting acid degree was neutralized (pH ~ 7) with distilled water and then dried at 100ºC for 20 hours. The hydrothermal powder was pulverized using a mortar and pestle and then sieved on a 325 mesh sieve. Anode sheets were prepared by mixing active ingredients: PVDF: Super-P with a composition of 85: 10: 5 by adding 2 ml of DMAC solvent. Electrochemical characterization testing was carried out to see the resulting performance—the results obtained from EIS, CV, and CD show that commercial hard carbon is better.

Abstract

Organic pollutants, including pesticides and industrial waste, have become a significant environmental challenge due to their persistence and difficulty in decomposition, posing serious threats to both environmental health and water quality. This issue is particularly pressing in regions like Penang, where rapid industrial development and urbanization have exacerbated water pollution. In response, various research efforts have explored potential solutions, with graphite emerging as an effective adsorbent for removing toxic compounds from water. Building on this, our study focuses on the synthesis of graphitic carbon nitride (g-C3N4), a material recognized for its high-performance photocatalytic properties. g-C3N4's unique structure and ability to harness solar energy make it a promising candidate for catalyzing the breakdown of organic pollutants into less harmful molecules. Our project aims to develop a cost-effective and scalable method for producing g-C3N4 using readily available materials, with the goal of mitigating organic pollution in Penang. Through a straightforward synthesis process, we seek to make this technology accessible for widespread adoption in water treatment practices. The successful synthesis of g-C3N4 has already been demonstrated, with the process being effectively shared with students from the School of Chemical Science at USM. While further refinements are needed to maximize results, our findings suggest that g-C3N4 can play a crucial role in reducing organic pollution and improving water quality, contributing to the long-term sustainability of Penang's environment.
