3D Porous MoS2-Decorated Reduced Graphene Oxide Aerogel as a Heterogeneous Catalyst for Reductive Transformation Reactions

“…The short scan analysis of respective elements was also performed to understand the elemental binding in MoS 2 -rGOA. The short scan spectra of C 1s show peaks at ∼284.5, ∼285.2, ∼287.0, and ∼289.2 eV, which corresponds to the CC, C–O, CO, and −C(O)–O bonds, as shown in Figure c. , The deconvoluted spectra of O 1s show peaks allocated at ∼531.3 and ∼533.2 eV that arises due to CO and C–O bonds, respectively (Figure d) . However, Figure e represents the deconvoluted spectra of S 2p, which shows peaks at ∼163.6, ∼164.8, and ∼168.5 eV that can arise due to the presence of S 2p 3/2 , S 2p 1/2 , and S–O bonds.…”

Nitrogen-Doped Carbon Nanoflakes by Acidic Charring of Microcrystalline Cellulose and Urea for the Rapid Removal of Imidacloprid from Water

“…The XRD of carbonized N-CNF shown in Figure (e) shows two broad peaks located at 2θ values of ∼24.54° and ∼41.48°, corresponding to (002) and (100) planes, respectively . The (002) reflection plane depicts the graphitic planes, while the (100) plane represents the sp 3 -graphitic defects . The Raman spectrum given in Figure (f) displays two typical peaks on deconvolution and assigned to the G-band (∼1562.58 cm –1 ) for ordered sp 2 and the D-band (∼1344.21 cm –1 ) for defective sp 3 hybridized carbons, respectively.…”
