“…Besides, the complete graphitization of the samples also meant that a large amount of oxygen-containing groups were removed, and the carbon matrix shrinked strongly, thereby increasing its porosity. 34 As demonstrated in Figure 4b, the mesoporous pore size distribution of FeCo@NS-CA is 3−5 nm.…”

“…The comparison of CA (115 m 2 g –1 ) and the directly carbonized pristine wood without any modification (PC) (46 m 2 g –1 ) showed that the removal of lignin could improve the porosity and active sites of balsa wood. Besides, the complete graphitization of the samples also meant that a large amount of oxygen-containing groups were removed, and the carbon matrix shrinked strongly, thereby increasing its porosity . As demonstrated in Figure b, the mesoporous pore size distribution of FeCo@NS-CA is 3–5 nm.…”

It is necessary to correctly research and synthesize efficient and inexpensive catalysts to achieve reversible oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), which is also a prerequisite for zinc−air batteries (ZABs). However, it is still a huge challenge to manufacture electrocatalysts with durable and high electrocatalytic performance from biomass. Here, a convenient method of delignification was used to transform natural balsa wood into a layered porous carbon material, FeCo alloy supported on a N, S-doped wood-based carbon aerogel

“…Hydrothermal treatment can improve the pre-hydrolysis of organic matter in straw and produce solid and liquid rich in sugar. At the same time, alkali treatment will destroy the hydrogen bond in cellulose, and the spatial distance between cellulose increases, so that the composition, structure and properties of fiber are changed, and more free surface is exposed, with larger water and specific surface area and pore volume [20][21][22]. These two aspects can greatly promote the transformation of lignin and cellulose.…”

Due to the overuse of fossil energy, fossil energy is facing exhaustion. Agricultural biomass such as wheat straw waste is a kind of clean energy which can replace fossil energy and has important scientific research value and broad application prospect. In this paper, wheat straw was used as raw materials, and the straw was converted into lactic acid, oxalic acid and fumaric acid under alkaline hydrothermal conditions. Improve the yield of organic acid by optimizing the reaction conditions such as NaOH concentration, reaction time and reaction temperature. The optimum reaction conditions were as follows: NaOH concentration 1.5 mol/L, reaction temperature 250ºC, reaction time 3 hours, total organic acid yield 13.5%, lactic acid yield 12.1%. The results can provide a new way for the green production of organic acids, and realize the efficient utilization of agricultural waste, reduce environmental pollution. At the same time, can produce good economic benefits, ecological benefits and social benefits.

“…138 The unique structure of biomass resources has an impact on improving lithium storage. 130 In the case of SiO 2 / CNF from wood pulp, Wang et al 139 demonstrated excellent cycling stability due to the mesoporous structures of wood pulp fibers in the plant cell wall that facilitated ion diffusion. However, biomass resources are expensive in producing multistep processes, and most are not free-standing.…”

Lithium-ion batteries are promising energy storage devices used in several sectors, such as transportation, electronic devices, energy, and industry. The anode is one of the main components of a lithium-ion battery that plays a vital role in the cycle and electrochemical performance of a lithium-ion battery, depending on the active material. Recently, SiO 2 has garnered attention for use as an anode in lithium-ion batteries. SiO 2 has a high specific capacity, good cycle stability, abundance, and low-cost processing. However, the high expansion and shrinkage of the SiO 2 volume during lithiation/delithiation, low conductivity, and solid electrolyte interphase formation resulted in damage to the electrode structure and caused a decrease in SiO 2 performance as an anode for a lithium-ion battery. The modified properties of SiO 2 and the use of carbon materials as composites of SiO 2 are effective strategies to overcome these problems. This review focuses on analyzing the role of various carbon materials in composite SiO 2 /C to enhance the performance of SiO 2 materials.
