“…The isoconversional methods describe the kinetics of the process by using multiple single-step kinetic equations, each of which is associated with a certain extent of conversion and allows a complex (i.e., multi-step) processes to be detected via a variation in E a with a. Conversely, independence of E a on a is a sign of a single-step process. The isoconversional methods permit the effective activation energy of a process to be unambiguously estimated as a function of the extent of conversion [30,31]. The method can be effectively applied to the overall [32] as well as species-specific [33] rate data.…”

The co-precipitates, Ag 2 Cu(C 2 O 4 )ÁnH 2 O, of varying composition [Ag = (0.125, 0.25, 0.5, 1 and 2) %] have been prepared, identified and characterized by means of IR, XRD and SEM. The decomposition kinetics was studied by thermogravimetry at four different heating rates: 5, 10, 15 and 20 K min -1 . Decompositions of the mixed oxalates were all complex exothermic processes with resemblance to the exothermic reaction of copper oxalate. The activation energies of the thermal decomposition were calculated using model-free equations; KAS, FWO, Vyazovkin and Tang methods and the values are found to be compatible with each other. The activation energy values of the decomposition reactions obtained from FWO and Vyazovkin are slightly higher than that obtained from other methods. The kinetic analysis of copper-silver oxalates prepared shows a decrease in average activation energy with increase in the concentration of silver oxalate. E a is found to increase with extent of conversion, which indicates the complexity of the reaction.

Bi2O2CO3 is a UV-light-driven photocatalyst. Bi2O2CO3 nanoflakes modified with plasmonic Ag nanoparticles (Ag/Bi2O2CO3) were obtained by a hydrothermal method. In the synthetic process, Ag2C2O4 worked as the Ag source and C source for the simultaneous formation of Ag particles and CO[Formula: see text]. The optimum synthesis condition was found at [Formula: see text]C for 16[Formula: see text]h under alkaline condition. The binary heterostructure was then used for degrading 2, 4-Dichlorophenol (2, 4-DCP) and Rhodamine B in visible light, with an efficiency of nearly 80% for 2, 4-DCP and 100% for Rhodamine B after 4[Formula: see text]h and 2[Formula: see text]h reaction, respectively. The binary heterostructure exhibited improved photocatalytic activity compared to that of individual Ag and Bi2O2CO3 due to Surface Plasmon Resonance (SPR) effect of Ag. Meanwhile, after five recycling experiments, Ag/Bi2O2CO3 showed higher photocatalytic activity and lower performance degradation in comparison with the one prepared by photo-reduction of Ag[Formula: see text] on Bi2O2CO3 nanoflakes. This indicated the advantage of one-pot synthetic method. This work is expected to provide an efficient photocatalyst for organic pollutants degradation.
