mers usually suffer from poor cyclic stability in long term charge-discharge processes. [ 15 ] The low electron conductivity of transition metal oxides leads to inferior rate capability. [ 16 ] In the search for high performance electrode materials, transition-metal sulfi des have been extensively studied as new class of pseudocapacitive materials for supercapacitors. [17][18][19][20] In particular, NiCo 2 S 4 possess higher electrochemical activity and higher capacity than mono-metal sulphides based on richer redox reactions. [ 21,22 ] More signifi cantly, NiCo 2 S 4 exhibited an excellent electrical conductivity, at least two orders of magnitude higher than that of NiCo 2 O 4 . [ 23 ] The development of novel nanostructured materials will effectively improve the utilization of active materials because of their high surface area, and short electron-and ion-transport pathways. Several different types of NiCo 2 S 4 nanostructures, including nanoplates, [ 24 ] nanoprisms, [ 25 ] nanotubes, [ 26,27 ] microspheres, [ 28 ] have been recently synthesized and their electrochemical performance was investigated. For example, Lou et al. [ 25 ] reported the fabrication of Ni x Co 3-x S 4 hollow nanoprisms through a simple sacrifi cial template method and a high reversible capacity (895 F g −1 under 1 A g −1 ) can be achieved. However, it should be noted that the introduction of a conductive agent and a polymer binder during the thin fi lm electrode preparation not only increase extra contact resistance but also inevitably compromises the overall energy storage capacity that still seriously limit their performance. [ 29,30 ] Three dimensional (3D) electrode architectures have emerged as a new direction because it can provide 3D interconnected network of both electron and ion pathways, allowing for effi cient charge and mass exchange during faradic redox reactions. Greatly enhanced performance has kindled the interest of researchers in the fi eld of 3D electrode architectures designs, such as copper pillar array, [ 31 ] nickel network, [ 32,33 ] stainless steel mesh, [ 34 ] carbonaceous interpenetrating structures. [ 35 ] The rigid electrode with metals as current collectors lead to the devices less fl exible, and they also have a low energy density. Carbon nanotubes sponge and graphene foams have been recently fabricated using chemical vapor deposition and used as electrode architectures for supercapacitors. [36][37][38] However, it is diffi cult to produce carbonaceous foams in large-scale because of their relatively high-cost and complex preparation processes. Additionally, due to the potential incompatibility issue between To push the energy density limit of supercapacitors, a new class of electrode materials with favorable architectures is strongly needed. Binary metal sulfi des hold great promise as an electrode material for high-performance energy storage devices because they offer higher electrochemical activity and higher capacity than mono-metal sulfi des. Here, the rational design and fabrication of NiCo 2 S 4 nan...

“…Additionally, by coupling with chemical activation, the specific surface area and surface chemistry of the final carbon products could be further improved and modified by adding special oxidizing agent. Various carbon materials with high specific surface areas and modified functional groups have been produced from biomass precursors for supercapacitors, such as cellulose, potato starch and eucalyptus wood saw dust [111], hemicellulose [112], paper pulp mill sludge [113], D-glucosamine [114], fungi [70], fungus [115], bamboo waste [116], microalgae [117], watermelon [118] and hemp [119]. For example, Sevilla et al produced microporous carbons from the microalgae by a HTC process accompanied with a post-KOH activation treatment (Figure 7(a)).…”

Electrochemical energy storage devices, such as supercapacitors and batteries, have been proven to be the most effective energy conversion and storage technologies for practical application. However, further development of these energy storage devices is hindered by their poor electrode performance. Carbon materials used in supercapacitors and batteries are often derived from nonrenewable resources under harsh environments. Naturally abundant biomass is a green, alternative carbon source with many desired properties. This review article presents state of the art of renewable carbon materials derived from natural biomasses with an emphasis on their applications in supercapacitors and lithium-sulfur batteries. IMPACT STATEMENTThis review paper provides a comprehensive understanding for obtaining renewable carbons from natural biomass precursors via various activation methods for electrochemical energy storage application, especially for supercapacitor and lithium sulfur battery.

Solvent-free aerobic oxidation of hydrocarbons and alcohols with Pd@N-doped carbon from glucose

The development of efficient systems for selective aerobic oxidation of hydrocarbons and alcohols to produce more functional compounds (aldehydes, ketones, acids or esters) with atmospheric air or molecular oxygen is a grand challenge for the chemical industry. Here we report the synthesis of palladium nanoparticles supported on novel nanoporous nitrogendoped carbon, and their impressive performance in the controlled oxidation of hydrocarbons and alcohols with air. In terms of catalytic activity, these catalysts afford much higher turnover frequencies (up to 863 turnovers per hour for hydrocarbon oxidation and up to B210,000 turnovers per hour for alcohol oxidation) than most reported palladium catalysts under the same reaction conditions. This work provides great potential for the application of ambient air and recyclable palladium catalysts in fine-chemical production with high activity.
