Abstract

The synthesis of carbonaceous materials for reduced graphene oxide (rGO) precursors using oil palm empty fruit bunches waste as a carbon source offers a sustainable solution for waste management in the palm oil industry while delivering high-performance materials. The oil palm empty fruit bunches were carbonized, followed by acid washing, pyrolysis with ferrocene (8%, 12%, and 16% variations), and ultrasonication to produce rGO. The structural, electronic, and morphological properties of the rGO were analyzed using various characterization techniques. The band gap values decreased with increasing ferrocene concentration, from 1.14 eV (8%) to 1.06 (16%), indicating enhanced electronic conductivity. XRD analysis revealed a crystal size increase from 11.3 nm (8%) to 181 nm (16%), while Raman spectroscopy showed a consistent D to G intensity ratio of 0.85, indicating reduced structural defects. SEM-EDS results demonstrated a carbon to oxygen atomic ratio of 4.38 (8%), 3.79 (12%), and 3.77 (16%), confirming successful reduction and improved carbon content. These finding highlight the potential of rGO synthesized from oil palm empty fruit bunches for applications in semiconductors, energy storage, and gas sensing, offering an innovative approach to sustainable materials development.

Abstract

The production of graphene oxide (GO) from biomass presents considerable promise as a sustainable alternative substitute for traditional semiconductors. Biomass waste, abundant and often underutilized worldwide, is distinguished by its high carbon content and regenerative characteristics, rendering it an optimal resource for sustainable material production. By heating its biopolymers, lignocellulosic biomass can be used as a new material to make graphene, which forms three-dimensional turbostratic crystallites. These crystallites, composed of partially defective aromatic carbon sheets with graphite-like characteristics, make it easier to create GO with specialized functions for cutting-edge applications. Its capability underscores the revolutionary potential of biomass waste in producing high-value products from otherwise overlooked resources . A number of manufacturing methods are carefully studied and tested to improve the structure and oxygen functionality of GO. These include catalytic ferrocene, Hummer's, modified Hummer's, catalytic acid spray (CAS), Tour's, and electrochemical exfoliation. Additionally, doping with non-metallic elements, including nitrogen, boron, sulfur, and phosphorus (e.g., N, B, S, P), is investigated to adjust the band gap and improve charge carrier mobility, all of which are essential for optimizing electro-optical performance in semiconductors. This study highlights the unexploited potential of biomass as a resource and establishes a foundation for the advancement of GO-based semiconductors, driving the development of more environmentally friendly, efficient, and sustainable electronic technology.

Abstract

This study investigates the potential of ceramic membranes derived from areca nut fiber as a cost-effective and environmentally sustainable material for the removal of iron (Fe) and manganese (Mn) from groundwater. Two types of membranes were fabricated: one without activation and one chemically activated using 10% sodium hydroxide (NaOH). The morphological and elemental characteristics of both membranes were analyzed using Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDX) mapping. The concentrations of Fe and Mn before and after treatment were measured using Atomic Absorption Spectroscopy (AAS). The NaOH-activated membrane exhibited a more porous surface structure and higher oxygen content, which enhanced its adsorption capability. This membrane achieved removal efficiencies of 55.94% for Fe and 67.72% for Mn- substantially higher than the non-activated variant. The results confirm the effectiveness of NaOH activation in enhancing membrane performance and demonstrate the potential of areca nut fiber as a valuable agricultural waste material for low-cost water purification in rural areas.
