Journal ArticleDOI
Activated carbon nanofibers derived from coconut shell charcoal for dye removal application
TL;DR: In this article, an electrospinning method with coconut shell charcoal (CSC) as carbon source and poly(vinyl alcohol) (PVA) as a spinning polymer agent was used for the activation of activated carbon nanofibers.
Journal ArticleDOI
Preparation of Activated Carbon from Alkali Lignin using Novel One-Step Process for High Electrochemical Performance Application
Mahardika Fahrudin Rois,Widiyastuti Widiyastuti,Heru Setyawan,Annie Mufyda Rahmatika,Takashi Ogi +4 more
TL;DR: In this paper, the porosity, morphology, crystallinity, specific electrocapacity, and Oxygen Reduction Reaction (ORR) electrocatalyst activity of Na-lignin via calcination at 700 °C were investigated.
Journal ArticleDOI
Carbonization of Lignin Extracted from Liquid Waste of Coconut Coir Delignification
TL;DR: In this paper, the utilization of lignin byproduct of the soda delignification process of coconut coir converted to the activated carbon by a simple precipitation method followed by the carbonization at various temperatures is presented.
Journal ArticleDOI
High-performance electrocatalyst made from lignosulfonate nanofiber composited with manganese dioxide without carbonation process
Mahardika Fahrudin Rois,Sella Ramadhani Alya Sasono,Widiyastuti Widiyastuti,Tantular Nurtono,Heru Setyawan +4 more
TL;DR: In this paper , a composite of Lignin-based electrospun nanofiber composited with MnO 2 mats is synthesized for support electrocatalyst applications, which is shown to have the best electrochemical properties with a current density of 1.5 mA/cm 2 and at potential applied of 0.4 V versus Ag/AgCl.
Journal ArticleDOI
Comparative study of single and bimetal-nitrogen-doped carbon prepared by polymerization and direct pyrolysis
Vuri Ayu Setyowati,Mahardika Fahrudin Rois,Widiyastuti Widiyastuti,Siti Nurkhamidah,Naili Saidatin,Mohammad Ficky Febrianto +5 more
TL;DR: In this paper , the effects of using transition metals and nitrogen-doped carbon obtained from the polymerization process are illustrated. But the pyrolysis method is chosen to optimize the role of each catalytic component such as metal precursors, nitrogen, and carbon source.
