Abstract The achievement of the outstanding theoretical capacitance nickel sulfide (NiS 2 ) is challenging due to its low conductivity, slow electrochemical kinetics, and poor structural stability. In this study, we utilize polyaniline (PANI) as a linker anchor NiS with hollow bowl‐like structure, uniformly dispersed at surface graphene oxide (GO)(NiS @15PG). presence PANI provides growth sites, resulting in uniform dense arrangement . This morphological modulation increases contact area between active material electrolyte. Additionally, effectively connects conductive network GO, which advances electrical conductivity ion diffusion properties. As result, R ct (charge transfer resistance) Z w (Warburg impedance) @15PG decrease by 82.61 % 66.76 respectively. unique structure confers high specific (536.13 C g −1 1 A excellent multiplicative property 60.93 20 assembled @15PG//YP‐50 supercapacitors (HSC) demonstrates an energy density (13.09 Wh kg high‐power (16 kW ). capacity retention after 10,000 cycles 5 86.59 %, indicating significant potential for practical applications.

Cuins2-Mgo/S-Doped Biochar Heterojunction for the Efficient Adsorption-Photocatalytic Elimination of Cationic Dye

Опубликована: Янв. 1, 2023

Biochar is the promising material for environmental remediation because of its adsorption and photocatalytic activity. To further boost adsorption-photocatalytic performance biochar in RhB removal, CuInS2 MgO were applied to modify S-doped (CIS-Mg/S-BC) via one-pot approach. The photo-induced electrons holes efficiently separated migrated at junction interface among CuInS2, MgO, biochar, enlarging visible light absorption conversion harmless products. functional groups active sites CIS-Mg/S-BC favored adsorption. Langmuir second-order models well described isotherms kinetics S-BC-based hybrids, respectively. presented higher activity than S-BC, d-Mg/S-BC 2-CIS/S-BC visible-light region. best removal efficiency over 2d-CIS-Mg/S-BC 400 mg L-1 solution was 97.67% within 120 min while reduced 95.62% after five cycles, estimated qe model 800.37 g-1.
