One-step synthesis of 2D–2D Co(OH)2–MoSe2 hybrid nanosheets as an efficient electrode material for high-performance asymmetric supercapacitor

Synergistic 2D MoSe2@WSe2 nanohybrid heterostructure toward superior hydrogen evolution and flexible supercapacitor

“…The strong predominant peaks at 13.76°and 13.67°are produced by WSe 2 and MoSe 2 , which can be assigned to the (002) lattice plane. 29,30 All other peaks are well indexed with no impurity peak, which confirmed the polycrystalline nature and monohexagonal phase of the as-prepared MoSe 2 and WSe 2 nanocrystals thin films (JCPDS# 29-0914 & JCPDS#38-1388). The broadening and weak intensity of the peaks indicates the nanocrystalline nature of exfoliated MoSe 2 and WSe 2 .…”

Fabrication of Enzyme-Free and Rapid Electrochemical Detection of Glucose Sensor Based on ZnO Rod and Ru Doped Carbon Nitride Modified Gold Transducer

“…Figure S6 of the Supplementary Materials shows the effect of the scan rate varied from 10 to 100 mV s −1 in the presence of 1 mM glucose in PBS. From the result, the scan rate is increased and the glucose oxidation peak current also increases, due to its diffusion-controlled (1.75 × 10 −6 cm −1 ) oxidation of glucose to gluconolactone [ 35 , 36 , 37 , 38 , 39 , 40 ]. Next, the effect of the pH on the ZnO–g–Ru–C 3 N 4 modified electrode in the presences of 1 mM glucose oxidation peak current and peak potential was carefully monitored by CV using 100 mM PBS in different pH ranging (5, 5.5, 6, 7, 7.4, 8 and 8.5) at a scan rate 50 mV s −1 in Figure 4 .…”

Development of 3D-Printed MWCNTs/AC/BNNTs Ternary Composite Electrode Material with High-Capacitance Performance

“…The MWCNTs/AC/BNNTs-3 composite has shown a lengthy charging-discharging cycle at a minimum current density of 1 A g −1 , while the charging-discharging cycle lengths were decreased as the current density was increased from 1 to 10 A g −1 . The specific capacitance of the MWCNTs/AC/BNNTs-3 composite electrode material was calculated from the measured GCD plots according to Equation (1). The MWCNTs/AC/BNNTs-3 composite has shown a maximum specific capacitance of 262 F g −1 at 1 A g −1 with 49.61% capacitance retention at a maximum current density of 10 A g −1 .…”

“…Over the past few decades, the depletion of fossil fuels and a significant increase in energy consumption have driven the development of efficient high-performance energy storage systems. Supercapacitors or electrochemical capacitors are the most promising and efficient energy storage devices owing to their long cycle life, high power density, fast charging/discharging and better safety tolerance compared to batteries [1][2][3][4]. Supercapacitors are classified broadly into two categories: pseudocapacitors and electrical double layer capacitors (EDLCs).…”
