Porous heterostructure of h-BN/carbon as an efficient electrocatalyst for hydrogen peroxide generation
Carbon Letters - - 2024
Xiang Xu, Yuying Zhao, Qixin Yuan, Yuhan Wu, Jiawei He, Mengmeng Fan
We successfully synthesized a porous carbon material with abundant hexagonal boron nitride (h-BN) dispersed on a carbon matrix (p-BN-C) as efficient electrocatalysts for two-electron oxygen reduction reaction (2e− ORR) to produce hydrogen peroxide (H2O2). This catalyst was fabricated via ball-milling-assisted h-BN exfoliation and subsequent growth of carbon structure. In alkaline solutions, the h-...... hiện toàn bộ
Effects of multi-walled carbon nanotube and flow types on the electrical conductivity of polycarbonate/carbon nanotube nanocomposites
Carbon Letters - Tập 29 - Trang 57-63 - 2019
Kwan Han Yoon, Young Sil Lee
Effects of multi-walled carbon nanotube (MWCNT) type and flow type (shear and elongational flow) on the electrical conductivity of polycarbonate (PC)/MWCNT nanocomposites were investigated. Two different MWCNTs produced a huge difference in electrical conductivity in an injection molded PC/MWCNT nanocomposite. It was observed that MWCNTs having a higher aspect ratio provide much lower electrical c...... hiện toàn bộ
C/SiO2 and C/SiC composite foam monoliths from rice husk for thermal insulation and EMI shielding
Carbon Letters - Tập 32 - Trang 639-651 - 2021
A. Chithra, R. Rajeev, K. Prabhakaran
Preparation of advanced functional materials from agricultural waste by eco-friendly processing route is inevitable for sustainable development. This work demonstrates the development of carbon/silica (C/SiO2) and carbon/silicon carbide (C/SiC) composite foam monoliths of low thermal conductivity, high EMI shielding performance and reasonable compressive strength from rice husk. The C/SiO2 and C/S...... hiện toàn bộ

Study of a melt processable polymer precursor for carbon fiber
Carbon Letters - Tập 29 - Trang 605-612 - 2019
Samsuddin F. Mahmood, Benjamin L. Batchelor, Minhye Jung, Kyusoon Park, Walter E. Voit, Bruce M. Novak, Duck Yang
Carbon fibers (CF) are predominantly being manufactured from polyacrylonitrile (PAN) based precursors which require solution spinning utilizing health hazardous organic solvent. This also adds to the cost of production due to the investment for the solvent recovery. Study of melt processable precursors has long been sought as a solution for health and environmental problems associated with the use...... hiện toàn bộ
Black phosphorus nanosheets-based effective electrochemical sensor for uric acid detection
Carbon Letters - Tập 33 - Trang 2161-2169 - 2023
Hao Wang, Haitao Wang, Jingjing Yang, Pramitha Yuniar Diah Maulida, Jing Zou, Arramel, Can Wu, Jizhou Jiang
Black phosphorus (BP) is incorporated in the electrochemical detection of uric acid (UA) to form few layers of BP nanosheets (BPNS)-modified glassy carbon electrodes (BPNS/GCE), investigated by means of ultrasound-assisted liquid-phase exfoliation. We find a significant increase in the peak current magnitude and positive potential shift in the electrochemical response of BPNS/GCE, which may be att...... hiện toàn bộ
Microporous-activated carbons of type I adsorption isotherm derived from sugarcane bagasse impregnated with zinc chloride
Carbon Letters - Tập 32 - Trang 229-249 - 2021
Ahmed El Nemr, Rawan M. Aboughaly, Amany El Sikaily, Mamdouh S. Masoud, Mohamed S. Ramadan, Safaa Ragab
Sugarcane bagasse has been used as a substrate for the development of microporous nano-activated carbons for the treatment and elimination of dissolved materials from aquatic environment. The activated carbon was produced using chemical activation in one-step method with zinc chloride (ZnCl2) as the activating agent at a carbonization temperatures range from 500 to 900 °C. The effects of temperatu...... hiện toàn bộ
Mechanical and microstructural properties of ultrafine slag cement mortar reinforced with graphene oxide nanosheets
Carbon Letters - Tập 33 - Trang 1649-1660 - 2023
T. Yeswanth Sai, P. Jagadeesh
Graphene oxide (GO) and ultrafine slag (UFS) have been applied to reinforce cement mortar cubes (CMC) in this research. The consequences of GO and UFS on the mechanical attributes of the CMC were explored through experimental investigations. Established on the results, at the 28 days of hydration, the CMC compressive and flexural strength with 0.03% of GO and 10% UFS were 89.8 N/mm2 and 9.1 N/mm2,...... hiện toàn bộ
