Nitrous oxide (N2O) is a common greenhouse gas and urgent need to be contained. Direct catalytic decomposition of N2O by high activity catalyst into N2 and O2 is a low-cost and harmless method. Bimetallic catalysts show good catalytic activity in many classes of reactions, and plasma technologies, applied to prepare of catalyst, are considered to be a promising method. In our contribution, DBD cold plasma is applied to synthesize Rhodium and Cobalt bimetallic catalysts for catalytic N2O decomposition. The influence of cobalt and rhodium content on N2O decomposition activity shows that the optimal amount of metal is determined as 5wt. % cobalt and 0.5wt. % rhodium loaded on Al2O3. The best working voltage is determined as 18kV. The results indicated that the Rh/Al2O3 catalysts prepared by atmospheric-pressure DBD cold plasma showed smaller size and high dispersion of Rh particles, so that the metal-support interaction and the catalytic activity are enhanced. Atmospheric-pressure DBD cold plasma is proved to be an environmentally friendly and efficient method for preparing high performance Rhodium and Cobalt bimetallic catalysts for catalytic N2O decomposition.

Iron/palladium bimetallic nanoparticles (Fe/Pd NPs) are important catalytic materials for the field of environmental remediation. In the present study, filter paper was employed as a substrate for the assembly of Fe/Pd NPs and further applied for the catalytic conversion of hexavalent chromium Cr(VI) toward trivalent Cr(III). First, a filter paper with negative charge was assembled with a layer of positively charged polyethylenimine (PEI) through electrostatic interaction; then, the abundant amine groups of PEI were used to complex Fe(III) ions, followed by reduction via sodium borohydride to produce an Fe NP-assembled filter paper. Thereafter, the Fe/Pd NPs were produced by the reduction of PdCl42− through Fe NPs. The prepared filter paper assembled with Fe/Pd NPs with a mean diameter of 10.1 nm was characterized by various techniques. The Fe/Pd NP-assembled filter paper possesses powerful catalytic activity and can be used to transform Cr(VI) to Cr(III). With its low cost, high sustainability, and convenient industrialization potential, the developed approach may be extended to produce other bimetallic NP-immobilized filter paper for different environmental remediation applications.

In this work, hierarchical MoS2/C quasi-hollow microspheres are prepared by a one-pot hydrothermal process with the addition of glucose. The glucose is not only inclined to form the roundish sphere in the completion of the synthesis of MoS2, but at the same time the microspheres formed by the glucose can act as the nuclei on which the MoS2 grows. Glucose, acting as a nucleating agent, has the advantages of being low-cost and environmentally friendly, which can simplify the fabrication process. The interiors of the MoS2/C samples are multi-hole and quasi-hollow, which is beneficial for the insertion and extraction of lithium ions. For the first time, we demonstrate that hierarchical-structured MoS2/C quasi-hollow microspheres exhibit an excellent cycling stability and rate capability in lithium ion batteries (LIBs) and are significantly superior to the bulk MoS2. The method presented in this article may provide a simple, clean. and economical strategy for the preparation of MoS2/C microspheres as a feasible and promising anode material for LIBs.

Abstract To catalyse the decrease of triiodide in the electrolyte, state-of-the-art dye-sensitized sun directed cells (DSSCs) usually use respectable and uncommon Pt as counter electrodes, which greatly limits the practical applications of DSSCs. Appropriately, choices with low cost, fabulous electro- catalytic action, and predominant electrochemical stability to Pt are exceedingly looked for after. Herein, we report tin sulfide/reduced graphene oxide (SnS/rGO) composites are facile synthesized via a simple one-pot hydrothermal route and characterized by XRD, FESEM, Raman, UV-DRS, BET and PL studies. Due to the synergic effect between the SnS nanoparticles and rGO, these composite samples showed outstanding electro-catalytic property on reducing the triiodide. Therefore, the DSSC equipped with SnS/rGO nanocomposite CE achieved a power conversion efficiency (PCE) of 7.72%, which was higher than those of use SnS nanoparticles (5.21%). The improved mechanism of SnS/rGO nanocomposite was also discussed.
