Lanthanum sulfide-manganese sulfide/graphene oxide (La2S3-MnS/GO) composite thin film as an electrocatalyst for oxygen evolution reactions

Sonochemical construction of hierarchical strontium doped lanthanum trisulfide electrocatalyst: An efficient electrode for highly sensitive detection of ecological pollutant in food and water

“…In trivalent lanthanum compounds including halide, oxide, and sulphide, this sort of satellite structure has been seen frequently. The peaks of La 3d 3/2 were located at 852.5 eV and 856.3 eV, clearly suggesting that La is in its La 3+ oxidation state [6] , [7] . The same sample's S 2p core level XPS spectra revealed two significant peaks at 161.8 eV and 163.0 eV [35] , corresponding to the S 2p 3/2 and S 2p 1/2 spin orbit splits which is in good agreement with the literature ( Fig.…”

“…Among these, dilanthanum trisulfides (La 2 S 3 ) is the stable one consists of both positive (La +3 ) and negatively charged ions (S 2- ). Lanthanum metal having a unique band structure due to the existence of f-orbital electrons, which can generate d-π coordination complexes with aromatic ring carbons [6] . Besides, the sulfide groups could easily form an electrostatic bond with the sensing analytes and along with this, it enhances the porous and hydrophilic nature.…”

LSNR:GO template for BSA interaction, photo and sonocatalytic reductions of fluorescent dyes in aqueous solutions

“…XRD suggests there is no dissociation, with stronger interatomic forces generating prominent peaks at 2y = 30.591 and 411 for La 2 S 3 :GO with 0.29 and 0.21 nm d-spacings, respectively. 27 While Ce 2 S 3 :GO has peaks at 2y = 201, 30.141, 30.751, 471 and 571 with 0.443, 0.296, 0.290, 0.190 and 0.160 nm d-spacings of the lattice plane, respectively. 44 This has direct implications for PCPs, as a lattice plane develops different NHSs according to the d spacing.…”

“…PCPs of LGT infer intensification of molecular interactions to recycle a wastewater via hydrophobic and hydrophilic activities. The morphology, crystallinity, and redox activities of LSNR have never been reported yet [26][27][28] . The hydrophobic and hydrophilic interactions of 𝐿𝑛(𝑁𝑂 3 ) 2 .…”

“…The morphology, crystallinity, and redox activities of LSNRs have not yet been reported. [26][27][28] The hydrophobic and hydrophilic interactions of Ln(NO 3 ) 2 Á6H 2 O with BSA were extended to LSNRs and LGT in previous studies. 29 LSNRs and LGT could not unfold aq-BSA except by solubilising by using partial surface charges to interact with LGT.…”
