In recent years, nanofibrous materials derived from biopolymers have attracted more interest due to their numerous applications. In our study, a simple composite of cellulose nanocrystals, and cobalt oxide nanoparticles was elaborated using sodium borohydride as a chemical reducer. It has been shown that Co3O4 nanoparticles were grown on the surface of cellulose nanocrystals. An important quantity of cobalt oxide nanoparticles was detected using ICP-OES (13.5 g contained in 100 mg of the composite). The size, the morphology and the thermal stability of the composite and the obtained nanoparticles were studied using X-ray powder diffraction, Fourier-transform infrared spectroscopy, Ultraviolet-Visible spectrophotometry, Scanning electron microscopic and Transmission electron microscopic. Our obtained material was used for the degradation of Rhodamine B and it was succeeded in degradation of Rhodamine B within very short period of time (16 min). The catalytic degradation of Rhodamine B was investigated and analyzed with UV-Visible absorption spectra.

“…This behavior has been ascribed to a highly exothermic rate determining step. Oxidative degradation of rhodamine-B (RhB) with NBS in aqueous and different water alcohol solvent mixtures has been investigated over varied conditions of [RhB], [NBS], pH and temperatures [14]. The reaction exhibited a first-order dependence on…”

The kinetics of the electron transfer in sofosbuvir (Sofo) using N-bromosuccinimide (NBS) in aqueous medium has been studied spectrophotometrically over the (10-30) °C range, (0.1-0.5) mol dm −3 ionic strength, pH = 6.0-8.0 range over a range of NBS and Sofo concentrations. The rate of reaction was first order dependence on both [NBS] and [Sofo] and decreased with increasing [H + ] over the range studied suggesting that the deprotonated form of sofosbuvir is more reactive than its conjugate acid. The hydrogen atom attached to the nitrogen atom of pyrimidine dione ring has a highly acidic character due to withdrawing effect of the adjacent two carbonyl groups and so the sofosbuvir acted as an acid. The rate decreased with increasing the ionic strength of the reaction mixture and supported that the reaction took place between two ions of different charges.
