Room temperature Na-ion batteries(SIBs) show great potential for use as renewable energy storage ***, the large-scale application of SIBs has been hindered by the lack of an ideal SIBs anode material. We synthesized MoS2 on carbonized graphene-chitosan(G-C) using the hydrothermal method. The strong interaction between the MoS2 and the G-C greatly improved the electron transport rate and maintained the structural stability of the electrode, which lead to both an excellent rate capability and long cycle stability. The G-C monolith was proven to enhance the electrical conductivity of the composites and served as a matrix for uniformly dispersing active MoS2 nanosheets(NSs), as well as being a buffer material to adapt to changes in volume during the *** as an anode material for SIBs, the MoS2-G-C electrode showed good cycling stability(527.3mAh g-1 at100 m A g-1 after 200 cycles), excellent rate capability, and a long cycle life(439.1 m Ah g-1 at 1 A g-1 after 200 cycles).

Adsorption and the combination of adsorption and photocatalysis are prospective strategies for treating lowconcentrationvolatile organic compounds (VOCs). Behind the adsorption technology of VOC treatments are carbon-basedmaterials with large surface areas and high VOC uptake. This review summarizes the research progress in carbon-basedadsorbents and adsorbent-photocatalysts for VOC removal. Firstly, the VOC adsorption performances of various carbonmaterials, including activated carbon, activated carbon fiber, biochar, graphene and its derivatives, and carbon nanotubes,are summarized, and the adsorption mechanism of VOCs on carbon materials is analyzed. Then, the VOC adsorptionphotocatalyticproperties of composites comprised of different carbon materials and photocatalysts are presented. Finally,perspectives on the adsorption and adsorption-photocatalysis of VOCs via carbon materials are proposed. This reviewprovides an optimal reference for the research and development of adsorbents and adsorption-photocatalysts of VOCs.

Developing high efficient Pd-based electrocatalysts for oxygen reduction reaction(ORR) is still challenging for alkaline membrane fuel cell,since the strong oxygen adsorption energy and easy agglomerative intrinsic properties. In order to simultaneously solve these problems, Pd/Co_(3)O_(4)–N–C multidimensional materials with porous structures is designed as the ORR catalysts. In details, the ZIF-67 with polyhedral structure was firstly synthesized and then annealed at high-temperature to prepare the N-doped Co_(3)O_(4)carbon-based material, which was used to homogeneously confine Pd nanoparticles and obtained the Pd/Co_(3)O_(4)–N–C series catalysts. The formation of Co–N and C–N bond could provide efficient active sites for ORR. Simultaneously, the strong electronic interaction in the interface between the Pd and N-doped Co_(3)O_(4)could disperse and avoid the agglomeration of Pd nanoparticles and ensure the exposure of active sites, which is crucial to lower the energy barrier toward ORR and substantially enhance the ORR kinetics. Hence, the Pd/Co_(3)O_(4)–N–C nanocompounds exhibited excellent ORR catalytic performance, ideal Pd mass activity, and durability in 0.1 mol L-1KOH solution compared with Co_(3)O_(4)–N–C and Pd/C. The scalable synthesis method, relatively low cost, and excellent electrochemical ORR performance indicated that the obtained Pd/Co_(3)O_(4)–N–C electrocatalyst had the potential for application on fuel cells.
